These may be treated using radiofrequency energy to eliminate (ablate) areas of abnormal conduction. Heart rhythm abnormalities are often the result of electrical "short circuits" in the heart. It is also useful in determining how effective medications are in controlling abnormal heart rhythms. The EPS is used to detect and diagnose any abnormal conduction of electrical impulses that may be responsible for heart rhythm disturbances. Through these leads, the electrical conduction of the heart can be studied, and any abnormal conduction can be identified. Potentially life-threatening heart rhythms that may cause sudden cardiac deathĪ cardiac EPS helps the cardiologist to identify:ĭuring the EPS, the electrical behavior of the heart that is responsible for controlling your heartbeat is recorded by placing conducting wires (or leads) positioned at strategic locations within your heart.However, in rare cases it can occur in individuals with structurally normal hearts and lead to sudden death. Ventricular fibrillation tends to occur mostly in diseased hearts. This results in the ventricles not being able to pump blood effectively to the rest of the body. VF occurs when the ventricles quiver instead of contracting normally due to disorganised electrical activity. V entricular tachycardia that lasts for more than a few seconds can degenerate into more dangerous arrhythmias, such as ventricular fibrillation. This is characterised as fast, regular beating of the ventricles that may last only for a few seconds or much longer. Ventricular arrhythmias include ventricul ar tachycardia and ventricular fibrillation.Ĭoronary artery disease (CAD), heart attack (myocardial infarction) and These begin in the ventricles and can be very dangerous, usually requiring immediate medical attention.
