(Definition of âpedalâ from the Cambridge Advanced Learner's Dictionary & Thesaurus Â© Cambridge University Press) âpedalâ in American English See all translations
Syncope, also known as fainting, passing out and swooning, is defined as a short loss of consciousness and muscle strength, characterized by a fast onset, short duration, and spontaneous recovery. It is due to a decrease in blood flow to the entire brain usually from low blood pressure.
This leads the blood vessels in your legs to widen, allowing excess blood to collect in your legs, which lowers your blood pressure. As a result, thereâs a sudden drop in blood flow to your brain, and that's what causes you to pass out. This kind of fainting is normally not a sign of something serious.
