Suggest Treatment For Irregular Heart Rate And Shortness Of Breath

Sometimes I feel like my heart stopped beating for 1 or 2 seconds and I often feel my chest tighten and breathing became very hard for me. I'm short breathed, I haven't been exercise for over 2 years. Sometimes I wake up feeling dizzy/light headed and I would see dots for a short period of time. When I'm dizzy/light headed, my whole body feels numb and heavy, I feel like I'll faint or about to die if I don't lie down. My hearing became very bad as if I was under water or there was a loud bang next to my ear.
