I am so sorry I am late getting here to welcome you. Thanks for your great introduction.
From reading your post you have a very complicated situation. I am very concerned re your statement, " I have had episodes of crushing chest pain and shortness of breath when lying flat or on my left side.It only lasts about 10 minutes or so and is accompanied by a low heart rate (about 45bpm)." This is a symptom of a heart attack and should be considered an emergency so if you have not already please do present to the ER or call you Dr. immediately if you experience this again.
Metoprolol reduces the force of contraction of heart muscle and thereby lowers blood pressure. By reducing the heart rate and the force of muscle contraction, metoprolol reduces the need for oxygen by heart muscle. Since heart pain (angina pectoris
) occurs when oxygen demand of the heart muscle exceeds the supply of oxygen, metoprolol, by reducing the demand for oxygen, is helpful in treating heart pain. 200mg sounds like a large dose but from the info I have read this is an acceptable dose.
My husband has cardiomyopathy but that is a broad term. Heart disease is called cardiomyopathy and it's cardiomyopathy that causes heart failure. His cause is different from yours.
My best advice - keep in close contact with your Dr. Please know I care and hope that you will post an update on how you are doing.
