Cardiology MCQ 349: Atrioesophageal fistula
Atrioesophageal fistula is a potential complication of:
a) AVNRT ablation
b) AVRT ablation
c) Pulmonary vein isolation
d) RVOT VT ablation
["Click here for the answer with explanation", "Correct Answer:"]
c) Pulmonary vein isolation
Atrioesophageal fistula is one of the dreaded complications of pulmonary vein isolation. It occurs due to thermal damage to the esophagus which lies adjacent to the left atrium. Thermal sensors in the esophagus are useful in preventing this complication.

Cardiology MCQ 353: Narrow P waves
Narrow P waves are seen in:
a) Sinus rhythm
b) Retrograde activation through lateral pathways
c) Retrograde activation through septal pathways
d) None of the above
["Click here for the answer with explanation", "Correct Answer:"]
c) Retrograde activation through septal pathways
P waves are narrower if the activation is from the centre of the heart as in AVNRT or septal accessory pathways because of simultaneous activation of both atria. Sinus P waves and P waves due to retrograde activation through lateral pathways have broader P waves as there is only sequential activation of atria.

Cardiology MCQ 353: ECG lead system for treadmill test
ECG lead system for treadmill test is known as:
a) Body surface mapping
b) Frank orthogonal leads
c) EASI 5 lead system
d) Mason-Likar torso leads
["Click here for the answer with explanation", "Correct Answer:"]
d) Mason-Likar torso leads
In Mason-Likar torso leads for treadmill, the limb leads are placed on the torso near the origin of the limbs. This produces changes in the QRS axis with a rightward shift and disappearance of Q waves in inferior leads. Hence it is not useful for diagnosis of QRS morphologies.

Cardiology MCQ 356: Right ventricular endomyocardial fibrosis
Region least involved in right ventricular endomyocardial fibrosis:
a) Right ventricular inflow
b) Right ventricular outflow
c) Right ventricular apex
d) Right ventricular body
["Click here for the answer with explanation", "Correct Answer:"]
b) Right ventricular outflow
Endomyocardial fibrosis is type of restrictive cardiomyopathy seen mostly in the tropics and sub tropics. There is progressive fibrosis and obliteration of the right ventricle, predominantly the inflow tract and the apex. The right ventricular outflow tract (RVOT) is relatively spared and is often dilated. This leads to the physical finding of RV out...
