Cardiology Flashcards
Medication contraindicated in WPW
Digoxin
(If block AV node, encourage accessory pathway)
What medication do not give in atrial flutter
Fleicanide
(May get 1:1 flutter)
Mild aortic stenosis
<40mmHg
Moderate aortic stenosis
40-70mmHg
Severe aortic stenosis
> 70mmHg
Severe pulmonary stenosis
> 70mmHg
Qp:Qs
AMVAP
Ao - MV
—————
PV - PA
ASD cardiac cath
Sats: increased RA, RV, PA
Pressure: increased RA, RV, PA
Large VSD cardiac cath
Sats: increased RV, PA
Pressure: increased RA, RV, PA, LA
PDA prem vs term
Closure rare in term infants and indomethacin not effective
Which VSDs may spontaneously close
Perimembranous
Muscular
ASDs that rarely close spontaneously
> 8mm
A2 and P2 widely split
Pulmonary stenosis
Peripheral pulmonary stenosis murmur
Midsystolic pulmonary valve area
Transmitted to axilla and back
MAP in coarctation of aorta
15-20mmHg greater in UL than LL
Pressure gradient severe mitral stenosis
31mmHg
Coarctation of aorta murmur best heard
Posteriorly (think left interscapular)
S2 single and loud
S3 gallop usually present
Mitral regurg murmur
Regurg systolic murmur apex
Mitral regurg heart sounds
S2 may split widely
S3 commonly present and loud
Mitral valve prolapse murmur
Mid systolic click with or without late systolic murmur
Timing of arterial switch for TGA
1-2 weeks of life
Duct dependent lesions
R heart obstruction: Critical PS, PA with IVS, Ebstein
Left heart obstruction: Critical AS, Critical CoA, interrupted aortic arch, HLHS
Mixing: TGA
CHD with early cyanosis
Tricuspid atresia
Ebstein
TGA
Causes of differential cyanosis
CHD: Critical AS, Critical CoA, interrupted aortic arch
PPHN
WPW frequent association and predisposes pts to SVT
Ebstein anomaly
Which lead are Q waves pathological in?
