I have been having something going on with my heart for about the past 3-4 weeks.  It beats unusually hard, not necessarily any faster, but just out of my chest feeling at times.  And at certain times it feels irregular like one beat will be super strong and then the next 2 or so not very strong.  I have been under quite a bit of stress lately, and figured that may be it.  But even on vacation it did not subside.  Any idea of possible things this could be ?
Hello there. I read your question and understand you are having palpitations and irregular heart rate that is arrhythmia. It needs to be investigated. Stress may be a probable cause, but I would advise you to get an EKG and 24 hours Holder done to rule out any underlying heart disease. I hope that answers your question. If you have any other questions please feel free to write.
