EKGs can tell about electrical function in what ways -
Answer Rhythm, disturbances, and conduction disturbances
EKG's reflect..? -
Answer Electrical activity, not mechanical. To evaluate mechanical function, assess blood
pressure and peripheral pulses.
EKGs cannot tell about mechanical function, regarding -
Answer Structural disorders and perfusion disorders
Polarization, depolarization and repolarization are which states states -
Answer The ready state, the discharge state, and the recovery state
What are the inherent rates for the sinus node? -
Answer 60-100 beats/min
