I have been experiencing some weird heart beating issues. Basically, this year my heart began to beat irregularly(i.e. my heart enters a state where it kind of tenses up for a few seconds, there is no pain involved in my heart or around the area). I am kind of at a loss for words to effectively describe this issues so I apologize for any lack of clarity. Should I be worried? Anyone happen to be familiar/experience with this phenomena? I look forward to replies regardless of what is mentioned in the OP.
