List of top Medical Laboratory Technology Questions on Cardiology asked in CUET (PG)

The waves associated with the electrical activity of the various parts of the heart tissue during each cardiac cycle are represented by letters P, Q, R, S, T and U. Which of these wave represent ventricular repolarization ?

Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : The conduction in the Atrio-ventricular (AV) node is slow i.e. 0.05 m/sec, there is a delay of approx. 0.1 second before excitation spreads to the ventricles.
Reason (R) : AV node delay enables the atria to empty the blood present within them into the ventricles before these contract.
In the light of the above statements, choose the most appropriate answer from the options given below :

The correct order of systemic circulation in a heart :
A. Aorta
B. Aortic valve
C. Left ventricle
D. Superior and inferior venae cavae
E. Right atrium

In Rheumatic heart disease, which valve has highest probability of deformation?
