I’ve been having some lightheadedness with my PVC’s, and I passed out once. What should I do?
Lightheadedness or fainting needs to be evaluated. It is very possible that this is not caused by your PVCs, but it should definitely be checked out.
Take a look at this blog for more information and links:
What are the causes of ventricular arrhythmias, VT, Bigeminy and Trigeminy?
Lightheadedness whatever the cause, is the result of insufficient blood flow to your brain. During some arrhythmias, the heart becomes less efficient and pumps less blood into your circulation. Since your brain is more sensitive to changes in blood supply than all your other organs, it will let you know with symptoms that may range from lightheadedness, to losing your conscience.
Hope this helps,
