Read the following statements and select the correct ones (i) Nodal tissue is specialised cardiac musculature in human heart which has the ability to generate action potential due to an external stimuli (ii) Position of SAN - right corner of right atrium (iii) Position of AVN - right corner of ventricle (iv) AV bundle continues from AVN (v) Purkinje fibres are modified cardiac muscle fibres that originate from the atrioventricular node and spread into the two ventricles.

The cardiac pacemaker in a patient fails to function normally. The doctors find that an artificial pacemaker is to be grafted in him. It is likely that it will be grafted at the site of (a) atrioventricular bundle (b) purkinje system (c) sinu-atrial node (d) atrio-ventricular node
