Hello. Welcome to HCM. Thank you for your question. I understand your conern.
First, I suppose your doctor also informed you that lisinopril does not exert such effect like lowering the
heart rate, thus reducing the palpitations. Also, lisinopril and other ''prils'' can cause dry cough as a side effect. I am assuming you had
high blood pressure and that is why your doctor prescribed lisinopril.
In this point that we are standing, I would recommend you to do an EKG, to clear what these palpitations are; an
echocardiogram to re-evaluate your
mitral valve prolapse and if it is causing
mitral regurgitation (returning of the blood through the mitral valve during systole, when it is normally shut) and, if so, what grade is it and does it correlate with symptoms; also, a 24-hour Holter rhythm registration, to see how often the palpitations do happen during a day. It is only when these tests are performed, you can discuss treatment strategies with your curing doctor.
I hope I was helpful with my answer. Feel free to contact me again.
Best regards,
Dr. Meriton
