An electrocardiogram, often called an EKG or ECG, is a medical diagnostic that uses electrodes applied to the skin to monitor the heart’s electrical activity over time. An ECG is primarily used to evaluate the heart chambers’ size and location, heartbeats’ rate and regularity, cardiac disease’s existence, and the impact of medications or heart-regulating devices like pacemakers.https://omninewsroom.com/borderline-ecg-2/
