The word "PVC" can refer to two different things, and I'll explain both of them clearly for you.
Meaning: In a medical context, "PVC" stands for "Premature Ventricular Contraction." This is a term used to describe an irregular heartbeat. It happens when the heart's lower chambers (ventricles) contract earlier than they should, which can lead to an unusual heartbeat pattern.
Meaning: In a materials context, "PVC" stands for "Polyvinyl Chloride." This is a type of plastic that is often used instead of rubber or other materials in products like electrical cables, pipes, and flooring.
There are no specific idioms or phrasal verbs directly related to "PVC," but you might come across phrases like "to contract" in medical contexts, which means to tighten or shorten.
In summary, "PVC" can mean either a medical term referring to an irregular heartbeat or a type of plastic commonly used in various products.
