What causes the S1 heart sound?
Cardiac apex
Where is S1 best heard?
S1
What heart sound aligns best with the QRS?
Aortic and pulmonic closure
What causes the S2 heart sound?
Cardiac base
Where is S2 best heard?
S2
What heart sound best aligns with the T wave on ECG?
False (may be normal)
True or false: a split S1 is always pathologic in large breed dogs
Delayed closure of either aortic or pulmonic valves
What generally causes S2 to be split?
L or R bundle branch block, pulmonary hypertension, ASD
What specific diseases cause a split S2?
Cattle, horses
In what animals can S3 or S4 be a normal heart sound?
TrueTrue or false: an S3 or S4 gallop is always associated with disease when heard in cats and dogsCHF presentWhen are S3 or S4 sounds called a gallop in large animals?Abrupt end of rapid ventricular fillingWhat causes the S3 sound?DCM, CHF, dilated, hypocontractile heartWhat diseases is an S3 heart sound associated with?S3 gallopWhat is this heart sound?Contraction of atria into stiff or hypertrophied LVWhat causes the S4 sound?HCMWhat diseases is an S4 sound associated with in cats and dogs?S4 gallopWhat is this heart sound?Mitral or tricuspid valve diseaseWhat diseases is a mid systolic click associated with?Valve prolapses into atrium then tensesWhat causes the midsystolic clicking noise in mitral or tricuspid valve disease?Midsystolic clickWhat is this heart sound if the shorter line is sharp sounding?Turbulent blood flow in heart and great vesselsWhat generally causes murmurs?PhysiologicWhich are generally softer murmurs: physiologic or pathologic?Systolic, diastolic, continuousWhat are the 3 general classifications of murmurs based on timing within the cardiac cycle?Systolic murmurWhat is this heart sound based on timing in the cardiac cycle?Diastolic murmurWhat is this heart sound based on timing in the cardiac cycle?Continuous murmurWhat is this heart sound based on timing in the cardiac cycle?Present after 1-2 minutes listening in quiet room with compliant animalWhat classifies a grade I/VI murmur?Soft murmur noted soon after beginning auscultationWhat classifies a grade II/VI murmur?Medium intensity murmurWhat classifies a grade III/VI murmur?Loud murmur without thrillWhat classifies a grade IV/VI murmur?Loud murmur with thrillWhat classifies a grade V/VI murmur?Loud murmur with thrill, heard when stethoscope removed from chest wallWhat classified a grade VI/VI murmur?Regurgitant quality, ejection qualityWhat are the 2 ways systolic murmur sounds can be described?Holosystolic regurgitant qualityWhat type of systolic murmur is this?Mitral or tricuspid regurgWhat diseases is a regurgitant quality murmur associated with?Ejection quality (also called crescendo decrescendo murmurs)What type of systolic murmur is this?Ejection qualityWhich is usually harsher in sound: regurgitant quality or ejection quality systolic murmurs?Stenosis of aortic or pulmonic valveWhat diseases is an ejection quality systolic murmur associated with?False (may be innocent, especially if low grade and low frequency)True or false: diastolic murmurs are always pathogenic in horsesAortic regurg, sometimes pulmonic regurg with PHTWhat diseases are diastolic decrescendo murmurs associated with?PDA, sometime other arteriovenous fistulasWhat diseases is a continuous murmur associated with?Very high in axilla at L heart baseWhere is a PDA murmur best heard?To and Fro murmurWhat type of murmur is this?Very short break between systolic and diastolic murmursHow can you tell a to and fro murmur from a continuous murmur?Stenotic valve that also has regurgWhat is a to and fro murmur associated with?DiastolicWhich is usually softer in a to and fro murmur: systolic or diastolic sound?
