If 2D echo, Echo, Tmt, Ecg, Chest X ray reports are normal, is there need to do angiography? My brother has chest discomfort and mild pain sometimes in left and sometimes in center when he gets pain he gets nervous and his heart rate increases to 90-98bpm but at other times when he is relaxed his resting heart rate will be under 68-72bpm. He regularly runs on treadmill for 20 -30mins for atleast 5 days a week no discomfort while running. He has acidity gerd problem from last 8 months completed the course and stopped the acidity tablets, no other health issues sugar & bp are also normal.. Got chest x ray also orthopaedic said no issues just gave vitamin tablets for 1 month and at some 3-4 points in chest when pressed he feels pain.. kindly reply confused the pain is due to heart, acidity, muscular or nerves problem..
