Levaquin and atenolol

I have had PVC's for years and have been on Inderal, and more recently Atenolol. My PVC's have been somewhat controlled. Even though I still experienced some, they were not a problem. Recently I became ill with the flu, and the doctor prescribed Levaquin. My heart beat became very irregular, pounding, and my doctor prescribed a halter monitor. When I returned the monitor, later that morning the dcotor called and said, "Meet me at the emergency room." I was in the hospital four days, trying to get my heart stabilized. And it has never been the same since.
