Atrial septal defect (ASD) with bidirectional shunt Atrial septal defect (ASD) with bidirectional shunt: Subcostal four chamber view shows a large defect in the interatrial septum (ASD). Right

Severe tricuspid regurgitation – echocardiogram Echocardiogram in apical four chamber view shows severe tricuspid regurgitation as a large mosaic jet filling more than half of a dilated right

Maximum dose of tPA (Alteplase) for thrombolysis in acute myocardial infarction:   a) 30 mg b) 50 mg c) 70 mg d) 100 mg Correct answer: d) 100

Monomorphic ventricular premature complex (VPC) Basic rhythm in the ECG is sinus rhythm at around 60/min. There are two wide QRS complexes seen in lead II rhythm strip.

Old inferior wall infarction and lateral ST depression ECG shows sinus rhythm at around 75/min, with pathological Q waves in inferior leads, indicating old inferior wall myocardial infarction.

Popliteal angiogram Popliteal angiogram is usually obtained as part of the femoral angiogram by panning the table downwards to cover the popliteal artery as the contrast flows down

Evolved anterior wall myocardial infarction ECG shows sinus rhythm at a rate of around 100/min, with QS complexes in anterior leads along with a coved ST segment elevation

Very wide QRS complex Width of the QRS complex in this ECG is about 200 ms. It is so wide that there is hardly any ST segment visible.

Pacing in complete heart block – ECG Pacing in complete heart block (CHB): Initial part of the ECG shows narrow QRS complexes at a rate of around 43/minute.

AV block with escape beats Basic PR interval is prolonged to about 320 ms. Some P waves marked as “?” in the lead II rhythm strip are fairly
