I have been suffering from rapid heart beats and left side chest pains accompanied by dizziness and generalised weakness in limbs for last couple of months almost every other day. I have had my conventional angiogram 6 months back which normal coronaries but have a myocardial bridge which is told something common. I had a TMT an year back which came normal as well. I am on concor 5 mg. Today I have a weird symptom. My morning BP was 117/70 and heart beat was around 80. And all of a sudden I have a pain and weakness in legs and momentarily shock feeling in heart which raised my heart beat and BP to 160/80 and just after 2-3 mins my BP came around 123/82 and HR 80 but weakness in legs and dull left chest ache is there. Is MB causing these symptoms?
