Hi , about 6 weeks ago, I felt like I was having a heart attach , the pain was so intense in my chest area, and I was struggling to breathe, the paramedics came and ECG was normal, and they said it was muscular. I went to the doctors 2 weeks ago, to get checked out, chest X-ray satisfactory, bloods satisfactory, BP 105/60 pulse 44 SATS 97 ECG - normal with right bundle branch block Do you think this occurred when I had the pain after the attack?
