supraventricular tachycardia
"Following a knee replacement over two years ago I developed SVT...a runner for 35 years, I couldn't believe I had any issue with my heart. Hypertension, mainly due to heredity, but that is about all I can complain about. I lived with the problem for a year until 1/2016 when my doctor put me on metoprolol...this stuff was terrible. My heart rate would drop to below 50..or go higher than 90. Again I lived with this medication for a year until I thought about cardiac ablation. Before considering this method, my NEW Doctor prescribed flecainide. This was a game changer for me. Though I still have a "skip", I am functional and have much more energy and overall better wellness than I had not had for years."
