I have had Supraventricular Tachycardia for many years. At first it was scary but once I was diagnosed and did some reading about it, it became just an annoyance. I am on 25 mg Atenelol 2x a day. The last couple years, I have experienced episodes that are very different...palpitations that can last from 1 min to an hour. Lately they have been happening every day. My doctor had me wear a Holter Monitor (which I have done many times over the years) but this time my doctor said I have something that is very rare Bigeminy and Trigeminy. Because I have had SVT for so many years, I am not easily scared by heart arrhythmia's so I would be the kind that would ignore it and just deal with it. However, as I have been reading about it, I realize it is something that must be checked out because there can be underlying causes. I will be going to my cardiologist for tests in a couple of weeks. Arrhythmia here and there for a few seconds or a flutter now and then is no big deal but if it goes on and on and is frequently happening...get it checked!
What do you mean 8-9 within an 8 hour period? 8-9 episodes of fast heart rate or 8-9 skipped beats? Just because your sister has afib doesn't necessarily mean you will get it. It isn't a hereditary thing. There are other factors more lifestyle related that can go into its cause though I am not totally sure doctors know exactly why someone gets it but it isn't necessarily hereditary but if you are having severe chest pains you really should be checked out by a doctor asap. Make an appointment and get your heart checked. Take care and feel better soon.
