I had my medtronic PM for more than 6 years and no issues so far.Sometime when I send my transmission they used to tell me about an episdoe of A-fib for few seconds or mins but my EP said he doesnt see the need to put me on blood thinners. During my last check up they noticed a ventricular tachycardia rythm and he ordered an ECHO and MRI. The echo showed my EF dropped to 45% and MRI is scheduled mid-March. He also mentioned that they could replace my PM to an ICD to manage these rythms. Just wondering if anyone has gone through a similar experience. I am 46 male living in Dallas TX.
