what does each small box represent - .04 seconds
what does 1 large box (5 small boxes) represent - .20 seconds
what do 5 large boxes represent - 1 second
primary pacemaker - SA node w/expected firing rat of 60-100 bpm
backup pacemaker - AV node w/expected firing rate of 40-60 bpm
final pacemaker - ventricles w/expected firing rate less than 40 bpm
a normal PR interval is - .12-.20 seconds
a normal QRS interval is - < .12 seconds (.04-.11)
a normal QT interval is - .36-.44 seconds
the ST segment should be ____ with the _____ - level w/ the baseline
ST segment elevation and depression is an indication of - ischemia or injury to the heart
what does P wave represent on the ECG - atrial depolarization
what does P wave represent on the ECG - ventricular depolarization
, what does P wave represent on the ECG - repolarization of ventricles
rhythms that originate above the ventricles normally have a ___
QRS complex - narrow QRS complex
rhythms that originate in the ventricles normally have a ___ QRS complex - wide QRS complex
A Flutter - 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 - 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) - NO DROPPED QRS
PR interval > .20 secs
(2*AVB) - PR wave gets longer + longer UNTIL QRS is DROPPED
2*AVB type 2 - PR intervals remain constant, but some QRS is DROPPED
3*AVB - rate: 60 - 100 HR
PR intervals vary
R-R constant, P-P constant
