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, but it is also possible that this is not caused by your PVCs. A number of blood and other tests are necessary to evaluate this.
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 around your body. 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,
