My husband has now had two episodes where he gets tightening in his chest , cold sweats, lightheaded. he just had an angiogram and there are no blockages. His father also died at the age of 44 from a heart attack , is there other heart issues it can be or could it be something else altogether. When he had the first episode we were in Galveston Texas on holidays and they mentioned Wolf Parkinson White. the episode the other day he was at work sitting at his desk and he said he instantly felt sick, cold sweat, dizzy. wanted to pass out and tightening in his chest. He had already been scheduled for an angiogram due to major changes in his stress test. Thanks for you help Denise
