Signal Averaged Electrocardiogram (SA ECG)

Signal Averaged Electrocardiogram (SA ECG) - What it is

The signal averaged electrocardiogram (ECG) is a special ECG that records the electrical activity of your heart over a period of 10 to 15 minutes. A computer scans the heartbeats for late electrical activity that occur after a normal contraction. This late electrical activity is a major cause of abnormal fast heartbeat which is not recorded by a normal ECG.

This test allows the doctor to identify patients at risk of a dangerous heart rhythm that may lead to sudden cardiac death.

There is no hospitalisation required.
