Hi Doc, My father pulse id fluctuating between 55 to 65 . Oxygen is 99. Do I need to worry. Is it because of BP? Or anything else. Last time when checked his bp was 137 /79. He is taking his bp tablets regularly. Recently he was diagnosed with covid + but recovered in 7 days. I am concerned about his pulse. Pls guide should go visit doc in person ? Now a days situation outside doesnot allow to step outside the home. Pls guide.
