PS or SAS

Decreased Inotropy

MMVD or endocarditis

Increased afterload

Dilated Cardiomyopathy (DCM)

Decreased lusitropy

Increases preload

Systemic or pulmonary hypertension

HCM or Pericardial effusion w/ tamponade

PDA, VSD or mitral or tricuspid defect

Concentric hypertrophy appears as an increased wall thickness and small chamber

What is associated with this abnormality?

• Pressure overload disease

• Volume overload disease

Eccentric hypertrophy appears as a normal wall thickness with a dilated chamber.

What is associated with this abnormality?

• Pressure overload disease

• Volume overload disease

Match the following:

• palpation of the chest wall

• Precordial thrill

• HCM "ba-lub-dub"

  Basilar

• S4 gallop

• DCM "lub-dub-ah"

  Apical

• Precordium

• ability to feel vibrations of a murmur

• S3 gallop

What is the first grade of heart murmur where a precordial thrill is noted

What are the 4 components that are associated with heart murmur descriptions

Answer explanation

Grade (1-6)

Location = loft or right + apex or base

Timing (systolic, diastolic or continuous)

Quality

A heart murmur that is classified as continuous is specific for what?

What 3 features are used to evaluate arterial pulses?

Answer explanation

Strength- palpable pulse pressure (difference between the systolic and diastolic blood pressures)

• - normokinetic (adequate, strong)

• - Hypokinetic (weak, thready)

• - Hyperkinetic (bounding, water hammer)

• Synchronous- hearing the heartbeat that is almost immediately followed by a palpable pulse

• Symmetrical- right and left arterial pulses are the same strength
