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.
An electrocardiogram (ECG or EKG) is an electrical recording of the activity of the heart. The typical meaning of an "ECG" is the 12-lead ECG that uses 10 wires or electrodes to record the signal across the chest. Interpretation of an ECG is the basis of a number of cardiac diseases including myocardial infarction (heart attack) and arrhythmias ...
14 sty 2021 · An electrocardiogram (ECG or EKG) is a register of the heart's electrical activity. Just like skeletal muscles, heart muscles are electrically stimulated to contract. This stimulation is also called activation or excitation. Cardiac muscles are electrically charged at rest.
An electrocardiogram (ECG or EKG) is a record of the electrical activity of the heart over a period of time. The instrument that makes the record is the ECG machine or Electrocardiograph. Willem Einthoven invented it.
6 cze 2023 · 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:
An electrocardiogram is also known as an ECG; the Dutch and German version of the word, elektrokardiogram, is shortened to EKG. It is a tool used to visualize, or “gram,” the electricity, or “electro,” that flows through the heart, or “cardio.”
