Transcript

  • 1. Atrial & Ventricular Dysrhythmia Ahmad Thanin
  • 2. Objective Define the characteristics of atrial and ventricular arrhythmia. Relate the ECG features to the relevant physiological processes Develop reasoning skill that will enable you to explain some of the less commonly observed ECG abnormalities Identify potential pathways of care for the person presenting with a variety of ECG changes.
  • 3. QRS Complex Normal QRS: less than 3 small boxes ( less than 0.12 seconds), Narrow QRS. Abnormal QRS: more than 3 small boxes (more than 0.12 seconds), Wide QRS.
  • 4. Normal Sinus Rhythm
  • 5. Atrial Dysrhythmia Sinus Tachycardia. Sinus Bradycardia. Junctional Rhythm. SVT. Atrial Flutter. Atrial Fibrillation
  • 6. Sinus Tachycardia
  • 7. Sinus Bradycardia
  • 8. Junctional Rhythm Characteristics: Narrow QRS always. Absent of P wave, or Inverted P Wave, or Present P Wave but PR Interval less than 3 small boxes (less than 0.12 Seconds. Inverted P Wave comes after QRS.
  • 9. Junctional Rhythm – Cont. Absent Inverted PR Interval less than 0.12 seconds Inverted after QRS
  • 10. Types of Junctional Rhythms Junctional •Heart Rate 40 – 60 Beat per minute. Accelerated Junctional •Heart Rate 60 – 100 Beat per minute Junctional Tachycardia •Heart Rate above 100 Beat per minute
  • 11. Supra Ventricular Tachycardia – SVT
  • 12. Atrial Flutter – SAW Teeth
  • 13. Atrial Fibrillation
  • 14. Ventricular Dysrhythmia Idioventricular Rhythms Ventricular Tachycardia. Ventricular fibrillation. Torsade's DE points
  • 15. Idioventricular Rhythms Characteristics: Wide QRS always. Absent of P wave always. Heart Rate 20 – 40 BPM
  • 16. Ventricular Tachycardia Always check pulse with this Rhythm
  • 17. Ventricular Fibrillation Don’t Delay SHOCK Don’t waste the time for checking Pulse. Pulse always absent
  • 18. Torsade's DE points
  • 19. Time for Questions and Discussion
  • 20. Thank You
