It is a type of **ectopic beat**, meaning it comes from an \u201cextra\u201d electrical focus rather than the heart\u2019s usual pacemaker. PVC is frequently discussed in cardiology because it can be felt as palpitations and can appear on routine heart rhythm testing. Clinicians use the term PVC in ECG interpretation, ambulatory monitoring reports, and arrhythmia evaluations."}
