atrial fibrillation
"I was put on metoprolol for SVT & IST after other medications made me worse, dropped my blood pressure too low etc. Although it never completely disappated the issues, I was going from everyday occurances to every 3-6months between each episode. No problems getting the heart rate up in exercise (still quite the opposite actually! I can reach 180bpm after 5mins) 
Unfortunately it didnt stop the progression to AF. After 6yrs of SVT & metoprolol I was further diagnosed with AF. Dosage was increased from 25mg to 50-75mg per day. Starting to work a little better now in preventing rapid AF however I still get slow AF. 
Dry mouth, cold extremities & occasional dizzy spells have been all too common however definitely a small price to pay.
