I wake up in the middle of the night , with a jerk, heart racing , body weak, i literally have to wait about 5-10 seconds for my heart rate to slow and body to almost become normal. afterwards my chest aches from the incident. should i be worried?

Any issue involving the heart should be assessed by a doctor. An EKG or 24 hour Holter ( heart monitor will assess hear rate while sleeping for correlation. This may be autonomic dysfunction , reflux, anxiety , sleep apnea. F/U/W/ MD

i would not be overly worried from a cardiac standpoint. generally speaking this sounds like a normal issue. discuss with your pmd
