Can sinus bradycardia cause constant low heart rate?
Patient: I have a low heart rate--48-52 pretty much all the time--I have had a stress test that showed evrything ok--however--I am always exhausted and one of the ekg's showed sinus bradycardia consistent with anterseptial infarct--Since I had the stress test --and it as okay--is there anything to be concerned with Doctor: Hello,I don't know if your electrocardiogram (ECG) seen by a doctor or you just have seen the computer reading. I am considering the first one, so you have past myocardial infarction, and now your stress test was okay, and you have sinus bradycardia and feels exhausted. Well, its good that stress test was okay. If you are taking beta blockers that are common in a patient who had infarction you should see the doses you take and probably low these doses or change the beta blockers. I recommend echocardiography, 24 hours ECG recording and a visit to the cardiologist.Hope I have answered your query. Let me know if I can assist you further.Regards,     Dr. Anila Skenderi
