ECG

An ECG (electrocardiogram) is a medical test that measures the electrical activity of the heart. It records the timing and strength of electrical signals as they travel through the heart, providing insight into its rhythm, heart rate, and overall function. The ECG is typically used to detect heart conditions such as arrhythmias, heart attacks, and other cardiac issues. Small electrodes are placed on the skin to capture the heart's electrical signals, and the results are displayed as a series of waves on a graph.
