What Causes Chest Pain Along With Irregular Heart Beats?

Yes My husband had 2 PTCA s one year ago, and has been experiencing non-ischemic chest pain, and irregular heart beats which are probably PVC s. He had them throughout his PTCA s. The chest pain and arrhythmias have gotten worse. He has vertigo, and can t function normally. He just had all sorts of tests, and they were all negative. It comes and goes, but most of the time he feels really bad. When he had his stress test he felt good that day. His history is that he had a VSD, and ASD Repair when he was 21 yrs old for endocarditis. We don t know what to do. He is now 60 years old, and has always been active, but not anymore. Thank you for taking my question. I am a Cardiac Surgery Nurse, and I have asked about an ablation, but the cardiologist discouraged it! God Bless!
