This is considered borderline. Discuss with the patients cardiologist or Dr who prescribed the testing to see how this fits in the scope of the patients medical history, symptoms, previous tests and medications.

A PVC coupling interval of less than 300 ms is concerning because the PVC may occur on the T wave provoking ventricular tachycardia or fatal ventricular fibrillation, especially in the presence of structural cardiac disease. Fortunately, you're not within these parameters.
