Electrocardiography - Wikipedia
Electrocardiography is the process of producing an electrocardiogram (ECG or EKG [a]), a recording of the heart's electrical activity through repeated cardiac cycles. [4] It is an electrogram of the heart which is a graph of voltage versus time of the electrical activity of the heart [ 5 ] using electrodes placed on the skin.
Electrocardiogram (ECG): Parts, Principle, Procedure, Types
2023年9月4日 · Electrocardiogram, commonly known as ECG or EKG is a medical test report indicating the heart’s electrical activity and rhythm during repeated cardiac cycles. It is printed on grid paper called the ECG strip or ECG tracing. The process of producing an electrocardiogram is termed electrocardiography.

2023年6月6日 · An ECG is used to check how the heart is functioning. It mainly records how often the heart beats (heart rate) and how regularly it beats (heart rhythm). It can give us important information, for instance about possible narrowing of the coronary arteries, a heart attack or an irregular heartbeat like atrial fibrillation. Go to:

2024年10月25日 · electrocardiography, method of graphic tracing (electrocardiogram; ECG or EKG) of the electric current generated by the heart muscle during a heartbeat. The tracing is recorded with an electrocardiograph (actually a relatively simple string galvanometer), and it provides information on the condition and performance of the heart.
