Description

Portable device and method for heart state measurement

The invention relates to a measurement device and method, in particular to a portable device and method for heart state measurement.

Heart disease is a general term for heart disease, including rheumatic heart disease, congenital heart disease, hypertension heart disease, ischemic heart disease, coronary heart disease, myocarditis, heart valve disease and heart failure... and other heart diseases. Common symptoms include: indigestion, nausea, upper abdominal pain, difficulty breathing, palpitations, extreme fatigue, edema of the extremities, dizziness, breathlessness, fainting, sweating, pulse, or tachycardia.

But heart disease is often sudden, paroxysmal, without obvious incentives or warnings. The most terrible heart disease is the sudden death of a heart attack. Sometimes it is asymptomatic at rest or at rest, but heart disease is induced after activity or stimulation.

According to the latest statistics on the cause of death of Chinese people in 105 years released by the Ministry of Health and Welfare, the top ten causes of death are (1) malignant tumors (cancer) (2) heart disease (3) pneumonia (4) cerebrovascular disease (5) diabetes (6) Accidental injury (7) Chronic lower respiratory tract disease (8) Hypertensive disease (9) Nephritis, nephrotic syndrome and nephropathy (10) Chronic liver disease and cirrhosis. This sequence shows that heart disease is still one of the important causes of death for Chinese people.

In addition to maintaining basic good living habits, regular check-ups are also extremely important. Especially for patients with a potential risk of heart attack, it is more important to measure and check at any time.

Generally speaking, patients with high-risk group of heart disease need to wear a 24-hour ECG instrument for continuous ECG monitoring (Holter Monitor) according to the doctor’s order, and continuously record the patient’s cardiac electrophysiological response in the home environment to provide the physician to read Take the data and determine if there are any abnormalities.

However, this type of Holter Monitor cannot simultaneously measure the electrocardiogram signal and identify the abnormal characteristics of the collected signal when monitoring the electrocardiogram, and provide early warning. In addition, according to the CPR Guideline, it is clearly pointed out that the use of electrocardiograms to detect early heart diseases has its limits, which means that some patients still have ECG rhythm signals during the onset of heart disease. , But the heart has stopped beating, this phenomenon is called cardiac arrest signal. Therefore, only by simultaneously measuring the signals of the electrocardiogram and the cardiogram can we grasp and recognize the electrophysiological and mechanical physiological responses during the heart beat cycle.

In recent years, wearable medical devices have been gradually developed, and the demand range is growing fast. Because wearable medical devices are different from Holter Monitor, they can monitor and prevent heart disease at any time by measuring heart rate and cardiac electrophysiological changes at any time. . Furthermore, whether it is the healthcare industry or the general public, the sooner the disease is found, the lower the hospitalization rate, or the related costs, thereby driving the development of the wearable medical device market.

However, wearable medical devices still face two important considerations. One is the accuracy of measurement data. How to improve the detection accuracy of wearable medical devices in different states (sports, sit-in...) is a subject to be developed and solved The second is convenience.
