Accentuating systolic aortic regurgitation during premature ventricular systole

A 47-year old male patient with chest pain during deep inspiration was admitted to our hospital. He had no dyspnea or history of heart disease. His blood pressure was 90/60 mm Hg, and he had infrequent extra beats during examination. The patient was unaware regarding these beats, and his physical examination was otherwise normal. Electrocardiography showed a sinus rhythm with ventricular premature systoles that probably originated from the left ventricle (LV) outflow tract (Fig. 1). Transthoracic echocardiography revealed normal LV diameters and systolic functions with mild mitral and barely visible aortic regurgitations (ARs)
