Which part of the heart serves as the natural pacemaker?

• Bundle of His

• SA node

• Purkinje fibers

• AV node

What is the primary reason for using temporary pacing in patients?

• To improve digestion

• To increase lung capacity

• To maintain adequate cardiac output and perfusion

• To enhance muscle growth

What is overdrive pacing used for?

• To improve kidney function

• To speed up a slow heart rate

• To slow down a fast heart rate
