electrophysiology lab is a specially equipped catheterization lab
devoted to rhythm, or heartbeat, problems. Here, physicians can correct
any number of problems, often by using extremely small electronic
devices implanted in the body and connected directly to the heart.
rhythm problems are caused by abnormal heart tissues. The abnormal
tissue creates alternate routes for the electrical pulse that cause the
heart to beat. These new pathways interfere with the heart’s normal
pumping action because the electrical signals aren’t being delivered
correctly. Catheter ablation uses a device called a transducer, carried
on the end of a catheter, to direct high frequency radio waves at the
abnormal tissue, destroying it. This restores the normal electrical
pathways so the heart can beat normally.
internal cardioverter defibrillator (ICD) is a tiny device that senses
and corrects abnormally fast heart rhythms. It is implanted in a small
pouch under the skin near the heart. The electrophysiologist uses a
catheter to thread the ICD connectors through a vein and attach them to
the heart muscle.
sense abnormally slow heart rhythms and correct them. Like an internal
defibrillator, it is also implanted just under the skin, and a
catheter is used to connect it to the heart.
