Vedclass · Answer

(A) The correct answer is $(A)$. By counting the number of $QRS$ complexes that occur in a given time period,one can determine the heart beat rate (pulse) of an individual. The $P$-wave represents the electrical excitation (depolarisation) of the atria,which leads to the contraction of both the atria. The $QRS$ complex represents the depolarisation of the ventricles,which initiates the ventricular contraction. The $T$-wave represents the return of the ventricles from an excited to a normal state (repolarisation). The end of the $T$-wave marks the end of systole.

List $I$	List $II$
$A$. $P$-wave	$I$. Beginning of systole
$B$. $Q$-wave	$II$. Repolarisation of ventricles
$C$. $QRS$ complex	$III$. Depolarisation of atria
$D$. $T$-wave	$IV$. Depolarisation of ventricles

List $I$	List $II$
$A$. $P$ wave	$I$. Heart muscles are electrically silent.
$B$. $QRS$ complex	$II$. Depolarisation of ventricles.
$C$. $T$ wave	$III$. Depolarisation of atria.
$D$. $T-P$ gap	$IV$. Repolarisation of ventricles.
