Question : I take Inderal 10 before bkfst, for tachycardia (110 b/m) and bp (150/95). ECG is normal. Now I wake up every morning on fast bouncing heart beats.
Brief Answer:
Appropriate treatment; maybe a switch within the same drug class
Detailed Answer:
Greetings. Welcome to HCM and thank you for your question. I understand your concern.
In the morning, there are a lot of hormones that reach their peak levels during this time of day (such as cortisol and epinephrine), which stimulate the organism's waking up. These hormones have properties to affect the heart rate and the blood pressure by various mechanisms, especially by narrowing (constricting) the arteries. Now, to overcome this "resistance of the peripheries", heart has to do more work, hence the forceful heart beats. Although propranolol (Inderal) is an effective beta-blocker, my opinion is that switching to atenolol or metoprolol, at this time, would be in order, to keep the heart rate under 100 beats per minute and blood pressure under 140/90 mmHg. You may discuss with your cardiologist, about the dosage and frequency of taking.
I hope mu answer is helpful. I am happy to help, if you have follow-up questions.
Kindest regards,
Dr. Meriton
