All About Cardiovascular System and Disorders

Estimation of right ventricular systolic pressure by Doppler echo is from: a) Velocity of tricuspid regurgitation jet b) Velocity of pulmonary regurgitation jet c) Area of tricuspid regurgitation

Measures useful in preventing interaction between implanted pacemaker and electrocautery: a) Using bipolar cautery b) Placing the indifferent plate electrode in such a way that the current path

Function of magnetic reed switch in an ICD (implantable cardioverter-defibrillator): a) Changes pacing mode to asynchronous (e.g. VVI to VOO) b) Suspends all tachyarrhythmia therapies c) None of

Colour flow jet area in severe mitral regurgitation: a) Less than 20% of left atrial size b) More than 40% of left atrial size c) More than 20%

Effective regurgitant orifice in severe mitral regurgitation is: a) 0.2 sq cm or more b) 0.3 sq cm or more c) 0.4 sq cm or more d) None

Carpentier type in mitral valve prolapse - Cardiology MCQ

Enhanced tendency for arrhythmias in pregnancy In general there is an enhancement of tendency for arrhythmias in pregnancy. Isolated ventricular ectopic beats are probably the commonest arrhythmia in

Right ventricular apical pacing and mitral regurgitation Right ventricular apical pacing may sometimes cause mitral regurgitation or worsen a pre-existing mitral regurgitation. Several mechanisms have been considered for

Electrosurgery and pacemakers Electrosurgical equipment use radiofrequency energy in the range of 0.1 to 5 MHz. This can cause electromagnetic interference (EMI) with pacemakers and other cardiac implantable

MRI conditional pacemakers Conventionally MRI (magnetic resonance imaging) is contraindicated in those with implanted pacemakers due to possibility of electromagnetic interference (EMI) with pacemaker function. MRI-conditional means that
