What is a Preventricular Contraction??
It’s called a premature ventricular contraction, or PVC, and it happens a lot when there is a fluid electrolyte imbalance in your body. What happens is the ventricle will contract before it is supposed to and push the remaining blood that is in that ventricle to the atria. Your heart is controlled by electrical impulses(that’s what an ECG measures, electrical impulses), and when part of your electrical system in the heart “fires” before it is supposed to, you get what’s called a PVC.
