Murmur Maneuvers Flashcards
Hand grip
Increases systemic vascular resistance. Increases intensity of MR, AR, VSD; decreases intensity of AS, hypertrophic cardiomyopathy murmurs. For mitral valve prolapse, increases murmur intensity and delays onset of click.
Inspiration
Increases intensity of right heart sounds (increased filling)
Valsalva and standing
Decreases venous return. Decrease intensity of most murmurs except in hypertrophic cardiomyopathy (murmur increases). Decreases murmur intensity for MVP and makes click earlier.
Rapid squatting
Increases venous return, increases preload, increases afterload with prolonged squatting. Decreases intensity of hypertrophic cardiomyopathy murmur, increases intensity of AS murmur. Increases intensity of MVP murmur and delays click.
Systolic heart sounds
Aortic/pulmonic stenosis, mitral/tricuspid regurg, VSD
Diastolic heart sounds
Aortic/pulmonic regurg, mitral/tricuspid stenosis
