Cardiology Flashcards
Still’s murmur increased by…
supine, fever, exercise
VSD murmur
holosystolic
Most common type of ASD
secondum ASD
PE in ASD
split fixed S2, SEM in the pulmonary area
Complete AVCD
primum ASD and inlet VSD
Cyanotic CHD
TA, TGA, tricuspid atresia, TOF, TAPVR
Symptoms of ASD
most likely asymptomatic
Reason for fixed split S2
volume loading of the right ventricle (normally occurs during inspiration due to increased venous return)
EKG findings in ASD
RSR’ in V1
EKG findings in AVCD
left axis deviation
Most common cause of cyanotic CHD
TOF
TOF murmur
harsh SEM and LUSB w/ radiation to back (may disappear during tet spell)
TOF x-ray
boot-shaped
Most common form of cyanotic CHD diagnosed in the neonate
TGA
TGA x-ray
egg on a string
TAPVR x-ray
snowman
Obstructive TAPVR
supracardiac, infracardiac
Obstructive left-sided lesions
critical AS, coarctation, HLHS
Ebstein’s anomaly arrhythmia
WPW (50%) - atrialization of the RV
Ebstein’s anomaly association
Li during pregnancy
EKG in ALCAPA
q waves in 1, aVL, V5, V6, ST elevation in V5, V6
Down’s
AVCD (VSD most common)
Turner
coarctation
Noonan
pulmonary stenosis
Williams
supravalvar aortic stenosis
DiGeorge
TOF, interrupted aortic arch
Alagille
pulmonary artery stenosis
Endocarditis bugs
S. viridans, staph, HAECK
Endocarditis findings
Janeway lesions = palms/soles
Roth spots = retinal hemorrhage
Osler’s nodes = painful on fingers/toes
Endocarditis prophylaxis indications
Dental extraction, T&A, respiratory mucosal injury
Endocarditis prophylaxis treatment
1 hour prior to procedure - amox, clinda, cephalexin
ARF trigger
GAS pharyngitis (not other sources!)
ARF treatment
PCN (plus monthly prophylaxis), prednisone if severe carditis with CHF
ARF diagnosis
Jones criteria
KD age range
6 mo - 2 yr
Rate of coronary artery aneurysm in untreated KD
20%
Pericarditis EKG
global ST elevation, PR depression
Causes of pericarditis
Preceding URI (or uremia, ARF, TB)
Myocarditis EKG
low voltage
Causes of myocarditis
Virus (coxsackie, rhino, adeno)
Hypertrophic cardiomyopathy genetics
AD
Hypertrophic cardiomyopathy murmur increases with…
exercise, standing, Valsalva
Hypertrophic cardiomyopathy murmur decreases with…
squatting, handgrip
Most common causes of pediatric tachycardia
SVT (90%)
Types of SVT
AV nodal reentrant, AV re-entry, ectopic atrial, junctional, flutter
Most common pediatric bradycardia
3rd degree (complete
Causes of complete heart block
maternal SLE, L-TGA
Long QT syndrome genetics
AD
