a double systolic peak

bisferiens pulse

causes of bisferiens pulse

1. pure aortic regurgitation


2. combined aortic stenosis and regurgitation


3. hypertrophic cardiomyopathy



regular rhythms characterized by changes in amplitude from beat to beat

pulsus alternans

causes of pulsus alternans

left ventricular failure (usually accompanied by an s3 sound on the left)

Regular, irregular rhythm (one normal beat followed by a premature contraction).Alternates in amplitude (one strong pulse followed by a quick, weaker one)

Bigeminal pulse

Cause of bigeminal pulse

premature ventricular contractions

Paradoxical pulse characteristics

1. Palpable decrease in pulse amplitude on quiet inspiration


2. Pulse becomes stronger with expiration


3. You may need a sphygmomanometer to detect the change (the systolic pressure will decrease by more than 10 mmHg during inspiration)

Causes of paradoxical pulse

• Pericardial tamponade


• Constrictive pericarditis


• Obstructive lung disease
