1

Systolic crescendo-decrescendo murmur with radiation to carotid arteries

Aortic Stenosis

Best heard at 2nd intercostal space

 

2

Aortic Stenosis (AS)

A2 decreased

Ejection click and S4 heard at apex

Paradoxical S2 split

Narrow pulse pressure, delayed cardiac upstroke, LVH with lift at apex

3

Diastolic decrescendo murmur

Heard best at left lower sternal border 3rd and 4th interspace

Aortic Insufficiency (AI)

4

Aortic Insufficiency (AI)

Often w/ LVH, widened pulse pressure

S3 and pulsus alternans present w/ acute AI

Traube sign, Quincke sign, Corrigan pulse

5

Systolic crescendo-decrescendo murmur

Louder with inspiration

Pulmonic stenosis (PS)

Click often present

6

Pulmonic Stenosis (PS)

Heard best at left 2nd intercostal space

P2 delayed and soft if severe

Right ventricular hypertrophy (RVH) with parasternal lift

7

Diastolic decrescendo murmur

Left 2nd intercostal space

Pulmonic Insufficiency (PI)

8

Pulmonic Insufficiency (PI)

Louder with inspiration

RVH usually present

9

Diastolic Murmur

Opening snap best heard at apex

Mitral Stenosis (MS)

Localized at the apex

10

Mitral Stenosis (MS)

Increased P2

Right-sided S4

Left-sided S3 often present

RVH with parasternal lift may be present

11

Holosystolic murmur with radiation to the axilla

Mitral Insufficiency (MI)

12

Mitral Insufficiency (MI)

Heard best at apex

Soft S1, possibly masked by murmur

S3

LVH

Midsystolic click suggests mitral valve prolapse

13

Holosystolic murmur

Increases with inspiration

Tricuspid Insufficiency (TI)

Heard best at left lower sternal border

14

Tricuspid Insufficiency (TI)

Right-sided S3

Large V wave in jugular venous pulsations

15

Systolic murmur

Fixed splitting of S2 and RVH

Often with left and right sided S4

Atrial Septal Defect (ASD)

Heard best at left upper sternal border

16

Harsh Holosystolic murmur

Ventricular Septal Defect (VSD)

Heard best at left lower sternal border

S1 and S2 may be soft

17

Continuous machinery murmur

Increased P2 and ejection click

Patent ductus arteriosus (PDA)

Heard best at left 1st and 2nd intercostal space

Increased P2 and ejection click may be present

18

Early diastolic sound caused by rapid ventricular filling

S3

Left side heard at apex

Right side heard at left lower sternal border

19

S3 usually found with:

Young people

Pregnancy

Thyrotoxicosis

Mitral regurgitation

Congestive heart failure

20

Late diastolic sound caused by a noncompliant ventricle

S4

Left side heard at apex

Right side heard at left lower sternal border

21

S4 found with - both right and left side:

Right side

-pulmonic stenosis

-pulmonary hypertension

Left side

-HTN

-aortic stenosis

-myocardial infarct
