ECG or EKG stands for Electrocardiogram. It is a diagnostic test that records the electrical activity of the heart to evaluate its rhythm and function.
An ECG is a non-invasive procedure that involves placing electrodes on the chest, arms, and legs to detect and measure the electrical impulses generated by the heart. The recorded electrical activity is then printed on graph paper or displayed on a monitor for interpretation by a healthcare provider.
An ECG can help diagnose various heart conditions, including arrhythmias, heart attacks, heart failure, and structural abnormalities. It is a commonly used test in routine physical exams, pre-operative evaluations, and for monitoring the effectiveness of certain heart medications and treatments.
The interpretation of an ECG requires specialized training and expertise. A healthcare provider, such as a cardiologist or a cardiac electrophysiologist, usually reviews the ECG results and makes a diagnosis.
