what does P wave represent on the ECG - Correct Answer: repolarization of ventricles
rhythms that originate above the ventricles normally have a ___
QRS complex - Correct Answer: narrow QRS complex
rhythms that originate in the ventricles normally have a ___ QRS complex - Correct Answer: wide QRS
complex
A Flutter - Correct Answer: rate: 250 - 350 bpm HR varies!!
regularity: regular or irregular
P waves: "think of a shark fin or waves"
PR: not applicable - you don't measure it
QRS: < .12 secs
A Fib - Correct Answer: rate: fast & unmeasurable
regularity: irregular
P wave: NON. wavy baseline btwn QRS instead
PR: not applicable - you don't measure it
QRS: <.12 secs
(1*AVB) - Correct Answer: NO DROPPED QRS
PR interval > .20 secs
(2*AVB) - Correct Answer: PR wave gets longer + longer UNTIL QRS is DROPPED
2*AVB type 2 - Correct Answer: PR intervals remain constant, but some QRS is DROPPED
3*AVB - Correct Answer: rate: 60 - 100 HR

PR intervals vary
R-R constant, P-P constant
some QRS complexes are DROPPED
normal sinus rhythm - Correct Answer: rate: 60 - 100 bpm
regularity: regular
PR: upright., matching, married to QRS
PR: 0.12 - .20, constant
QRS: < .12 secs
sinus bradycardia (SB) - Correct Answer: < 60 bpm
regularity: regular
PR: upright, matching, married to QRS
PR: 0.12 - .20, constant

PR: 0.12 - .20, constant
QRS: < .12 secs
sinus arrhythmia (SA) - Correct Answer: rate: varies with respiratory pattern. you would still log HR when
documenting
regularity: irregular. longest R-R cycle exceeds shortest by .16 or greater [ inconsistent & irregular ]
P waves: upright, matching, married to QRS
