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.

2024年4月2日 · An electrocardiogram (ECG or EKG) is a test to record the electrical signals in the heart. It shows how the heart is beating. Sticky patches called electrodes are placed on the chest and sometimes on the arms or legs. Wires connect the patches to a computer, which prints or displays results.

2022年12月7日 · What is an EKG? 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 …

2024年2月11日 · What Is an Electrocardiogram? 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...

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.

2025年1月17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.

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.

Electrocardiography (ECG) is a quick, simple, painless medical test that measures the heart’s electrical impulses. During an ECG, the heart's electrical impulses are measured, amplified, and recorded.

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.

2023年6月6日 · 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? Our nerve and muscle cells communicate with each other using electrical and chemical signals. Regular electrical signals also control our heartbeat.
