Ventricular Septal Defect (VSD) Congenital

Hypertrophic Obstructive Cardiomyopathy (HOCM)

Auscultation of a diastolic sound referred to as tumor plop, resulting from a left atrial myxoma. The sound arises from obstruction to ventricular in-flow. Copyright 2011 by the Texas Heart Institute at St. Luke's Episcopal Hospital.

Tumor Plop (Left Atrial Myxoma)

The early diastolic sound of pericardial constriction occurs slightly earlier than the average third heart sound. Its frequency is somewhat higher, allowing you to hear it throughout the precordium using the diaphragm and the bell. Common causes of pericardial constriction include prior cardiac surgery and uremic pericarditis. Copyright 2011 by the Texas Heart Institute at St. Luke's Episcopal Hospital.

Pericardial Knock (Constrictive Pericarditis)

Auscultation of the fixed splitting of the second heart sound, a finding on physical examination very specific for atrial septal defect. Copyright 2010 by the Texas Heart Institute at St. Luke's Episcopal Hospital.

Fixed Splitting of the Second Sound (ASD)

Wide Splitting of the Second Heart Sound (RBBB)

Paradoxical Splitting of the Second Heart Sound
