[|Human|] My husband 39 yo, runner began complaining of tightness and SOB. The doctor performed an EKG and the results were Sinus bradycardia with occasional Premature ventricular complexes and nonspecific ST abnormality. His heart rate ranged from 49-60 during the test
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Your husband is having ECG abnormalities and symptoms (tightness of chest and shortness of breath) suggestive of Brady arrhythmias and heart block. So better to consult cardiologist and get done Holder monitoring (24 hours continuous recording of ECG), stress echo and electrophysiology study (EP study). If he found to be had heart block then pacemaker insertion is the treatment. So consult cardiologist and discuss all these. Hope I have solved your query. I will be happy to help you further. Wishing good health to your husband. Thanks.
