Q 11. 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 12. 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.

Q 13. QRS duration of a VPCs is

>110 ms

>120 ms

>130 ms

>140 ms

Q 14. which of the following about idiopathic outflow tract VT is false

produces monophasic R waves in leads II , III & aVF

typically occurs as nonsustained bursts of VT

cycle length oscillations are common

more commonly in men

Q 15. repeated VT episodes requiring defibrillation is called

VT storm

VT paroxysm

VT battle

VT flow

Q 16. which of the following is unique in its suppression with verapamil

idiopathic LV septal VT

VT associated with LV dilated cardiomyopathy

Bundle branch reentrant VT

all of the above

Q 17. most uniform sustained VT associated with LV dilated cardiomyopathy can be mapped to

mitral valvular region

tricuspid valvular region

pulmonary valvular region

all of the above

Q 18. 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 19. sustained VT is defined as VT that persists for

> 10 seconds

> 15 seconds

> 20 seconds

> 30 seconds

Q 20. 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 21. which of the following statements about VPCs is false

may occur in up to 80% of patients with previous MI

on ECG show wide (usually >.12 seconds) bizarre QRS complexes not preceded by P wave

when they arise in specialized conduction system ( fascicles) , they may be <.12 seconds in duration

they result in a fully compensatory phase

Q 22. Infiltrative / inflammatory and neuromuscular disorders associated with increased ventricular arrhythmia risk include

sarcoidosis

myotonic muscular dystrophy

kearn- sayre syndrome

all of the above

Q 23. which of the following is not true regarding WPW syndrome

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

Q 24. AIVR has overlap features with

monomorphic VT

polymorphic VT

slow VT

none of the above

Q 25. 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

when fixed coupling is not present and interval between VPCs has a common denominator, ventricular parasystole is said to be present

trigeminy means two sinus beats followed by a VPCs

two successive VPCs are termed pairs or couplets

≥ 3 consecutive VPCs are termed VT when the rate exceeds 160 bpm
