How many PVCs per minute is considered pathological?

• A. 4 or more
• B. 5 or more
• C. 6 or more
• D. 7 or more

Answer: (C)

Pathological PVCs (Premature Ventricular Contractions) are defined based on their frequency, which can provide insights into the underlying cardiac condition. Typically, experiencing six or more PVCs per minute is regarded as pathological because this level of increased ectopic activity may indicate underlying structural or electrical heart issues, such as ischemia or myocardial dysfunction. The significance of this threshold lies in its association with a higher risk of more severe cardiac events, including arrhythmias.

When considering the provided options, a frequency of less than six PVCs may not significantly impact hemodynamics or warrant immediate clinical concern, while the threshold of six or more underscores a need for further evaluation and monitoring. It’s crucial for practitioners to recognize this cutoff for timely and appropriate management of patients with potential cardiovascular risks.
