Catheter induced ectopy is due to irritation of the local endocardium and will show all the features of a target ventricular ectopic for ablation,

Pacemapping at potential ablation sites is done at a rate slightly faster than the ventricular tachycardia. The QRS morphology should be a 12/12 match of the clinical tachycardia.

Isolated diastolic dysfunction as compared to isolated systolic dysfunction: a) Increased end diastolic volume b) Increased end systolic volume c) Increased ejection fraction d) None of the above

All of the following are seen in hyperkalemia except: a) PR prolongation b) Tall tented T waves c) Diminished P wave amplitude d) Narrow QRS complex

Which of the following is not true about abciximab? a) Glycoprotein IIb/IIIa blocker b) Orally active c) Monoclonal d) Used as an adjunct in PCI

Gross enlargement of cardiac shadow is unlikely in: a) Tetralogy of Fallot b) Pericardial effusion c) Posterior mediastinal tumour d) Ebstein’s anomaly

Coarctation of aorta is associated with all except: a) Endocardial fibroelastosis b) Mycotic aneurysm c) Aortic dissection d) Bicuspid aortic valve
