Cardiology MCQ 298: Non dippers on ambulatory BP
Non dippers on ambulatory BP monitoring are those whose nocturnal BP falls less than:
a) 10%
b) 15%
c) 20%
d) None of the above
["Click here for the answer with explanation", "Correct Answer:"]
a) 10%
It is possible to calculate the level of dip in pressures during sleep so as to classify individuals into dippers, extreme dippers, non dippers and reverse dippers. Dip = (1-Systolic BP during sleep/Systolic BP while awake), expressed as a percentage. Negative value indicates reverse dipper. Values less than 10 percent are considered in the non-dipper range, while 10-20% range constitutes the dippers and more than 20% c...

Cardiology MCQ 300: Epicardial ablation for VT
Epicardial ablation for VT is considered when:
a) When intracardiac approach has failed
b) Intracardiac thrombi present
c) Prosthetic valves precluding an intracardiac approach
d) All of the above
["Click here for the answer with explanation", "Correct Answer:"]
d) All of the above
Epicardial approach has a higher risk of complications and hence is often considered only after an endocardial approach fails. Sometimes it is the first line approach when the ECG pattern or the underlying heart disease like dilated cardiomyopathy makes the possibility of epicardial circuits high. An intracardiac thrombus or prosthetic mec...

a) Patent ductus arteriosus
b) Coarctation of aorta
c) Subaortic stenosis
d) Parachute mitral valve (congenital mitral stenosis)
["Click here for the answer with explanation", "Correct Answer:"]
a) Patent ductus arteriosus
In Shone complex, reduced distal flow due to one stenosis in the fetal period is thought to cause further distal stenoses. The sequence of these stenoses are from (d) to (b) above. There could be supramitral ring as well.
