I had excision of an atrial myxoma 8 weeks ago. My resting heart rate is now about 110.
I took Metoprolol for 3 weeks but I did not tolerate it and my heart rate was about the same. My cardiologist says my heart is fine not to worry but I am tired. How long does it normally take for the heart rate to return to baseline? I am scheduled to return to work in 2 weeks and am scared I will be to fatigued.
