Question: Rapid heart beat after MV Repair

 Bobo49 - Mon Mar 10, 2008 7:46 pm

I had successful mitral valve repair five weeks ago and I'm doing well. I'm 58 and have always been in excellent health. My only concern is my rapid heart rate since OHS. It's usually around 100 at rest and goes up to 140-150 if I do anything physical. I don't feel bad or have any shortness of breath. My doctor does not seem concerned and has me on 12.5 mg of metaprolol twice a day and coumadin for another week or so. The betablocker (metaprolol) seems to lower my pulse to around 80 for three or four hours and then it's back to the races. Could you please explain why this is happening, how long it may last and if I should be doing something different in your opinion? My doctor is great but is usually rushed, seems to ignore my concerns and really doesn't answer my questions very well. Thanks in advance for any information you can provide me.

User avatar Hi Bobo49,

Mitral valve prolapse leading to OHS for mitral valve repair. This indicates that before surgery the Mitral Prolapse may be associated with significant Mitral Regurgitation, i.e. leaking back of blood from Left Ventricle to left atrium due to incompetent mitral valve. You are 58 and MV Prolapse is generally of a long duration illness. Thus your Left Ventricle could be dilated due to years of mitral Regurgitation and its pumping power [Ejection Fraction or EF] would be low. This low EF in turn activates the sympathetic nervous system in such a way that the heart rate would be remaining high to compensate for the low EF.

I do not have any first hand data on your case in my hand but if your Echo shows that your EF is significantly low, then, if your cardiologist agrees, a medicine called Digitalis may be in order to reduce the heart rate and improve the EF, if you have no contraindication to this medicine.
