Mario D. Gonzalez is a professor of medicine at Penn State Hershey College of Medicine and program director of electrophysiology at the Penn State Hershey Heart and Vascular Institute.

Dr. Mario Gonzalez, program director of electrophysiology with the Penn State Heart and Vascular Institute at the hospital, took charge of the case.

"We couldn't control (Eisenhauer's heartbeat) with medicine, so we did a procedure called catheter ablation," Gonzalez explained.

Catheter ablation is a technique designed to destroy parts of the abnormal electrical pathway that is causing an abnormal heart rhythm. In it, Gonzalez said, catheters are inserted into the heart through veins in the groin.

Gonzalez said five or six catheters are used to record the electrical activity of the heart on a computer system in the operating room.

"We use a computerized mapping system, so we can get an accurate identification of the site, exactly where the abnormal electrical rate is coming from," he said.

The doctor then passes heat energy through the catheter near the source of the abnormal electrical pathway, burning the heart tissue containing that pathway.

Once the pathway was destroyed, his heart recovered completely, the doctor said.

Patients who have arrhythmia may feel palpitations, shortness of breath, chest pain or dizziness, or they may pass out, Gonzalez said. But when the condition continues over a long period of time, the heart gets weaker and weaker.

Gonzalez said the procedure has been used for years, but with today's technology it is safer and much more sophisticated and successful.

Not many surgeons do the procedure, and Gonzalez is internationally known for his unique procedures, according to Brent Heard, an HMC marketing and communications specialist.

"Twenty years ago, it was a pretty primitive procedure," Gonzalez said.
