What are electocardiagrams?

Electrocardiograms (ECGs or EKGs) are diagnostic tests that measure the electrical activity of the heart over time. They produce a graphical representation of the heart's rhythm and can help identify various heart conditions, such as arrhythmias, heart attacks, and other cardiac issues. The test involves placing electrodes on the skin to detect electrical impulses generated by the heart. ECGs are non-invasive, quick to perform, and provide valuable information for assessing heart health.
