First off: got the news today that I am still PCRU; that makes 2.5 years. We missed the 2 year PCR test, so I was very curious to know whether I had hit this important statistical milestone.
That said, on Christmas Eve I developed atrial fibrillation with rapid ventricular response. This is the second time since February (trigged both by hitting my back against the bed; I was playing with my baby this time when it happened). They electro cardioverted me and I walked out 30 minutes later, but it was scary because I was having moments of faint feeling. Last time I had low potassium, this time my electrolytes came back fine.
Anyway, since I have been on Tasigna (300mg 2x daily), I have had an increase in PVCs, especially during workouts. I have also had a quickened resting heart rate above 100, for which I now take low-dose beta blocker. I have had two full-blown episodes of atrial fibrillation, some what I think are PACs (because they feel like PVCs except without the hard thud), and what I think are sporadic moments of atrial flutter. I didn't have anything like this pre-Tasigna, except the occasional PVC once every few months.
Is there a way to know if this is Tasigna related, or more underlying heart problems? I am only 27, and have had good EKGs and a good echocardiogram outside of this. I can exercise without any problems aside from PVCs. If there is no way, I'm thinking about talking to my onc and seeing if we could try a half dose, since I've been 2.5 years PCRU.
Thanks for any advice!
