The additional symptoms that you have now may be caused by drugs. A dry cough is one of the most frequent side effects of ACE inhibitors. Dropping the Altace might eliminate it.
Metoprolol is a beta blocker. They generally slow down your heart rate and can cause fatigue and other side effects. "Common side effects of beta blockers are fatigue, low pulse, nausea, nightmares, occasionally shortness of breath, depression, etc."
Since you don't have high blood pressure, you probably don't need to be on these drugs.
You do need to find another cardiologist who is willing to take the time to determine the true root cause of your problems.
Good Luck.
