Jennifer Matthews: Sue Moore knows a thing or two about racing hearts. After all, she's a teacher. She also had an irregular heartbeat which kept getting worse. Sue Moore: I ended up sitting outside on the floor asking another teacher to come and help me because I thought I was gonna' totally pass out. Jennifer Matthews: Sue went to Doctor Warren Jackman who uses a computer-guided system with magnets to perform an ablation. The ablation destroys the area of the heart that causes the irregular rhythm. Dr. Warren Jackman: It's the first use of robotic maneuvering of an ablation catheter in the heart. Jennifer Matthews: Large magnets on both side of the patients let the doctor change the magnetic field and guide the catheter through the heart. It also keeps the patient completely still. Dr. Warren Jackman: If the catheter were to move during the ablation, it could destroy that and would require a pacemaker. Jennifer Matthews: The magnets kept the catheter still for the 15- hour procedure. But keeping sue still is another story. Sue Moore: My energy level has increased, and I've not had a single episode since the procedure. Jennifer Matthews: And that's energy that every high school teacher needs. This is Jennifer Matthews reporting.
