[|Human|] My husbands heart rate is 145 with a blood pressure of 120/102 he is an avid runner and has a heart murmur-- he is in excellent shape 6 3 180 lbs--- he thinks he can run today to get his heart rate back in rythym -- I don t think it is a good idea... any advice
[|AI|]  Hello! Welcome to Ask a Doctor service! I understand your concern and would explain that his symptoms could be related to a metabolic disorder or cardiac arrhythmia. Besides, his diastolic blood pressure values are high, which indicates arterial hypertension, even though his systolic blood pressure values are within the normal ranges. For this reason, I would recommend performing some tests: - a resting ECG and cardiac ultrasound-thyroid hormone levels for thyroid gland dysfunction- blood electrolytes for possible imbalance-kidney and liver function tests. An ambulatory 24-48 hours ECG monitoring may be needed in order to investigate for possible cardiac arrhythmia. In the meantime, I would recommend avoiding straining physical activity with this heart rate and blood pressure value. Hope to have been helpful! Kind regards,
