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 |
