Heart Murmurs
- Right-sided heart murmurs increase in intensity during inspiration.
- HCM murmurs increase in intensity with Valsalva maneuver and on standing from a squatting position.
- MVP clicks move closer to S1, and the murmur lengthens with Valsalva and on standing from a squatting position.
- Fixed splitting occurs with RBBB, pulmonary valve stenosis, VSD, and ASD (both with left-to-right shunts).
- Paradoxical splitting (split S2 with expiration) occurs with LBBB, HCM, and severe AS.
- Innocent heart murmurs are midsystolic, located at the base of the heart, grade 1/6 to 2/6 without radiation, and associated with normal splitting of S2.
- Signs of possible significant cardiac disease include an S4, murmur grade ≥3/6 intensity, any diastolic murmur, continuous murmurs, and abnormal splitting of S2.
