Cardiac Device/Electrophysiology Clinic

Pacemaker and Pacemaker Analysis
A pacemaker is a small device that is implanted to help control abnormal heart rhythms or heart rates. This device uses low-energy electrical pulses in order to help the heart beat at a normal rate.

Once a pacemaker has been implanted, it needs to be analyzed in the office once or twice a year. In addition, the patient needs to have the pacemaker checked over the telephone every month or every other month depending on the age of the pacemaker.

The telephone checks are to evaluate two basic parameters:

  • The status of the battery
  • The competence of the connections from the pacemaker to the heart

If a problem is found, the patient will be advised to have further evaluation.

Implantable Cardiac Defibrillator (ICD) and ICD Analysis
An ICD is a small device that is implanted to detect abnormal heart rhythms. If a dangerous and potentially lethal abnormal heart rhythm is detected the device will deliver an electric shock to restore a normal heartbeat. ICDs have been very useful in preventing sudden death in patients with known, sustained ventricular tachycardia or fibrillation. Studies have shown that they may have a role in preventing cardiac arrest in high-risk patients who haven’t had, but are at risk for, life-threatening ventricular arrhythmias.

Once an ICD has been implanted, it needs to be in the office twice a year. In addition, the patient needs to have the ICD checked over the telephone every one to three months.

Implantable Loop Recorder (ILR)
An implantable loop recorder is an insertable cardiac monitor which is a small device that is implanted under the skin in order to continuously monitor heart rhythms. It continuously stores information so that various arrhythmias can be detected which may be occurring very infrequently. This recorder is generally left in place for up to three years. Periodically, information is downloaded from the device to assess for any potentially unrecognized arrhythmias.

Cardiac Ablation
A cardiac ablation is a procedure that can help to correct abnormal heart rhythms such as atrial fibrillation, atrial flutter, supraventricular tachycardia, and ventricular tachycardia. The ablation works by scarring or destroying certain tissue in your heart that is responsible for triggering or sustaining an abnormal heart rhythm. The procedure is performed usually using long, flexible tubes called catheters which are inserted through a vein or artery in the groin and directed to the heart in order to deliver various energy forms to modify the tissues in the heart that are responsible for causing an arrhythmia.
