Electro Physiology

Cardiac electrophysiology (EP) is the study of the electrical system of the heart.

Electrical currents, in the form of chemical ions, flow across the membrane of each cell causing voltage surges that set the heart in motion. When these electric signals are disrupted, and the heart contraction is not uniform, we have an abnormal heartbeat or arrhythmia. When the heart beats abnormally, its efficiency decreases and its capacity to pump blood is reduced. Extreme arrhythmia within the heart can lead to sudden death.

Other forms of Arrhythmias

• Ventricular tachycardia: a dangerous type of very fast heartbeat.
• Supraventricular tachycardia. This is a sudden, very fast heartbeat.
• Ventricular fibrillation: a dangerous fluttering of the heart muscle that doesn’t let it pump blood and can be fatal.
• Sudden cardiac arrest: when the heart suddenly stops beating.
• Long QT syndrome: a disorder of the heart that can cause sudden arrhythmias.
• Brugada syndrome. an increased risk of abnormal heart rhythms from the lower chambers of the heart.
• Other arrhythmias. Arrhythmias can be caused by pregnancy, medicine interactions, or metabolic problems.
