It doesnt happen very often, but it happens enough for me to question it. I can feel a while off that im going to faint. I come out in an ice cold sweat, and im dripping wet. I have to sit down for a while and sometimes i feel like Im going to pass out. Now i ve noticed that out of the blue my heart starts beating really fast for about 3 beats even when Im relaxed and then it just returns to normal. It s been happening a few times a day for the past week. Is it anything to be worried about? Candice
