I was diagnosed with Atrial Fibrilation in October. I have been taking Metroprolol and Propafenone since and has worked fairly well until about a week ago. My palpitations are back even with meds. Can you body get used to meds and stop working or could something be interfering? I did have a steroid shot 10 days ago for a sinus infection. Would that interfere with meds?
Hi, If palpitations went worse during steroid shots, it can have two possible causes1. Palpitation can worsen in case of any infection, especially if you have high temperature. So it could be caused by sinus infection2. After steroid shots electrolyte disbalance can occur, which can lead to palpitations would advise you to wait some time. In these two cases, they should disappear after some time. If there continue, see your doctor. Hope I could help nourishing you good health In case of further questions don't hesitate to ask
