My father-in-law has been in the hospital recently with irregular heartbeat. His doctor said that having an icy feeling in his chest is a symptom of this. During his last stay a couple of weeks ago in the hospital, his heart went back into rhythm on its own. I just checked his heartbeat and it felt irregular to me. It was about 99 bmp. Is this something we need to see a doctor immediately for?
Hello, Regarding your concern, I would explain that his symptoms could be related to paroxysmal atrial flutter.  For this reason, I recommend bringing him to the ER for a physical exam and a resting ECG.  Hope I have answered your query. Let me know if I can assist you further.
