Ans: C. Dual Chamber Pacemaker.
- This electrocardiogram demonstrates an artificial cardiac pacemaker which is responsible for initiating contractions within the atria as well as the ventricles.
- Note the double pacemaker spikes associated with each complete cycle of contraction.
- The first spike indicates stimuli to the atria, while the second pacemaker spike indicates initiation of ventricular contraction.
