Electrophysiologic studies for pacemaker selection.

Decisions regarding proper pacemaker selection are becoming increasingly complex. With the advances in pacemaker technology it is important to determine not only if permanent pacing is indicated but what type of pacemaker will be most effective. Antitachycardia pacing is becoming a more accepted treatment option in patients with disabling or life-threatening arrhythmias. With all the ongoing changes in cardiac pacing, electrophysiologic testing becomes an increasingly important and necessary tool in the evaluation of patients with complex conduction and rhythm disorders.
