Question:
components of S2 (A2, and P2) fuse into a single sound.
Answer:
During expiration
Question:
What causes a split S2?
Answer:
During inspiration, the right heart filling time is increased, which increases right ventricular stroke volume and the duration of right ventricular ejection compared with the neighboring left ventricle. This delays the closure of the pulmonic valve, P2, splitting S2 into its two audible components.

Question:
what causes paradoxial splitting of a2
Answer:
LBBB. aortic stenosis with paradoxal splitting present on expiration and disappears on inspiration
Question:
splitting of the second heart sound. At what area on the patient's chest would the student have the best opportunity of hearing this sound?
Answer:
Pulmonic valve: 2nd & 3rd intercostal space
Question:
the second heart sound is split and fixed on both inspiration and expiration
Answer:
Fixed splitting of the second heart sound occurs in atrial septal defects and right heart failure and does not vary with respiration.

Question:
QRS complex
Answer:
the duration of ventricular depolarization and is normally less than 100 milliseconds.
Question:
P wave
Answer:
the result of atrial depolarization
Question:
T wave
Answer:
result of ventricular repolarization
Question:
S3 corresponds to
Answer:
abrupt deceleration of inflow across the mitral valve 3 / 4
Question:
S4 corresponds to
Answer:
increased left ventricular end diastolic stiffness which decreases compliance
Question:
systole; diastole
Answer:
systole: S1: ventricular contraction/semilunar valves open (pulmonic and aortic) and av valves closed (mitral and tricuspid) diastole: S2: ventricular relaxation "die"/av valves open (mitral and tricuspid) and semilunar closed (pulmonic and aortic)
Question:
Conductive hearing loss
Answer:
external and middle ear
Rhine test: bone condition lasts longer or equal to air conduction
Weber test/ Hum test: sound lateralized to impaired ear
