I just got my pacemaker last week. I have had afib for years,three ablasions, etc. I was on xaralto until 3 days before my surgery/pacemaker. Now I am on one baby aspirin until tues recheck. They think they nicked something as there was a tiny bit of fluid around my heart. Expected to self resolve as not pain and small amount. My questions are many? But the first one is how to do you know if you have a DVT or PE? I imagine a PE to be radical symptoms but not sure.
