Electrocardiography
Electrocardiography (ECG) is the method of recordance of the electrical activity of the heart over a time period using electrodes placed on the skin. These electrodes help in the detection of the minute electrical changes on the skin that arise from the electrophysiologic pattern of heart muscle while depolarizing during each heartbeat. This record called the electrocardiogram (also known as an ECG), gives information about the part of the heart that triggers each heartbeat (the pacemaker called the Sino-atrial node), the nerve conduction pathways of the heart, and the heart rate and rhythm . Usually, an ECG is obtained if a heart disorder is suspected. This Heart Congress scientific program has been CME and CPD certified.
