Electrogram - Wikipedia
An electrogram (EGM) is a recording of electrical activity of organs such as the brain and heart, measured by monitoring changes in electric potential. [1]
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 (ECG or EKG) - Mayo Clinic
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.
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.
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.

2022年9月13日 · Before having an electrophysiology procedure, you may have an electrocardiogram (ECG). This is a noninvasive screening that involves a doctor placing electrodes on your chest to help assess the...
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.
Electrograms (ECG, EEG, EMG, EOG) - PubMed
The term electrogram, from the Greek electro meaning electricity and gram meaning write or record, is the broad definition given to the recording of electrical signal from the body. In order that comparisons of electrical activity can be made against normative data, certain methods and procedures have been defined for different electrograms.
Electrocardiogram - StatPearls - NCBI Bookshelf
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.
Electrogram Definition & Meaning - Merriam-Webster
The meaning of ELECTROGRAM is a tracing of the electrical potentials of a tissue (such as the brain or heart) made by means of electrodes placed directly in the tissue instead of on the surface of the body.
