Welcome to icliniq.com.
I have gone through your ECG (attachment removed to protect patient identity). The reports mentioned on ECG are machine generated and are frequently inaccurate. There is no clear-cut evidence of myocardial infarction on ECG. As you also do not have any history of chest pain, it is unlikely for you to have any heart attack. And yes, heart rate is low and it is sinus bradycardia. Do you have any symptoms of dizziness, syncope, etc? If not then it needs no action at the moment. However, you should undergo thyroid test to rule out hypothyroidism as a cause for low heart rate. Also, should undergo echo, which will additionally provide the assurance to rule out MI. Also, if echo is normal then should have TMT (treadmill test), which will help in ruling out minor blockages, subclinical ischemic heart disease and to look for maximum heart rate you achieve during exercise, which will help in determining the benign nature of sinus bradycardia if the adequate heart rate is achieved. Also, high bp can also cause low heart rate by a reflex mechanism. So you should have medicine for it. I guess you are not receiving any medicines like beta blockers which can reduce heart rate. You should have tablet Telma CTD (Telmisartan and Chlorthalidone) 40/12.5 mg once a day in the morning for hypertension so get it prescribed by a local doctor.
