b. widened QRS
c. inverted P wave
d. absence of a P wave
Answer: a. prolonged PR interval
>> Which of the following waveforms represent the electrical event that should
initiate ventricular contraction?
Answer: QRS complex
>> What is the normal range of the PR interval?
Answer: 0.12-0.20
>> What is the normal length of the QRS interval?
Answer: below 0.12
>> What bpm rate is Sinus Tachycardia on a strip?
Answer: 101-160 bpm
>> Which of the following describes a cells ability to spontaneously generate an
impulse?
Answer: automaticity
>> Which node independently conducts a rate of 40-60 in an adult patient?
, Answer: AV node
>> Which node independently conducts a rate of 60-100 in an adult patient?
Answer: SA node 'the pacemaker of the heart'
>> What does the T-wave represent?
Answer: ventricle repolarization
>> What is the normal PQRS ratio?
Answer: 1:1
