The middle of phase 3 to beginning of phase 4 in the cardiac cycle where cardiac
cells are partially refractory and partially repolarized and certain cells can be
depolarized in response to electrical stimulus.
Relative Refractory Period
(Partial flush of the toilet)
Treatment for Beta Blocker Overdose
Glucagon: 1-5mg IV/IO (1st Line Drug)

and cells become ischemic?
Angina Pectoris
Chest pain that occurs at rest and is caused by coronary artery vasospasm? Risk
for Dysrhythmia, MI, Heart Block and Death
Prinzmetal Angina (PA)
Which electrolyte flows into cardiac cells to initiate depolarization?
Sodium (Na+)
Which electrolyte flows out of cardiac cells to to initiate repolarization?
Potassium (K+)

maintain depolarization and myocardial contractility?
Calcium (Ca++)
Which electrolyte stabilizes cell membrane and acts in concert with K+ and
opposes actions of Ca++?

Hypokalemia results in?
increased myocardial irritability
Hyperkalemia results in?
decreased automaticity/conduction
Hypocalcemia results in?
decreased contractility and increased irritability
Hypercalcemia results in?
Increased contractility
Hypomagnesemia results in?
decreased conduction
Hypermagnesemia results in?
increased myocardial irritability
Four properties of the Cardiac Conduction System
Excitability - cells respond to electrical impulse
Conductivity - cells pass impulse to one another
Automaticity - hearts ability to generate its own electrical impulse
Contractility - hearts ability to contract when stimulated
, Affects of RCA occlusion in terms of the SA node ischemia?
SA node becomes ischemic = slower firing rate (<60-100) or cease fire completely
causing another automaticity foci to take over such as AV (40-60) or Purkinje (20-40).
