◉ properties of cardiac cells. Answer: -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. Answer: -pacemaker of the heart
-located in Rt atrium
-produces heart rate
-beats at *60-100 bpm*
◉ parasympathetic nervous system. Answer: (vagal response)
,-decreases rate of SA node
-*decreases heart rate*
-slows impulse conduction of AV node
◉ sympathetic nervous system. Answer: (fight or flight)
-increases rate of SA node
-*increases heart rate*
-increases impulse conduction of AV node
-increases cardiac contractility
◉ Electrocardiogram monitoring. Answer: -Graphic tracing of
electrical impulses produced by heart
-Waveforms of ECG represent activity of charged ions across
membranes of myocardial cells
◉ depolarization. Answer: contraction
◉ repolarization. Answer: Return of the cell to resting state
◉ secondary pacemakers of the heart. Answer: -AV Node: beats at
40-60 bpm
-His-Purkinje Fibers: 20-40 bpm
, ◉ reading ECG. Answer: -small / little boxes = 0.04 seconds
-bolded box lines = 0.2 seconds
◉ isoelectric line. Answer: The baseline of the ECG
◉ PR interval (PRI). Answer: -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. Answer: may indicate first degree heart
block
◉ QT interval. Answer: -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. Answer: caused by atrial depolarization
◉ QRS complex. Answer: -ventricular depolarization
