therefore not going through the normal AV node and its going through the
accessory pathway before it gets to the AV node i.e. there is pre-excitation. If it
was going through the AV node, you would have a normal PR interval and no
Delta wave

Q

RBBB after what surgery

A

TOF

157
Q

Narrow split S2 in

A

severe pulm HTN

158
Q

Fractional shortening:

A

Distance between walls of ventricle in systole and diastole.

159
Q

Norwood procedure

A

– separating right and left pulmonary arteries
from main pulmonary artery and connecting the main pulmonary
artery to the aorta (DSK procedure), then conduit from subclavian
artery or ventricle to pulmonary arteries (BT shunt or Sano shunt
respectively). Risk of shunt blockage in premature infants,
dehydration or fever and can get subsequent ischaemia. Often on
aspirin and diuretics to reduce pulmonary blood flow because of
increasing shunt as child grows. Saturations will be in the 70ǯs and the
shunt will give a continuous murmur.

160
Q

ebsteins anomaly:

A

downward displacement of abnormal tricuspid valve into
right ventricle. Leaflets often separated. Reduced right ventricular output due
to variable degrees of tricuspid regurgitation, poorly functioning small right
ventricle and right ventricular outflow tract obstruction by valve leaflet.
o Increased risk of WPW.

161
Q

Scimitar syndrome:

A

dextroposition associated with hypoplasia of a lung
and anomalous pulmonary venous return from that lung.

162
Q

Long QT which channel affected 1-10

A

LQTS 1, 2, 5, 6, 7: potassium channel.
LQTS 3, 4, 9, 10: sodium channel.
LQTS 8: calcium channel.

163
Q

Triggers for long QT 1-3

A

There are three common types
Type 1 and 2 respond well to betablocker treatment, because the triggers for type 1 (60%) is exercise; swimming is especially dangerous. For type 2 (30%) the commonest triggers are sudden and loud noise (especially at night), and emotional excitement. In type 3 (10%) events usually occur at night, and defibrillator pacemakers are most commonly needed in this group.

164
Q

Newborn with cyanosis and left axis deviation highly suggestive of

A

Tricuspid atresia (cf ebsteins with P waves changed, RBBB +- WPW right side affected)

165
Q

Pulmonary banding possible indications

A

AVSD
Swiss cheese multiple VSDs
vSD with CoA
Truncus

166
Q

Frederichs ataxia heart problem

A

Hypertrophic cardiomyopathy

167
Q

Continuous murmur at birth pink and blue causes

A

Coronary a fistula

Pulmonary atresia with VSD

168
Q

Asian child with SCN5A and typical ECG

A

Brugada (if fever needs admission) Na channel

169
Q

Upright t RVH age

A

8 days - 8 years

170
Q

2 days severe cyanosis and LAD

A

TA

171
Q

Why is there fixed splitting in ASD

A

The ASD creates a left to right shunt that increases the blood flow to the right side of the heart, thereby causing the pulmonary valve to close later than the aortic valve independent of inspiration/expiration

172
Q

ECG: Negative p axis on I and/or aVf indicates??

A

Situs inversus
Lead reversal
Ectopic atrial tachy

173
Q

Causes of “water hammer pulse” / collapsing pulse

A

Physiological
Fever
Pregnancy

Cardiac lesions
Aortic regurgitation
Patent ductus arteriosus
Systolic hypertension
Bradycardia
Aortopulmonary window
Aneurysm of sinus of Valsalva
Syndromes or high-output states
Anemia
Cor pulmonale
Cirrhosis of liver
Beriberi
Thyrotoxicosis
Arteriovenous fistula
