Pacemaker & Defibrillator Clinic

Dr. Villafañe established the first formal pacemaker clinic over 30 years ago. Our pacemaker clinic will see children, adolescents and adults with pacemakers or defibrillators.

At our pacemaker clinic we use a specialized pacemaker/defibrillator analyzer which will interrogate the generator unit and acquire vital information such as battery life, and lead condition, and will also detect any dysrhythmia.

During the pacemaker/defibrillator evaluation Dr. Villafañe performs stimulation and sensing thresholds to be sure that there is a safety margin between the generator unit's electrical output and the hearts electrical demands.
