Electricity, brain electricity, stomach electricity etc., these electric signals are all the reactions of human body particular organisms electric signal source electromagnetic field essence, monitor and understand
The physical features of these electric signals can diagnose all kinds of physiological maladies.For example, electrocardiosignal is the bioelectrical signals of heart itself
By conductive tissue and body fluid, it is transmitted to body surface skin, parts of body epidermis is made also all to be sent out in each cardiac cycle
Raw regular change in electric.It places an electrode within human epidermal privileged site to measure, records the song of cardiac electric signals
Line is to obtain intuitive electrocardiogram, and when heart is in, heartbeat is normal, too fast, excessively slow or heart beat rhythm changes, cardiac muscle lacks
When the different situations such as blood, obstruction, impaired, necrosis, electrocardio-activity can correspondingly show normal or abnormal variation, and be reflected in the heart
On electrograph, to provide analysis or diagnosis normal ECG, arrhythmia cordis, ventricular hypertrophy, myocardial ischemia, myocardial infarction for doctor
Etc. healths of heart or disease report foundation.Therefore, including electrocardio etc. it is bioelectric it is real-time monitoring medically to disorder in screening,
Early detection and diagnosis are significant with prevention and control.
