ECG

An electrocardiogram (ECG or EKG) is a medical test that records the electrical activity of the heart over a period of time. It's a common tool used by healthcare professionals to assess the heart's rhythm and activity, and it's often used in diagnosing various cardiac conditions.

An ECG is a non-invasive and valuable tool for diagnosing and monitoring heart conditions. However, it's important to note that an ECG provides only a snapshot of the heart's activity during the recording period, and some conditions might not be captured if they don't occur during that time.
