The cardiologist had put me on diltiazem 25mg and the PA put me metropolol at the regular doctor's for my blood pressure. My chest was tight all the time always out of breath diltiazem made my ankles swell
Off both now and using natural treatments!!

I'm not surprised that your medical team has "outlawed" Diltiazem and Metoprolol at the same time -- I think they amount to a double-barreled attack on arrhythmia. According to <drugs.com> "Diltiazem is a calcium channel blocker. It is used to treat hypertension (high blood pressure), angina (chest pain), and certain heart rhythm disorders." It also is one of the first-option medication treatments for hypertension. Metoprolol is a common beta blocker used for hypertension and easing of heart beats.

In my case, A-fib is my problem along with hypertension. I'm taking Coreg (like Metoprolol a beta blocker). I was prescribed another calcium channel blockers (Amlodipine) a few years ago, but my nephrologist cancelled that and listed it as an allergen when she started me on Coreg (Carvedilol). Because of A-fib, I also am on a Coumadin (Warfarin anticoagulant) regimen to prevent clots from forming in my heart.

Mysteriously, the Coumadin failed me 20 months ago, and I suffered a "small stroke" that caused me some minor imbalance and uncoordination problems that have been overcome with physical therapy -- teaching my brain to pay attention, stop assuming what I want to do, and behave. It turns out that this brain behavior -- issuing subconscious signals and directives to certain nerves, muscles, and glands -- has a far broader effect on me than I ever imagined. Frequent urination, for example, is necessary -- not because my bladder is full to overflowing, but because my assumptive brain believes that's what I want to do when I draw a glass of cold water from the refrigerator or turn on the kitchen faucet or roll over in bed ! ! ! ! My nephrologist has me exercising my brain to break its tendencies to initiate urination on the basis of false signals from my environment . . . and I think I'm making progress! I also think my nephrologist is a miracle worker.
