Guided Notes
3 key concepts
- 1
Unlike skeletal muscle, cardiac cells are physically and electrically connected, allowing for precise coordination to pump blood.
- 2
Pacemaker cells in the heart generate their own electricity, triggering action potentials and controlling heart rhythm via the intrinsic cardiac conduction system.
- 3
A defibrillator sends electricity through the heart to trigger action potentials in all cells at once, allowing the SA node to reset the rhythm.
