Base Right
Base Sound
Patient has a normal heart with mild anemia. The heart is
hyperdynamic and has elevated cardiac output. S2 is accentuated
at the base.
Fixed Split S2
Patient has an atrial septal defect which increases flow through the
right heart, prolongs RV systole and also produces a mid-systolic
murmur (MSM) because of increased flow through the RV outflow
tract.
Base Left
Physiological Split
S2
The splitting of S2 is easily heard during inspiration and the second
sound is single during expiration. The second component of the
split sound (P2) is accentuated.
Split S2
S2 is variably split during mid-inspiration, as three beats are
repeated.
Left Side Sternal
Border
Paradoxical Split
S2
The splitting of S2 is heard during expiration, but the sound
becomes single during inspiration.(The background noise is
increased during inspiration.)
Opening Snap
Patient has mitral stenosis, responsible for an early crisp diastolic
sound heard at the base 0.08 seconds after S2. S1 is usually loud at
the base, which reflects mitral stenosis.
Friction Rub
Patient has uremic pericarditis, which leads to rubbing of
roughened visceral and parietal pericardial surfaces against one
another. The 3 component rub exists during deep inspiration.
3. Locate the small stereo jack on the bell and
