The two escape pacemakers in the heart are the atrioventricular (AV) node and the Purkinje fibers. The AV node typically has an intrinsic rate of 40 to 60 beats per minute, while the Purkinje fibers have a lower intrinsic rate of about 20 to 40 beats per minute. These pacemakers take over when the primary pacemaker, the sinoatrial (SA) node, fails to generate impulses effectively.

How many pacemakers can a person have?
A person can only have one pacemaker. A pacemaker helps if you have problems with the beating of your heart. If you have two pacemakers the beating of your heart won't be normal.

What are the two types of motivation theories?
The two types of motivation theories are intrinsic motivation and extrinsic motivation. Intrinsic motivation comes from within oneself, driven by personal enjoyment or satisfaction. Extrinsic motivation, on the other hand, arises from external factors like rewards or consequences.
Intrinsic and extrinsic motivation?
Intrinsic is the term explaining phenomenon due to internal qunatities. Extrinsic is the term explaining the same phenomenon due to foreign materials added ie external materials. In case of pure Si or Ge, intrinsic conductivity becomes possible as temperature increases. As we add trivalent or pentavalent impurities along with Si or Ge, then we get extrinsic conductivity.
