Generates an electrical impulse spontaneously and repetitively - answer automaticity
Responds to electrical impulse and depolarizes - answer Excitability
Sends electrical impulse from cell membrane to cell membrane - answer Conductivity
Muscle cells shorten their fiber length in response to electrical stimulus - answer
Contractility
order of conduction through the heart – answer SA AV bundle of his bundle branch
purkinje fiber
the slower the beat, the [better/worse] the block - answer worse
most blocks are [tachy/brady ]cardic - answer Brady
The SA node is what part of the heart beat? - answerP wave
the AV node is what part of the heart beat? - answerPR interval
atrial depolarization is what part of the heart beat? - answerP wave
QRS complex is what part of the heart beat? - answerventricular depolarization

ECG paper
one small box ____ sec
one large box ____ sec - answer0.04
0.20
how many large boxes in 6 seconds - answer30
more than __ boxes between R waves is brady
less than __ boxes between R waves is tachy - answer5
3
if the beat is irregular monitor it for how many minutes? - answer1
normal PR interval - answer.12 .20
, normal QRS complex - answer.04 .12
[atrial/ventricular] arrhythmias are more lethal - answerventricular (these affect cardiac
output)
number one distinguishing characteristic between a stable and unstable patient -
answerconfusion
PAC and SVT are [atrial/ventricular] dysrhyythmias - answeratrial
PAC - answerpremature atrial contraction
SVT - answersupraventricular tachycardia
two electrolytes you may worry about in the heart - answerK Mg
alcoholic and bulimics have abnormally low __ - answerMg
Ectopic focus of atrial tissue fires an impulse before next sinus impulse is due -
answerPAC
self-limiting arrhythmia, remove the trigger to cure - answerPAC
Rapid stimulation of atrial tissue occurs at a rate of >150 to 280 beat/min with a mean of
170 beats/min in adults. - answerSVT
rate of SVT - answer150 280
treatment for SVT - answervagal (first intervention if it does not resolve spontaneously)
a for a
anti-arrhythmic drug - answeramiodarone
treatment of choice for recurrent SVT - answerradiofrequency ablation
drug to administer if vagal doesn't work for SVT - answeradenosine (cardizem,
amiodarone)
when this drug is administered the patient is being treated for SVT (stops patient's
heart) - answeradenosine
what class is cardizem - answercalcium channel blocker
