Patient's Query

Hello doctor,

I am a 19-year-old male, no known health problems. My only symptom is a slow resting heart rate. I have seen it as low as 45. I feel perfectly fine, no syncope or dizziness.

I am not an athlete so I do not know why it is so low. Is this cause for concern? With heart block, the heart rate does not increase with exercise correct?

My heart rate is low at rest but increases as expected with exercise. Does this rule out a problem? If I had clinical bradycardia would not I feel bad as well?

Hello,

Welcome to icliniq.com.

Normal heart rate should be between 60 to 100 beats per minute. You are having bradycardia. It can be idiopathic without any cause. But it is better to get physically examined and if needed accordingly investigation can be planned.

Rule out hypothyroidism by serum TSH (thyroid stimulating hormone) estimation.

Rule out any cardiac cause if present by EKG investigation. Check sodium, potassium and calcium level if needed. If no cause is found, then no need to worry. Consult a physician for examination.

Same symptoms don't mean you have the same problem. Consult a doctor now!
