Cardiac Electrophysiology at Mission Heritage Medical Group
Electrophysiologic (EP) testing provokes known but infrequent arrhythmias.
Using local anesthesia, temporary electrode catheters are positioned in
the heart’s atria and/or ventricles and at strategic locations along
the conduction system. Our Mission Heritage Medical Group experts record
cardiac electrical signals and “map” the spread of electrical
impulses during each heartbeat. This shows where the heart blocks it.
Most significantly, it also triggers latent tachycardia or bradycardia.
Induced tachycardias can usually be stopped by rapid pacing via the electrode
catheters. Being able to "turn on" and "turn off"
tachycardias during electrophysiologic studies allows antiarrhythmic drugs
to be tested quickly for effectiveness. This can be done during a single
study using intravenous therapy or during short follow-up studies with
oral medication. Electrophysiologic testing has been performed safely
worldwide; complications only rarely occur.
