Heart Flashcards
heart sounds to be evaluated
- S1, S2
- S3
- S4
- Murmurs
- Between S1 & S2
- ventricular contraction - Flow across pulmonic and aortic valves.
Systole: (Ejection)
- Between S2 & S1. -
- Ventricular relaxation -
- Flow across bicuspid & tricuspid valve
Diastole (Filling)
Thrills represent a
palpable murmur
reasons for performing left lateral heart auscultation
- S3 & S4 more detectable
- Certain murmurs detectable (Mitral Stenosis)
- PMI is louder
Closure of the Aortic & Pulmonic valves create
S2
Closure of mitral and tricuspin valves creat
S1
Pulmonic valve (P2) closes slightly
after the aortic valve (A2) during
inspiration, which causes…
Splitting S2
Comes just after S2 (similar to S2 split)
S3
Ventricular gallop
S3
Just prior to S1
(aka: Atrial Gallop
S4
- Usually not normal
- Active Ventricle filling
- Possible Hypertension
S4
Murmurs-Aortic Stenosis, high-pitched, blow, best heard at…
aortic area
Murmurs-Mitral Stenosis low pitched, diastolic, best heart at…
apex in lateral decubtitus position
Murmurs-Mitral Regurgitation
High-pitched, harsh, blowing, systolic
apex
