There is no other method can substitutes ECG at this aspect so far. Application: This product is suitable for testing and recording of ECG waveform and heart rate. “Timely testing” and “regular testing” of electrocardiograph are very important! Heart disease has the feature of instantaneity, if the user cannot test ECG shortly when feeling unwell, he maybe lose the right opportunity and delay the treatment. Therefore, it is very helpful for user to test ECG timely when heart disease occurred and for doctor to make a diagnosis and give right treatment. Timely testing: When feeling unwell, user can test the state ECG waveform and heart rate at once. Assistant diagnosis: Easy ECG monitor can record result in time, display ECG waveform and heart rate on screen clearly. The result can help doctor to make early diagnosis. Early prevention: Easy ECG monitor can record ECG waveform and heart rate, assist doctor to make early diagnosis; thereby heart disease can be prevented and diagnosed at the earliest time. Simpleness and speediness: ECG can be obtained rapidly by using palm electrode or chest electrode. Portability: Easy ECG monitor is small in size and light in weight, using battery power and easy to take. Easy ECG monitor can capture 8 heart syndromes within 30 seconds.
