Overview

Complete physical examination help determine any heart defects as a cause for premature ventricular contractions.

Physical Examination

A physical examination should be conducted after a full history has been taken. This is useful in determining any possible heart defects that might be causing the palpitations. For example, some cases of premature ventricular contraction have a mitral-valve prolapse which can be determined through the physical examination

• An auscultated fully compensatory pause is present with most premature ventricular contraction and is identified by the prolonged pause following the premature beat.
• Atrioventricular dissociation if present will result in variable intensity of the first heart sound secondary to a changing PR interval.
• A cannon "A" waves due to simultaneous retrograde atrial and antegrade ventricular activation may be observed while examing JVP.
• Patients with heart disease may show a variation in the intensity and timing of their cardiac murmurs when they have PVCs.
