Explanation / Answer

96. The following is located within the walls of the ventricles -

ans. e) Purkinje fibres ( The Purkinje fibres are present in the inner ventricular walls of the heart.)

97. the P wave represents the following on the electrocardiogram -

ans. a) Atrial Depolarization (In a normal EKG, a P wave represents atrial depolarization which resembles a small bump on the upper side of the baseline)

98. The QRS represents the following on the EKG -

ans. c) Ventricular Depolarization (In a normal EKG, a combination of 3 graphical deflections located centrally is called QRS wave.)

99. The following is hidden behind the QRS complex on the EKG -

ans. b) Atrial Repolarization

100. T wave represents the following on the EKG -

ans. d) Ventricular Repolarization
