ECG

When was the ECG invented?

ECG is a simple test that can be used to check heart rhythm and electrical activity. From Lippmann electrometer to string galvanometer, the measurement of ECG waveforms has gone through a long developmental stage. The electrical signals of the heart were first discovered by French scientist Mattencci in 1842. In 1903, Einthoven used a string galvanometer to record the first real electrocardiogram in human history, but this ECG monitoring device took up two rooms, weighed 272 kilograms, and required five people to operate at the same time. Subjects were required to immerse their hands and left foot in a saline solution to enhance conductivity and were required to continuously cool the electromagnets on the device with water.

This measurement method is not only complicated to operate, but also has errors in the acquired waveforms, and most of the ECG signals are submerged in the interference waves of the surrounding environment. Soon, with the discovery of semiconductors, from 1913 to 1933, the bipolar standard limb lead ECG and the unipolar lead ECG came out respectively. The emergence of electrocardiogram has made the diagnosis of heart disease from the era of feeling and stethoscope to the era of obtaining objective information with machines and technologies, and people have a deeper understanding of the changes in the structure and function of the heart under physiological and pathological conditions.

Norman J. “Jeff” Holter–“Father” of Ambulatory ECG Monitoring

In the 1990s, with the gradual maturity of wireless communication technology and network technology, the problem of remote ECG transmission was solved. The newly emerging hand-held ECG monitor integrates the ECG acquisition unit and the transmitting device. The bottom electrode of the device contacts the chest wall to form a circuit. After collecting ECG signals, it transmits ECG data using a mobile communication network. The acquisition and transmission of ECG signals is no longer the main problem, and the remote monitoring of ECG has been initially realized.

In 1957, Dr. Holter invented a method of using a storage record box to record the patient’s 24-hour ECG according to clinical needs and scientific and technological progress, abbreviated as Holter. The electrocardiographic fluctuations of the leads have greatly improved the detection rate of arrhythmias, and it has become the most basic method for diagnosing heart diseases. However, ECG monitoring at this time still cannot realize real-time data transmission, and patients need to manually send data reports to doctors. Therefore, doctors cannot obtain the ECG waveforms of patients in emergencies, and the obtained ECGs still cannot bring effective information for subsequent diagnosis and treatment which cannot assist in the diagnosis of complex arrhythmias and arrhythmias.

Remote Care for Cardiovascular Health

Advances in digital technology have improved ECG equipment‘s efficiency of ECG and accuracy. Also, with the advancement of low-power circuits, ECG equipment is becoming more and more accurate and portable which gradually developing in the direction of digital intelligence and network sharing.

ECG has been widely used in clinical and scientific research in medical institutions at all levels, and people’s understanding of it has continued to deepen. ECG with non-invasive and multifunctional characteristics is no longer limited to the scope of cardiac diseases, but can also be used for non-cardiac Differential diagnosis of diseases, etc.

The breakthrough in the size of ECG equipment has integrated ECG monitoring into public life, and wearable ECG monitoring equipment that can be used for arrhythmia and other devices continues to emerge, which greatly improves the diagnosis efficiency of cardiac diseases. They break the barriers of time and place to Improve the diagnosis of occult diseases.

However, dynamic ECG detection often lacks data transmission functions and background analysis systems. The ECG monitor developed by Viatom is equipped with the AI-ECG artificial intelligence electrocardiogram analysis and diagnosis system, which can automatically analyze and diagnose the ECG data uploaded to the cloud, and give early warning to the patient’s ECG critical value in a timely manner. Rapid analysis helps doctors save time for reading pictures, solves the shortage of professional doctors in a large area, and realizes large-scale ECG remote monitoring.

AI-ECG is an intelligent ECG analysis system developed based on artificial intelligence and big data. AI-ECG Platform can be applied to resting ECG scenarios, and AI-ECG Tracke can be applied to Holter ECG scenarios. By the end of 2021, more than 9,100 medical institutions around the world have used AI-ECG, providing more than 160 million real-time ECG analysis services. The accuracy of diagnosis is more than 95.0%, which is comparable to the level of ECG medical experts. It is widely used in clinical routine static ECG analysis and diagnosis, dynamic ECG real-time monitoring and early warning, as well as bedside monitoring or home monitoring and other scenarios.

Blood Pressure Monitor

The First Blood Pressure Measurement in History

Before professional medical equipment was developed, blood pressure and blood oxygen measurements all required arterial incisions.
Blood pressure is the pressure of blood pushing against the walls of the arteries. In 1819, the doctor needed to insert one side of the short tube of the U-shaped mercury manometer into the patient’s artery to measure the blood pressure of the patient’s brachial artery. Although it is worth remembering the first time that blood pressure was measured, it is clear that the direct insertion of a tube into an artery to measure blood pressure can not be widely used.

After 80 years of development, in 1896, scientists combined a rubber ball, a rubber pouch armband, and a glass tube filled with mercury to form the prototype of the blood pressure monitor that people use today. When measuring, a rubber cuff is wrapped around a person’s upper arm, and the blood flow is blocked or restored by inflating and deflating the rubber ball, and blood pressure readings are obtained according to the pulsation and height of mercury in the glass tube. But the device can only measure arterial systolic blood pressure, and the data is not very accurate.

Blood Pressure Monitor

Mercury Sphygmomanometer

In 1905, Nikolai Kolotkov used a stethoscope to listen for Korotkoff sounds to determine systolic and diastolic blood pressure. So far, the most classic modern method of measuring blood pressure with mercury sphygmomanometer, known as the “gold standard”, was born. The mercury sphygmomanometer was widely recognized by doctors and nurses for a long time after its birth and was once the only standard for clinical hypertension diagnosis. However, the mercury sphygmomanometer has very high requirements for the user, which needs to hear the Korotkoff sound accurately, so the accuracy of the data is easily affected by the medical environment and the subjective factors of the doctor.

In addition, the mercury in the mercury sphygmomanometer can easily bring mercury pollution, which poses a huge threat to the human body and the environment. Mercury has strong volatility and adsorption, which can be toxic to the human body through the respiratory tract, skin contact, digestive tract, etc. An environment with a concentration of 1.2~8.5 mg/m3 will cause human mercury poisoning. Therefore, since 2000, some states in the United States have banned the use of mercury sphygmomanometers and mercury thermometers. At present, most countries in the world have banned the production and sale of mercury sphygmomanometers.

Blood Pressure Monitor

What are the innovations in blood pressure monitoring?

The development of engineering mathematics and integrated circuits has provided strong support for the birth of electronic sphygmomanometers, and the characteristics of easy data transmission and sharing are more suitable for the digital revolution of the medical industry. Therefore, electronic sphygmomanometers have gradually replaced the status of mercury sphygmomanometers and become the commonly used pressure measuring equipment. The electronic sphygmomanometer is more accurate than the mercury sphygmomanometer for auscultation and measurement of blood pressure, and it is not easily affected by the external environment, so both patients and professional doctors can operate quickly.

Viatom’s sphygmomanometer has intelligent compression technology, which is matched with the Lycra high elastic cuff to ensure that the sphygmomanometer provides the most suitable pressure output during the measurement process, and obtains accurate and reliable results on the basis of ensuring user comfort and saving measurement time to minimize errors caused by individual subjects.

Viatom launched a two-in-one ECG and blood pressure monitor in 2021. The addition of the ECG monitoring function helps users and doctors to sort out the relationship between the patient’s blood pressure and heart diseases such as arrhythmia and myocardial ischemia through clearer clinical data.

The construction of Viatom telemedicine system also includes blood pressure monitoring. BP2 connect can transmit blood pressure measurement values ​​to the data management platform through Wi-Fi. Doctors can obtain real-time blood pressure changes through remote blood pressure monitoring, and analyze abnormal blood pressure fluctuations in time. The ECG module of BP2 connect is also equipped with AI-ECG Platform, which can generate an electrocardiogram within 30 seconds and conduct free AI analysis through reports, which is an important symbol of telemedicine intelligence.

Pulse Oximeter

How has the Pulse Oximeter Changed Healthcare?

Oxygen is an indispensable condition for human survival. From the time the human body inhales air, oxygen is transported to various organs of body through blood for oxygen supply. Blood oxygen saturation (SaO2) is the percentage of the capacity of oxyhemoglobin (HbO2) bound by oxygen in the blood to the total capacity of bound hemoglobin (Hb, hemoglobin), that is, the concentration of blood oxygen in the blood.

The original blood oxygen saturation measurement method required puncturing the artery to collect blood from the human body, and then obtaining the value through a blood gas analyzer. This repeated blood sampling tends to lead to pseudoaneurysms in patients and can take up to 20-30 minutes to obtain results. But as hypoxic patients may suffer brain damage or even die within 5 minutes, this inefficient form of blood oxygen monitoring is not widely used.

The birth of concepts such as blood oxygen, blood pressure, and ECG helps people understand the relationship between symptoms and organs, and these indicators are slowly integrated into preoperative diagnosis and intraoperative monitoring. Therefore, it is imperative to create more sophisticated equipment to obtain accurate data. The birth of the computer and the continuous innovation of electronic technology have accelerated this process, and medical equipment has entered a new stage.

Pulse Oximeter

The First Commercial Pulse Oximeter

The measurement of blood oxygen has also transitioned from blood draw to non-invasive. In 1977, the world’s first pulsatile oximeter, OXIMET MET-1471 (desktop), was successfully commercialized. This oximeter used a halogen lamp as the light source of the pulse wave. After the finger probe received the light from the light-emitting diode, a silicon photodiode in the chassis analyses the transmitted light.

Benchtop oximeters have huge probes and heavy cables that limit the movement of medical staff and patients. And the high cost of the equipment and the bulky body determine that doctors can only measure the patient’s blood oxygen level briefly when the operation is necessary. The real-time, continuous and long-term blood oxygen monitoring required for clinical surgery cannot be met. Due to the limitation of equipment volume and power consumption, the concept of blood oxygen monitoring still remains in the hospital, and the necessity of blood oxygen monitoring is still unclear to individuals and families.

Pulse Oximeter

We are the Furture of Wearable Health Technology

In 2019, viatom innovatively launched the ring-type pulse oximeter, marking that the development of oximeter has entered a new stage. The size and accuracy of the device are no longer obstacles to wide application. The design of not easy to fall off and built-in vibration reminder made O2ring a great success once it was released. At present, more than 50 companies and hospitals around the world have purchased O2ring as a front-end data acquisition tool for sleep apnea monitoring and surgical monitoring.

Viatom is also innovative in bringing the concept of telemedicine to life. Traditional medical equipment can only be monitored in the hospital, the blood oxygen value may normal when patients are at the hospital, and abnormalities may occur again after leaving the hospital. O2ring remote version newly released by viatom in 2021 realizes the remote reading of blood oxygen data, which is no longer limited by the distance transmission of Bluetooth. Users do not need to manually share the report twice, and doctors do not need to record data by themselves. The real-time transmission of blood oxygen data effectively solves this problem. It also solves the defects of uneven medical resources and the high cost of human and material resources in traditional diagnosis and treatment methods.

Demand is the original driving force for the development of the industry, whether it is the aging of the global population, the soaring medical costs, the increasing emphasis on preventive medical care, or the promotion of the COVID-19 epidemic. From telemedicine to Internet medical care, AI medical care, People have been persistently exploring uncharted territories and promoting the progress and upgrading of the healthcare industry through the continuous development of technology.

From the application of information technology to the upgrading of medical informatization, information technology and other technologies are only used as a tool, but with the rapid development and continuous sinking of new technologies such as the Internet and artificial intelligence, the medical industry has gradually entered a golden age. The integration of innovative technology and the medical and health industry is the basis for the development of Viatom products. Whether it is introducing the miniaturization of heavy monitoring equipment into the concept of wearable medical equipment, or breaking the limitations of time and place to achieve real-time monitoring to improve the diagnosis and treatment of sleep-disordered breathing, or using artificial intelligence algorithms to drive ECG diagnosis, etc., it is al demonstrates Viatom’s ability to continuously innovate and reshape healthcare.
