Answer:
B) A ventricular origin of the condition
Explanation: Widening of the QRS complex is related to slower spread of ventricular depolarization. This occurs may be due to
- aberrant conduction,
- ventricular preexcitation and
- with a cardiac pacemaker.
- disease of the His-Purkinje network
- reliance on slower, muscle-to-muscle spread of depolarization.

TYPE A: Choose the ONE BEST answer in each case. Which statement about various cardiac arrhythmias is TRUE? O A typical ventricular rate during an episode of ventricular tachycardia is 1000 min-1 Sinus arrhythmia occurs when the ventricular rate rises to be higher than 100 min-1 In complete atrioventricular block, there is always a complete absence of QRS- complexes from the electrocardiogram.
