Heart Flutters Questions

To anyone who has experienced this,

What exactly causes heart flutters/palpitations? I'm only 18 and they have been coming and going since last August of 2013. I've had 2 doctors visits both with EKGs, and on the second one, my heart did it for it... but the doctor didn't have much to say about it. I'm just not sure if this is something I should be concerned about or my anxiety issues + OCD over this is just playing tricks on me. Sometimes when it happens, I freak out so bad and then when it doesn't happen, I just keep thinking and worrying about them happening again.

If they come and go one in a while, some coming a LOT and lasting for a whole day, can it just be anxiety? But if they happen sometimes bending down or going up the stairs, what is that if it's not anxiety?

They don't hurt when they happen. It just feels like a hiccup in my chest, where it first skips a beat and then pounds hard. I instantly freak out. There's no chest pain or shortness of breath, really, unless it turns into a panic attack. I'm not sure if I need to schedule a cardiologist appointment, because at the moment, they aren't happening. I've kept a log of when it happens and it fluctuates, so if I went and my heart wasn't doing it at the time, would it be worth it?

I get them all the time have for 10 plus years. My husband/ friends/sister gets them. It happens. Like I said it caused by stress, anxiety, caffeine, lack of sleep, hot weather, you name it. Your fine. hugs.,

I echo the comments of the others. I've had the flutters, "skipped beats", etc. for years. After multiple EKGs, blood work, 2 holter monitors, and 2 stress tests, it was more than confirmed that it was just anxiety/stress. Although they can be scary and even very frequent, they are harmless and you can rest assured there is nothing to worry about.
