Hi --- I had a very tough time with a botched cryo-ablation and pacemaker implant in New York, and then countless PAC's, PVC's, and bigeminy after that. Now in the Los Angeles area, I found only one ElectroPhysiologist who really helped me. He's a real thinker and is also amazingly good at adjusting pacemaker settings to reduce arhythmias. He is the only EP I can recommend in this area. His name is Dr. Leo Polosajian. His phone is 818 718-1600.
