30

ECG with superior QRS axis, LAD

AV Canal

31

Only cyanotic lesion in neonate with LAD/LVH

Tricuspid atresia

32

Tx of sick infant with SVT

D/C cardioversion 0.5-1 J/kg

33

Drug of choice for SVT

IV Adenosine

34

Delta wave on EKG

Wolff Parkinson White

35

Sawtooth pattern on EKG

Atrial flutter. Rate greater than 250 is common in children

36

Fibrillatory baseline and irregular heart rate

Atrial fibrillation

37

Dilatation and stretch of atrium

Think atrial flutter

38

Tx of atrial flutter

D/C cardioversion or slow AV node conduction with digoxin, beta blocker, or calcium channel blocker. Consider Coumadin if gone on for more than 24 hrs because of static blood flow and risk of dislodging clot

39

Wide QRS tachycardia

Ventricular tachycardia

40

Drug of choice for ventricular arrhythmias

Amiodarone

41

Drop attacks

Torsades de Pointes

42

Normal QT interval

Less than 0.45 sec

43

AR, long QT, deafness

Jervell Lange Nielsen

44

AD, long QT, no deafness

Romano Ward

45

Tx for long QT

Tx to prevent torsades: Beta blocker, pacing, or automatic internal cardiac defibrillator

46

Tx of torsades

Magnesium sulfate, pacing, then shock

47

Prolonged PR interval >200 msec

First degree heart block

48

Changing PR intervals with some P waves are not conducted (dropped QRS)

Second degree heart block. Mobitz type 1. Wenckebach

49

Equal PR intervals, some p waves are not conducted

2nd degree heart block, Mobitz type 2

50

No apparent relationship between p waves and QRS

Third degree heart block

51

Anti Ro and Anti La antibodies

Lupus. Causes congenital heart block from trans placental passage of maternal antibodies (IgG) directed against fetal conduction tissue

52

Tx for heart block

Pacemaker

53

Heart defect seen in trisomy 21

AV canal, VSD

54

Heart defect seen in XO

Coarctation of aorta

55

Heart defect seen in trisomy 13 and 18

VSD

56

Heart defect seen in 5p-

VSD

57

Heart defect seen in 22q11-

Truncus arteriosus, interrupted aortic arch, pulmonary atresia with VSD, tetralogy of Fallot.

Order FISH test for eval.

58

Heart defect seen in Noonan

Pulmonic stenosis, hypertrophic cardiomyopathy

59

Heart defect seen in Marfans

Aortic root dilatation/dissection
