[|Human|] Cardiac arythmia symptoms.  Hi I am recovering from an aortic valve replacement, mechanical (Nov 22 2000).  I have recently developed arythmia and I am now  unable to lie flat on my back without the arythmia becoming more severe.  During the day the arythmia is presesnt but goes away when I exercise (walking)  I take previscon and beta blockers.  Should I return to my consultant for a check up.
[|AI|]  Hellothanks for posting here. Previscan is a blood thinner to prevent blood clots from forming on the mechanical valve. It has no role in arrhythmias. Beta blockers are effective in controlling arrhythmias. They also keep the heart rate in control. You must do well on beta blockers. If their arrhythmias interfere with your day-to-day activities, or you are having symptoms like dizziness or syncope, you must consider increasing the dose or changing to another arrhythmia controlling medication. Wishing you good health thank you
