Rhythms Flashcards
PJC Traits
Inverted/missing P waves, early beat
PJC Treatment
Treat patient: badicardic algorithm if necessary
Junctional Escape Beat Traits
Happens late, missing P waves
treat bradicardic pt if necessary
Accelerated Junctions Rhythm
Might have inverted P waves, 60-100 bpm
Junctional Tachycardia
> 100 bpm
Ventricular beat features (IVR)
QRS and ST are deflections
Wide,weird QRS
20-40 bpm
Tx: transcutaneous pacing
Accelerated IVR
40-100bpm
No p waves
Monomorphic ventricular tachycardia
Uniform standing waves > 100 bpm
Polymorphic ventricular tachycardia
Non-uniform ventricular complexes
> 100 bpm
Vtach Tx no pulse
Treat like Vfib: defib
Stable Monomorphic Vtach Tx w/pulse
Amiodarone
Lidocaine
Unstable Monomorphic Vtach Tx w/ pulse
Cardiovert @100J
Stable Torsades Tx w/pulse
Magnesium Sulfate
Epi
Unstable Torsades Tx w/pulse
Defib
Stable Polymorphic Vtach Tx w/pulse
Amiodarone
Lidocaine
Unstable polymorphic Vtach Tx w/ pulse
Defib
______ interval for type of block
______ width for location of block
PR interval
QRS Complex: wider = lower in the heart
First Degree Heart Block Traits
PR interval longer than 0.20 sec, but constant
2nd Degree Wenkeback Heart block Traits
PR interval gets long and longer until it drops a QRS complex
2nd degree Mobitz 2 Heart Block Traits
Some P waves don’t get through AV node (missing QRS complexes)
PR interval constant when present
PP interval constant
3rd Degree Heart Block Traits
PP interval constant
RR interval constant
P waves & QRS complexes don’t match up
Cardioversion vs Transcutaneous Pacing
Cardioversion fixes fast rhythms
Transcutaneous Pacing fixes slow rhythms
First degree block Tx
Atropine if in AV node (narrow QRS)
Trans pacing if wide QRS
Heart Block Tx
Atropine if in AV node (narrow QRS)
Trans pacing if wide QRS
