ECG tracings Flashcards
FA 277-279. Tracings only; still review additional info. Done.
Shifting sinusoidal waveforms
Torsades de pointes (polymorphic V-tach)
Delta wave w/ shortened PR intervals
WPW synd
Irregularly irregular. No discrete P waves btwn irregularly spaced QRS complexes
A-fib
Rapid back-to-back depolarization waves; sawtooth appearance
A-flutter
Completely erratic rhythm w/ no identifiable waves
V-fib
Asymptomatic prolongation of PR interval (>200 ms)
1st degree AV block
Progressive lengthening of the PR interval until there’s finally a P wave not followed by a QRS complex
2nd degree AV block type 1
P waves not followed by a QRS complex. This is not preceded by a progressive lengthening of PR interval
2nd degree AV block type 2
P waves bear no relation to QRS complexes
3rd degree (complete) AV block
