Finding	Clinical significance
Weak pulses	Poor cardiac output (e.g., aortic stenosis)
Bounding pulses	High cardiac output (e.g., patent ductus arteriosus)
Single second heart sound	Often cyanotic heart disease (e.g., truncus arteriosus, hypoplastic left heart)
Holosystolic, continuous, harsh murmur	Pathologic
Grade 3 or higher murmur	Pathologic
Diastolic murmur	Pathologic
Hepatomegaly	Left heart failure
