Tachyarrhythmia Narrow complex Regular • SVT • Sinustachycardia • 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

- 6. Atrial Flutter Rate A:300 V:<150 Rhythm Regular QRS Narrow Feature sawtooth
- 7. Supraventricular Tachycardia Rate >150 RhythmRegular QRS Narrow Feature P not visible
- 8. Junctional rhythm Rate 40-60 RhythmRegular 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 withvariable block Rate A: 300 V:<150 Rhythm Irregular QRS Narrow Feature sawtooth
- 11. Multifocal Atrial Tachycardia RateVariable Rhythm Irregular QRS Narrow Feature 3 or more P waves that differ in polarity (up/down), shape, and size
- 12.
- 13. Ventricular Tachycardia Rate >150 RhythmIrregular QRS wide Feature No visible p
- 14.
- 15. Ventricular fibrillation Rate Veryfast Rhythm Irregular QRS bizarre Feature no recognizable P, QRS, or T waves
- 16. Torsades de pointes RateV: 150-200 Rhythm Irregular QRS QRS complexes display “spindle-node” pattern Feature no recognizable P &T waves, prolong QT before occurence

- 18. Bradyarrhythmia Sinus Bradycardia 1st degree Heart block 2nddegree Heart block (Mobitz 1) 2nd degree Heart block (Mobitz 2) 3rd degree Heart block
- 19.
- 20. 1st degree Heartblock • P-R Interval > 200msec (5 small box) • No dropped beat
- 21. 2nd degree heartblock , 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 HBMobitz 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)

- 26. Arrest rhythm • VF •VT • PEA • Asystole
