ARS: Arrhythmias Flashcards
Impulses take chaotic, random pathways in atria
Atrial Fibrillation
Sinus Tachycardia Description (HR, P wave, Sinus Massage Response)
100-180, Normal, Atrial rate may slow
Reentrant SVTs (HR, P wave, Sinus Massage Response)
140-250, Hidden or Retrograde, May abruptly terminate
Focal Atrial Tachycardia (HR, P wave, Sinus Massage Response)
130-250, Differs from normal P, AV block may increase (doesn’t usually revert)
Atrial Flutter (HR, P wave, Sinus Massage Response)
180-350, “Saw-toothed”, AV block may increase
Ventricular Tachycardia Description
Large, Wide QRS Complexes with normal rhythm (rate > 100 bpm)
Third Degree AV Block
P waves do not correlate to QRS complexes. (Atrial > Ventricular Rate)
1) P Waves present and followed by QRS
2) QRS is narrow and mostly regular but one P wave and QRS are early
3) The early P wave looks different than the others
Diagnosis?
Premature Atrial Contraction
No visible p waves with narrow regular QRS
Junctional Tachycardia
P waves preceding a narrow QRS in a very rapid, regular rhythm
Atrial Tachycardia
No P waves
Narrow QRS that is irregularly, irregular
Atrial Fibrillation
