I have had two discrete Afib episodes, 11 years apart, the last one was 5 years ago. The cardiologist I saw then said he was comfortable with my taking a blood thinner for 5 days after an episode if I had another one, but agreed that a daily dose was not necessary. Both of my episodes came after a particularly stressful event. I do get PACs and PVCs and after wearing a Zio patch (that I could only tolerate for a few days) I was told that I have SVT (supraventricular tachycardia) which seems to run in my family. Those episodes last an average of 10 seconds so not anything major. I’m 73 now (female) and have been taking 25 mg metoprolol XR and 25 mg losartan since my first afib episode. However, I’m able to get away with taking half of the metoprolol for the most part. I’m pretty reactive to medications.
