depolarization - inside of cell becomes positive, outside negative
- contraction
- na+ channel opens
- ELECTRICAL
repolarization movement of cells = inside is negative again
- na+ channels close, k+ channels open
- MECHANICAL
p wave - (p) atrial depolarization
qrs wave - (qrs) ventricular depolarization
t wave - (t) ventricular repolarization

refractory period per of time where cardiac cells cannot respond to
stimulus
absolute refractory period beginning of qrs to peak of t wave
relative refractory (vulnerable per of - cardiac cells have repolarized enough to respond to
repolarization) strong stimulus
- during this per a strong stimulus may overtake the
pacemaker of the heart
- ex. PVC during vulnerable period may turn into
vtach or torsades
- prolonged QT interval inc possibility
causes of prolonged qt intervals haldol, bradycardia, hypokalemia
automaticity ability of pacemaker cells to initiate electrical impulse
excitability ability of muscle cells to respond to outside stimulus
conductivity ability to recieve electrical stimulus and conduct
impulse to adjacent cells
contraction cardiac cells shorten = muscular contraction in
response to electrical stimulus
