Your Heart Powers You.
And Electricity Powers Your Heart. Electrophysiology Cares for That Electric System.
To understand cardiac electrophysiology, you need to understand the basics of the heart. The human heart has three main components, which we’ll call:
The Pump – the main muscular mass
The Plumbing – all the arteries through which the blood flows
And the Electrical System – a system that generates and regulates the heart rhythm
The heart has a normal flow of electrical impulses from one part of the heart to another. These impulses cause the heart to contract and relax, which pumps blood to the body and vital organs.
Electrical impulses in the heart are generated by natural “pacemakers” and conducted by certain electrical “cables” or pathways. Abnormal electrical impulses cause the heart to beat too slowly, too fast, or irregularly. These electrical heart rhythm abnormalities are called arrhythmias.
An arrhythmia is any deviation from or disturbance of the heart's normal rhythm. Arrhythmias may be harmless or serious and even life-threatening. The consequence of an arrhythmia depends primarily on the structural condition of the heart and the presence of heart disease.
Electrophysiology is a subspecialty of cardiology that diagnoses and treats heart arrhythmias or problems related to the heart’s electrical system.
