Name the three pacemakers of the heart and their rate: - ANS SA node (60-100bpm)
AV node (40-60bmp)
Bundle branches (20-40bpm)
Absolute refractory period - ANS Cardiac cells will not respond to further stimulation
Myocardial cells will not contract
Relative refractory period - ANS Vulnerable period (T-wave)
Cardiac cells can be stimulated to contract
Peaked p wave - ANS
Notched p wave - ANS
Inverted p wave - ANS
ST depression - ANS MI ischemia
