Electrocardiogram (ECG or EKG) - Mayo Clinic
2024年4月2日 · The heart rate is the number of times the heart beats a minute. You can measure your heart rate by checking your pulse. But an ECG may be helpful if your pulse is difficult to feel or too irregular to count accurately. ECG results can help diagnose an unusually fast heart rate, called tachycardia, or an unusually slow heart rate, called ...
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 (EKG or ECG) Tests: Purpose & Types - WebMD
2024年2月11日 · An electrocardiogram, also called an ECG or EKG, is a simple and painless test that measures the electrical impulses of your heart to check for signs of heart disease. It's done through small...
Electrocardiogram - Johns Hopkins Medicine
An electrocardiogram (ECG or EKG) is one of the simplest and fastest tests used to evaluate the heart. Electrodes (small, plastic patches that stick to the skin) are placed at certain spots on the chest, arms, and legs. The electrodes are connected to an ECG machine by lead wires.
Electrocardiogram (ECG or EKG) | American Heart Association
2022年12月7日 · An electrocardiogram — abbreviated as EKG or ECG — measures the electrical activity of the heartbeat. With each beat, an electrical impulse (or “wave”) travels through the heart. This electrical wave causes the muscle to squeeze and pump blood from the heart.
Electrocardiogram (EKG/ECG) - Cleveland Clinic
2022年5月13日 · An electrocardiogram (EKG/ECG) uses temporary electrodes on your chest and limbs to monitor, track and document your heart’s electrical activity (which controls your heartbeats) for diagnostic purposes. A computer translates the information into a wave pattern your healthcare provider can interpret.

2023年6月5日 · An electrocardiogram (abbreviated as EKG or ECG) represents a recording of the heart's electrical activity. Willem Einthoven first invented it in 1902. An EKG is an integral part of the initial evaluation of a patient suspected of having a cardiac-related problem.
In brief: What is an electrocardiogram (ECG)? - National Center …
2023年6月6日 · The resulting ECG graph is called an electrocardiogram. Whether during routine examinations or heart diagnostics, many people have already had an electrocardiogram (ECG or EKG). But what does it actually measure, and what does the ECG curve show us?

2024年11月4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.
