Question
Restrictive cardiomyopathy may be differentiated from the condition represented in JVP waveform as shown in the Photograph below by the following features ?
A. Diastolic pressures are equalized.
B. Pericardial effusion.
C. Thick pericardium is present.
D. a and c both.

Correct Answer » D Explanation |
 |
The condition represented in JVP waveform as shown in the photograph above represents constrictive pericarditis as it shows sharp y-descent.
Diastolic pressure are equalized in constrictive pericarditis but not in Restrictive cardiomyopathy Thickenned pericardium is seen in constrictive pericarditis but not in Restrictive cardiomyopathy
Right ventricular size is usually normal in both and pericardial effusion is usually absent in both, RV size and pericardial effusion, therefore can not distinguish between constrictive pericarditis and Restrictive cardiomyopathy
