What decreases the rate of heart beat and the speed of conduction of action potential?

What decreases the rate of heart beat and the speed of conduction of action potential?
  1. Adrenal medullary hormones
  2. Nodal tissue
  3. Autonomic nervous system
  4. Parasympathetic neural signals

Solution

Parasympathetic neural signals (another component of ANS) decrease the rate of heart beat, speed of conduction of action potential and thereby the cardiac output.
