<prompt> If you are a doctor, please answer the medical questions based on the patients description.My husband has atrial fib and is on sotalol, has high blood pressure and was put on azor and since he was put on azor he has been back in afib twice and the last time has been 4 weeks and still is, saw cardiologist yesterday and wants to do another cardioversion he has had two in last 5 years, he did not want to talk about the azor since that was ordered by primary doc, I read that azor may interfere with atril fib is this true  <response>: Hello! Thank you for asking on Chat Doctor! Regarding your concern it doesnt look that your husband atrial fib recurrences have evidently anything to do with taking Razor. Amlodipine and Losartan the 2 components of Razor are not considered pro-arrhythmic Chat Doctor. A comprehensive investigation should be performed to find the eventually detectable reason of Aphid, including a current cardiomyopathy, any thyroid dysfunctions, etc. A careful maintenance therapy with Stall or even a more safe anti-arrhythmic should be applied. Hope to have been helpful to you. Greetings!
