Cardiology MCQ 362: Tachycardia with LBBB pattern and left axis
Tachycardia with LBBB pattern and left axis deviation:
a) Mahaim fibre tachycardia
b) Bundle branch reentrant tachycardia
c) ARVD
d) All of the above
["Click here for the answer with explanation", "Correct Answer:"]
d) All of the above
LBBB pattern with left axis deviation in wide QRS tachycardia should make us suspect Mahaim fibre tachycardia or bundle branch reentrant tachycardia. The sinus rhythm ECG will be normal in Mahaim fibre tachycardia while some bundle branch block pattern is likely in bundle branch reentry in sinus rhythm ECG. Another possibility which has to be thought about is ARVD. Careful inspection ...

Cardiology MCQ 369: Vein with lowest oxygen saturation
Which vein has the lowest oxygen saturation?
a) Coronary sinus
b) Saphenous vein
c) Renal vein
d) Femoral vein
["Click here for the answer with explanation", "Correct Answer:"]
a) Coronary sinus
Oxygen extraction is maximum in the coronary circulation so that coronary sinus has the lowest oxygen saturation.

Cardiology MCQ 368: Vein with highest oxygen saturation
Which vein has the highest oxygen saturation?
a) Coronary sinus
b) Saphenous vein
c) Renal vein
d) Femoral vein
["Click here for the answer with explanation", "Correct Answer:"]
c) Renal vein
Renal blood flow is much more than is needed for the metabolic demands of the kidney and hence the renal vein has the highest oxygen saturation.
