Step 1: Introduction to ECG

ECG stands for Electrocardiogram. It is a medical test that detects heart problems by measuring the electrical activity generated by the heart as it contracts. The ECG can measure the rate and regularity of heartbeats, the size and position of the heart chambers, the presence of any damage to the heart, and the effects of drugs or devices used to regulate the heart, such as a pacemaker.
