during PSVT in WPW impulse is conducted antegradely over normal AV system and retrogradely through bypass tract

atrial flutter and AF are common

ventricular response during atrial flutter or fibrillation is unusually rapid and may cause VF

Quinidine or flecainide slow conduction and increase refractoriness primarily of the AV node

more commonly in men

Q 8. it is not possible to assign a specific morphology to which of the following arrhythmia

atrial flutter

ventricular flutter

torsades de pointes

WPW syndrome with AF

monomorphic VT

polymorphic VT

slow VT

none of the above

Q 11. which of the following statements about VPCs is false

ventricular impulses are never conducted retrogradely to atrium

VPC that does not produce retrograde concealed conduction and fails to influence oncoming sinus impulse is termed interpolated VPC

antiarrhythmic agents can produce lethal arrhythmias

prophylactic antiarrhythmic therapy is recommended only for young patients with complicated MI.

intravenous beta blocker

intravenous calcium channel blocker

intravenous nitroglycerine

intravenous digoxin

Q 13. Infiltrative / inflammatory and neuromuscular disorders associated with increased ventricular arrhythmia risk include

sarcoidosis

myotonic muscular dystrophy

kearn- sayre syndrome

all of the above

Q 14. VT that shows an alternation in QRS axis is called

monomorphic VT

polymorphic VT

bidirectional tachycardia

torsades de pointes

Q 15. WPW syndrome is observed in patients with HCM associated with which mutation

ACTN2

S135L mutation

PRKAG2 mutation

CRYAB

Q 16. characterstics ECG findings that suggest VT are all except

QRS complex >.20 seconds

AV dissociation

inferior QRS frontal plane axis

concordance of QRS pattern in all precordial leads

Q 17. sustained VT is defined as VT that persists for

> 10 seconds

> 15 seconds

> 20 seconds

> 30 seconds

Q 18. verapamil is least effective / contraindicated in which of the following

idiopathic LV septal VT

accessory pathway mediated tachycardia

iv lidocaine

iv procainamide

iv amiodarone

iv beta blocker

Q 21. which of the following about AIVR is false

heart rate ranges from 60 to 120 bpm

occurs in acute MI

usually transient

treatment consists of β blockers

Q 22. QRS duration of a VPCs is

>110 ms

>120 ms

>130 ms

>140 ms

Q 23. which of the following is not a feature of WPW syndrome

short PR interval ( <0.12 seconds)

slurred upstroke of QRS complex (delta wave)

wide QRS complex

prolonged QT interval

Q 24. which of the following about is not true for sustained VT

almost always symptomatic

mostly associated with marked hemodynamic compromise

almost always leads to development of myocardial ischemia

all of the above

Q 25. repeated VT episodes requiring defibrillation is called

VT storm

VT paroxysm

VT battle

VT flow

incomplete RBBB

incomplete LBBB

complete RBBB

complete LBBB
