Hi, Arrhythmia especially Atrial Fibrillation (irregular heartbeat) is pretty common, especially during Pneumonia.  The episode is generally paroxysmal i.e. it occurs during that time only and mostly doesn't recur back. If it is treated at that time we generally do not give any medication but if there are certain risk factors like dilated heart chamber (Left Atrium) or heart dysfunction we continue it for prophylaxis. You can stop the medication if you don't have risk factors or the arrhythmia has never recurred again. If it has, and you are feeling side effects of beta-blockers than for such patients we can start on another type of anti-arrhythmic called calcium channel blockers (Tab Diltiazem). For BP, you have to check your BP daily and if it is normal on medication than you definitely need them if the BP is lower than 110/70 you can try tapering the dose to half tablet and gradually stop it. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
