All About Cardiovascular System and Disorders

Dreaded arrhythmia in association with WPW syndrome (Wolff-Parkinson-White syndrome) is: 1. Orthodromic atrioventricular re-entrant tachycardia (Orthodromic AVRT) 2. Antidromic atrioventricular re-entrant tachycardia (Antidromic AVRT) 3. Atrial fibrillation 4.

Aortic root angiogram showing saphenous vein graft in left anterior oblique (LAO) view.

Left atrial myxoma – echocardiogram with video in parasternal long axis view with systolic and diastolic frames. Mitral regurgitation is also seen on color Doppler.

A prominent R wave in lead aVR (aVR sign in Brugada syndrome) has been suggested as marker for development of life threatening arrhythmic events.

Digoxin toxicity has become far less common as the use of digoxin, especially that of the loading dose has come down.

Diagnosis based on the echocardiogram: a) Ebstein’s anomaly of tricuspid valve b) Idiopathic dilatation of right atrium c) Endomyocardial fibrosis d) None of the above Correct Answer

ECG showing polyphasic or splintered QRS in Ebstein's anomaly of tricuspid valve.

ECG showing multifocal atrial tachycardia (MAT). Three or more different P wave morphologies at a rate above 100/min defines MAT.

ECG demonstrating SVT with RBBB.

RVOT ventricular tachycardia is an ablatable tachycardia.
