An Electrocardiogram
An electrocardiogram (ECG or EKG) is a diagnostic tool used to measure the heart's electrical activity. It is a non-invasive procedure that involves placing electrodes on the skin of the chest, arms, and legs. The electrodes detect the heart's electrical signals, which are recorded on paper or displayed on a monitor.
The ECG can provide important information about the heart's rhythm and function. It can detect abnormalities in the heart's electrical activity, such as arrhythmias (irregular heartbeats), conduction abnormalities, and damage to the heart muscle. It is commonly used to diagnose and monitor heart conditions, such as atrial fibrillation, heart attacks, and heart failure.
During an ECG, the patient lies down while electrodes are placed on the chest, arms, and legs. The electrodes are connected to a machine that records the heart's electrical activity. The test typically takes only a few minutes and is painless and non-invasive.
Interpreting an ECG requires specialized training, as interpreting results can be complex and challenging. A healthcare professional, such as a cardiologist, will typically review the ECG and provide a diagnosis or treatment plan based on the results.
