Hi. What if someone is on 3 BP meds and is in an exercise program

This answer was rated:

Hi. What if someone is on 3 BP meds and is in an exercise program but is unable to get heart rate to go over 80? Also, what if the top number is XXXXX while the bottom has been as low as 40 recently? He gets woozy feeling after taking some of them especially the clonodine and is worried that his heartrate won't go into the target zone. Any ideas?Thanks!

I am Dr. Arun and will be helping you today.

The blood pressure medications can be responsible for heart rate not going above the 80 per minute. Sick sinus syndrome is the other cause. Following causes also should be considered;

1) inferior wall myocardial infarction,
2) electrolyte disorders,
3) hypoglycemia (low blood sugar),
4) hypothyroidism (low thyroid).

5) sinoatrial block (SA block)

The diastolic blood pressure going low up to 40 can be due to;

1) Effect of the medications.
2) Aortic valve regurgitation (heart valve abnormality).

An echocardiography (ultrasound of heart), blood work for electrolytes, thyroid and sugar are likely to give the diagnosis.

Please feel free for your follow up questions.

Why do BP meds keep the HR low? Avapro,norvasc,clonodine....None of these slow HR?



How can you lose weight if you don't get into the TARGET HR?


What type of electolytes?Done on normal CBC? He has been slight hyponatremic.


You are very welcome.

Avapro, Norvasc and Clonidine, individually may not decrease the heart rate but in an individual, may prevent the heart rate to rise collectively. Also the other causes also need to be looked into like sick sinus syndrome. Though the target rate may not be achieved, weight reduction can happen (albeit slowly) with the exercises. The electrolytes done are potassium, sodium, chloride, bicarbonates, calcium and magnesium. A CBC does not incorporate it and have to be ordered separately.
