In another "first" for the Heart Institute of Winthrop-University Hospital, a dual chamber defibrillator was successfully implanted in a 62- year-old Mineola man on July 29, l997. The new medical device had just been approved by the U.S. Food and Drug Administration during the week of July 21, 1997, and was used almost immediately to save the life of this local resident.

The patient - the father of nine children and grandfather of 12, whose wife is a Winthrop volunteer - sought medical help after several dizzy spells during which "the room started spinning."

Electrophysiology testing - a heart rhythm test similar to an angiogram - revealed that the patient had experienced a painless, though life-threatening ventricular arrhythmia. Previously, in l986, he had suffered a "silent" (painless) heart attack. This time, ventricular tachycardia - VT - almost cost him his life.

Within hours of the implantation procedure, the patient was walking, reading, feeling strong, and looking forward to playing with his grandchildren. His incision was less than three inches in length.

The dual chamber defibrillator, which incorporates a dual chamber pacemaker in a single container just slightly larger than a typical beeper, diagnoses, monitors, and treats ventricular tachycardia (VT) - rapid and irregular rhythm disturbances, which, if occurring in the lower chambers of the heart, can cause sudden death. Once the life- threatening rhythm is detected, the device emits a measured electrical impulse to defibrillate and "reset" the heart back to a normal rhythm.

Todd Cohen, MD, Director of Winthrop's EP Lab and Pacemaker-Arrhythmia Center, performed the implantation in the Hospital's EP Lab, rather than in the conventional Operating Room - a more cost-effective setting.


The new dual chamber defibrillator streamlines the treatment of patients who require two separate devices: a dual chamber pacemaker for bradycardia and a defibrillator for ventricular arrhythmias. The device is actually slightly larger than its single chamber predecessor, and its two wires necessitate a more complex implantation technique - requiring the participation of a skilled EP Team.


Upper Chamber versus Lower Chamber Tachycardia
The striking clinical advantage of the dual chamber defibrillator is its powerful, lifesaving ability to discriminate between upper and lower chamber defibrillation - facilitating a more accurate diagnosis and a more appropriate treatment.

Defibrillator
Upper chamber defibrillation - supraventricular tachycardia (SVT) - is usually benign, while defibrillation in the heart's lower chambers - ventricular tachycardia (VT) - can be fatal. In the United States alone, 500,000 people die each year of VT. The dual chamber defibrillator also records, with greater sophistication than previous devices, a more complete analysis of the patient's arrhythmic episode for retrieval by the doctor. This helps with the identification of the origin and cause of the problem.

For many patients, the new device will eliminate the need for a second implantation in the future.

Candidates for the new, one-step device are those who have experienced a life-threatening ventricular arrhythmia, including high-risk patients with weakened heart muscles, blockages of the coronary arteries, and non-sustained, asymptomatic VT.
