A delayed conduction of the AV node is manifested by a:
a. prolonged PR interval
b. widened QRS
c. inverted P wave
d. absence of a P wave - ANSWERa. prolonged PR interval
Which of the following waveforms represent the electrical event that should
initiate ventricular contraction? - ANSWERQRS complex
What is the normal range of the PR interval? - ANSWER0.12-0.20
What is the normal length of the QRS interval? - ANSWERbelow 0.12
What bpm rate is Sinus Tachycardia on a strip? - ANSWER101-160 bpm
Which of the following describes a cells ability to spontaneously generate an
impulse? - ANSWERautomaticity
, Which node independently conducts a rate of 40-60 in an adult patient? -
ANSWERAV node
Which node independently conducts a rate of 60-100 in an adult patient? -
ANSWERSA node 'the pacemaker of the heart'
What does the T-wave represent? - ANSWERventricle repolarization
What is the normal PQRS ratio? - ANSWER1:1
What is the rate on a strip for sinus bradycardia? - ANSWERless than 60 bpm
How do you calculate the rate on a strip? - ANSWERmultiply the number of
QRS's by 10
*pay attention to marks on strip to count right*
How to differentiate between normal sinus rhythm and sinus arrhythmia -
ANSWERthe distance between each R (peak in QRS wave) is different and
NOT the same within a strip
the activation of BLANK system causes in a release in epinephrine which
results in an increase in heart rate, blood pressure, and cardiac output -
ANSWERsympathetic nervous system
