Hello, 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.Dr. Arun
