Hey guys.
The past few days i've been feeling slightly out of breath, it usually begins in early evening or when i go to bed, and i've also been getting palpitations. It wasn't really bothering me until tonight when i was sitting here at the computer and had a really bad palpitation. It just felt as though my heart stopped and then started again, and in between for a split second it felt as though i couldn't breath. I got up and felt really dizzy and so had a glass of water and sat down on the floor against the wall to try and calm myself down. Then when i stood up i got a slight pain on the left side of my chest. I've calmed down a bit now and the pain has gone away, but i'm still really worried its something serious. My heart BPM is 89 at the moment. Is this normal? (given i am slightly wound up) Thanks.
