Atrial Contractions

emdagenais asked:


Can the cells in the heart that help it contract when the natural pacmaker (sino atrial node?) is inefficent be the cause of a more forceful beat(Palpitations?). I have had bradycardia 39bpm for the past ten months, which I think has caused imbalance and the forceful beat of the heart, that is most noticeable laying down in bed. Wondering if when the heart has to take up the slack for the pacemaker, that is why i feel a much harder contraction. Very worried, to this point the cardiologist has found nothing from the ecg, echo, blood test, and holter. Now that want to send me to neurology(????). Any insight into the question is appreciated.
I have not had a pacemaker put in.

For a while I have been feeling what I think are irregular heartbeats occasionally. The feeling is hard to explain but it kind of feels like my heart beats really hard 1 to 3 times and then it’s normal. I did a little research and found that this could be premature atrial contractions or premature ventricular contractions(PVCs). The reason I think it could be these is because of this quote I read “In some people, it can be related to stress, too much caffeine or nicotine, or too much exercise” I am sometimes pretty stressed out, I often smoke too many cigarettes, and sometimes I take this pre-workout drink which has a lot of caffeine for working out early in the morning. I definitely work out too much but I don’t drink coffee and I only take the workout drink maybe once out of every 7 times I work out.

These possible extra heartbeats don’t necessarily feel bad in any way, if anything they make me feel like I need an extra breath. Should I see a doctor? These occurrences are pretty uncommon.
Thank you for your time and your responses.
