5 rights of delegation 1. Right Task

4. Right Directions / Communication
5. Right Supervision / Evaluation
properties of cardiac cells -Automaticity - Ability to initiate an impulse spontaneously and continuously
-Excitability - Ability to be electrically stimulated
-Conductivity - Ability to transmit an impulse along a membrane in an orderly
manner
-Contractility - Ability to respond mechanically to an impulse
SA node -pacemaker of the heart
-located in Rt atrium
-produces heart rate
-beats at 60-100 bpm
parasympathetic nervous system (vagal response)
-decreases rate of SA node
-decreases heart rate
-slows impulse conduction of AV node
, sympathetic nervous system (fight or flight)
-increases rate of SA node
-increases heart rate
-increases impulse conduction of AV node
-increases cardiac contractility
Electrocardiogram monitoring -Graphic tracing of electrical impulses produced by heart
-Waveforms of ECG represent activity of charged ions across membranes of
myocardial cells
depolarization contraction
repolarization Return of the cell to resting state
secondary pacemakers of the heart -AV Node: beats at 40-60 bpm
-His-Purkinje Fibers: 20-40 bpm
reading ECG -small / little boxes = 0.04 seconds
-bolded box lines = 0.2 seconds
isoelectric line The baseline of the ECG
PR interval (PRI) -from onset of P wave to onset of QRS
-Normal duration = 0.12-0.20 sec
-represents atria to ventricular conduction time
prolonged PR interval may indicate first degree heart block
QT interval -total ventricular activity
-0.34-0.43
-measured from beginning of QRS to the end of the T wave
-varies with heart rate
-less than half of the R to R interval
P wave caused by atrial depolarization
QRS complex -ventricular depolarization
-less than 0.12 seconds
-Q wave greater than 1/3 the height of the R wave, greater than 0.04 seconds are
abnormal and may represent an MI (if Q wave is wider or taller than a box it can
be a pathological Q)
