1. Flow of blood RA, RV, PA, lungs, LA, LV, Ao, body, IVC/SVC, repeat
2. Electrical SA, internodal (bachmann), AV, Bundle branches, purkinje fibers,
conduc- tion
cardiomyocytes
3. Pacemaker cell a cell generates spontaneous depolarizations that control the firing of all the
cells in the network
4. intrinsic rate 60-100
of SA
5. intrinsic rate
of AV junction 40-60
6. intrinsic rate
of ventricles
20-40 bpm
7. action potential depolarization + repolarization
8. SA node • no stable resting membrane potential
action
potential • pacemaker potential - slow influx of sodium ions
• threshold
• depolarization - rapid influx of calcium and sodium
• repolarization - efflux of potassium ions
