I'm 17 years old. I started blazing about a year and a half ago. I never really did it that much when I first started maybe like once every two weeks. But I quit when soccer season was about to begin so that I could get back into shape and about a month after I quit something happend with my heart and I went to a cardiologist and I was diagnosed with Wolf Parkinson White Syndrome ( Aka SVT) and I went and had to get a cardiac ablation and everything seemed fine for about a month after that. I started blazing again after soccer season ended in spring. Probably about once or twice a week. After a while I started waking up with a slight pain in my chest and a feeling of heaviness. So I went back to the cardiologist and the did an assload of test and said everything looked good and my heart was in perfect shape and suggested that it might be a psychological problem -__- im 100% sure that Its not psychological. And the same symptoms have continued to go on and idk what this is and I was wondering if anyone else has experienced anything similar? And if maybe smoking has triggered this?
