My husband is 44 year old and is lightheaded when he layed down for bed. He said is heart seems to be skipping beats and his breath feels different. He will not let me call 911 nor will he go to the ER. He did agree to see a doctor on Tuesday morning before work. How concerned should I be? He said the symptoms is gone now. Heart problems run high in both sides of his family.
Hereafter going through the medical details provided by you, I would like to tell you that as of now there is nothing emergency or serious thing to worry about. Probably he had experienced few ectopic. Cut down his coffee intake or any other Chat Doctor.  Smoking should be completely stopped if he smokes.However, as there is a strong family history of heart disease then it's highly advisable for him to go for a basic cardiac check up which should include an ECG, ECHO and a TMT. Kind Regards
