What does the abbreviation PVC stand for in cardiology?

In cardiology, the abbreviation PVC stands for Premature Ventricular Contraction. This term describes an early heartbeat that originates in the ventricles of the heart, disrupting the normal heart rhythm. PVCs can occur occasionally in many individuals and are often benign, especially in healthy people. They may be felt as a fluttering sensation in the chest or skipped beats.

Understanding the term is crucial as PVCs can indicate various underlying conditions, ranging from a healthy heart reacting to stress or stimulants to potential cardiac issues that may require further evaluation. Awareness of PVCs is important for medical professionals in their assessments and management of patients experiencing irregular heart rhythms.

The other suggested options do not accurately describe PVCs or their related conditions in cardiology, underscoring the importance of using the correct terminology in medical settings.
