Left Ventricular Dysfunction
"Just wanted to share my experience getting OFF metoprololER 25 mg, and switching to Diltiazem ER, 120 mg. After a pulmonary embolism (no symptoms except PVCs), I suffered PVC w/anxiety and panic attacks, even while treating blood clots with Coumadin. I was put on 25 mg metoprolol ER to help the anxiety and PVCs- it helped  immediately. I stayed on several years. I continued the dosage, and tried to stay/get in shape. I steadily gained weight, assumed it was age. Exercising felt impossible. After a year or so, I was also having afternoon hypotension upon standing quickly. I developed symptoms of asthma and chest tightness + fatigue. I was switched to Diltiazem. After 8 days of body adjustment (w/small amt Ativan 2 days), I again feel human."
