No, I don't mean PVC pipes. I think most people are aware of PVC pipes. If they aren't, then they have bigger issues.
I mean Premature Ventricular Contractions. It sounds scary and dangerous, but they're not. However, when I kept getting them and didn't know what they were, I was freaking out pretty good. So, I want to let people know what they are and kind of what they feel like, so they can see if this is what they've been experiencing for themselves.
WARNING: I am not a doctor despite watching House, MD a second time though and working in a doctor's office and have done classes in Anatomy/Physiology and Medical Terminology. I still got checked out by a doctor just to make sure what I had wasn't more serious and if you're really concerned then I suggest you do the same. Okay, moving on...
This is your heart. The ventricles are the two lower chambers, and end up being responsible for pumping the blood to your lungs for oxygenation and to the rest of your body. There are nodes (not pictured) that control your heartbeat via electrical impulses. The main one is the sinoatrial node, but the purkinje fibers control the contraction of your ventricles. When they are out of sync, a PVC occurs.
i just had a PVC the other day when I was laying down for bed, and I noticed something interesting. I put my fingers on my neck in order to feel my heartbeat, and every time the ventricles pumped too early (as in, they didn't allow the cavities to be filled with blood before going off), I did not get a heartbeat on my neck. It feels a lot like a skipped beat or an extra beat. You are hyper aware of your pounding heart, and it almost seems like it's bouncing around in your chest. For me, a PVC lasts maybe 30 seconds, but it seems like a very long time. I suppose they could become dangerous if they continued due to the simple fact that the heart isn't pumping blood very efficiently; eventually that would cause serious issues.
However, I read that there is a way to stop them from continuing:
That's right. Even if it's a fake yawn. I read that the act of yawning uses the same vegus nerves as the heart, or something like that (I can't seem to find the article now. I don't think doctors know officially how it works) and it kind of resets the heart rhythm. i don't know why it works, I just know that it does!
I've done so many of these "Raising Awareness" posts that I think I'm going to re-link them in case anyone is interested in reading all the other lame things wrong with me!
