Hi I’m a male 19 yrs old and I suddenly

Patient: Hi I’m a male 19 yrs. old and I suddenly the last couple of days noticed that I’m having shortness of breath.. When I try to go to sleep I lay down. Close my eyes and then about 2 – 5 min. Later while my eyes are closed feel like I’m getting dizzy and want to pass out.. That happens for about an hour and then I finally fall asleep. Then today I’ve gotten dizzy while sitting down out of nowhere. Also when I am about to fall asleep my pulse is around 45bpm.. Also I have felt a weird sensation in my heart area like it flutters or something.. Do you see a problem at all?
