The electrocardiogram (ECG) is an instrument used to record heart electrical events by measuring voltages during depolarization and repolarization. It distinguishes between normal and abnormal heart function based on recorded traces.
Electrocardiogram (ECG) is the instrument used to record the electrical events of the heart by measuring the voltages created during depolarization and repolarization processes. Electrodes placed on the chest detect these electrical signals, helping in diagnosing heart conditions.
ECG records the activity of the heart's conducting and contracting cells, such as the SA node, AV node, and myocardium cells. It distinguishes between normal and abnormal heart function based on the captured traces.
Standard ECGs usually involve 12 or more electrodes placed on the patient's skin at specific locations to ensure accurate recording of heart function.
