high blood pressure
"I have VSD, a bi-cuspid Aortic valve and Mirtal valve regurgitation. I am 37 years old and have been taking metoprolol for about 1 year as a result of some tachycardia/palpitations I experienced a while back.  I have had pre-hypertension (139/80) nearly all my life due to an enlarged heart caused by my hearts inefficiency from its defects.  Metoprolol seems to have controlled the arrhythmia's, although I will get one from time to time, but nothing of any duration. I have noticed a substantial decrease in energy levels, making it quite difficult to lose the extra 50lbs I am carrying around.  I work out regularly but I have not lost a single pound. It has not really impacted my blood pressure at all. I take 25mg twice daily."
