The document describes various types of tachyarrhythmias and bradyarrhythmias based on their rate, rhythm, QRS width, and other features. Tachyarrhythmias are categorized as narrow complex or wide complex, and further divided into regular or irregular rhythm. Narrow complex rhythms include sinus tachycardia, atrial flutter, supraventricular tachycardia, junctional rhythm, atrial fibrillation, atrial flutter with variable block, and multifocal atrial tachycardia. Wide complex rhythms include ventricular tachycardia, SVT with aberrancy, ventricular fibrillation, and torsades de pointes. Bradyarrhythmias include sinus bradycard

- 2. Tachyarrhythmia Narrow complex Regular ? SVT ? Sinus tachycardia ? Atrial flutter ? Junctional rhythm Irregular ? Atrial fibrillation ? Atrial flutter with variable block ? Multifocal atrial tachycardia Wide complex Regular ? Ventricular tachycardia ? SVT with aberancy Irregular ? Atrial fibrillation with preexcitation ? AF with aberrancy ? Ventricullar fibrillation ? Torsades de pointes
- 4. Sinus Rhythm
- 6. Atrial Flutter Rate A: 300 V:<150 Rhythm Regular QRS Narrow Feature sawtooth
- 7. Supraventricular Tachycardia Rate >150 Rhythm Regular QRS Narrow Feature P not visible
- 8. Junctional rhythm Rate 40-60 Rhythm Regular QRS Narrow Feature P not visible, inverted or after QRS
- 9. Atrial fibrillation Rate A: 600 V:variable Rhythm irregular QRS Narrow Feature Irregularly irregular
- 10. Atrial flutter with variable block Rate A: 300 V:<150 Rhythm Irregular QRS Narrow Feature sawtooth
- 11. Multifocal Atrial Tachycardia Rate Variable Rhythm Irregular QRS Narrow Feature 3 or more P waves that differ in polarity (up/down), shape, and size
- 12. Wide complex
- 13. Ventricular Tachycardia Rate >150 Rhythm Regular QRS wide Feature No visible p
- 15. Ventricular fibrillation Rate Very fast Rhythm Irregular QRS bizarre Feature no recognizable P, QRS, or T waves
- 16. Torsades de pointes Rate V: 150-200 Rhythm Irregular QRS QRS complexes display ¡°spindle-node¡± pattern Feature no recognizable P &T waves, prolong QT before occurence
- 17. Bradyarrhythmia
- 18. Bradyarrhythmia Sinus Bradycardia 1st degree Heart block 2nd degree Heart block (Mobitz 1) 2nd degree Heart block (Mobitz 2) 3rd degree Heart block
- 20. 1st degree Heart block ? P-R Interval > 200msec (5 small box) ? No dropped beat
- 21. 2nd degree heart block , Mobitz 1 (Wenckebach) ? Progressive prolongation of P-R intervals ? P-P intervals constant ? Dropped beat ? PR interval is longest immediately before the dropped beat ? PR interval is shortest immediately after the dropped beat
- 22. 2nd degree HB Mobitz II ? Intermittent non-conducted P waves without progressive prolongation of the PR interval ? PR interval in the conducted beats remains constant ? P-P constant ? RR interval surrounding the dropped beat(s) is an exact multiple of the preceding RR interval
- 23. 3rd degree HB (complete HB) ? complete absence of AV conduction (AV dissociation) ? Perfusing rhythm is maintained by a junctional or ventricular escape rhythm
- 24. Pulseless Electrical Activity (PEA) ? presence of coordinated electrical activity in myocardium but no detectable cardiac output ? formerly known as EMD (electromechanical dissociation)
- 25. Asystole
- 26. Arrest rhythm ? VF ? VT ? PEA ? Asystole
