Basic Arrythmias Basic Arrythmias Presentation Transcript

  • BASIC ARRHYTHMIAS By G. Abano
  • After 1 1/2 hour of discussion, students will be able to familiarize with common cardiac arrhythmias Specifically, we will be able to distinguish; OBJECTIVES 2. Sinus Rhythm 3. Premature Atrial Contractions 4. Atrial Flutter 5. Atrial Fibrillation 6. Ventricular Tachycardia 7. Ventricular Fibrillation
  • The heart
  • Conduction S ystem SA NODE COMMON BUNDLE BUNDLE AV NODE BRANCHES PURKINJE FIBERS
  • Waveforms
  • Sample Rhythm Normal S inus Rhythm
  • Sample Rhythm Sinus Bradycardia
  • Ventricular rate/rhythm 58 bpm/regular This rhythm strip is from a 54- year-old man who had a syncopal episode. Atrial rate/rhythm 58 bpm/regular PR interval 0.20 sec QRS duration 0.08 sec Identification Sinus bradycardia
  • Sample Rhythm Sinus Tachycardia
  • Ventricular rate/rhythm 130 bpm/regular Atrial rate/rhythm 130 bpm/regular PR interval 0.14 to 0.16 sec QRS duration 0.06 to 0.08 sec Identification Sinus tachycardia
  • Premature Atrial Ventricular rate/rhythm 93 bpm/regular Contractions Atrial rate/rhythm 93 bpm/regular PR interval 0.16 sec QRS duration 0.04 sec Identification Sinus rhythm with PAC
  • Sample Rhythm Atrial Flutter
  • Ventricular rate/rhythm 88 bpm/regular Atrial rate/rhythm Unable to determine PR interval Unable to determine QRS duration 0.06 sec Identification Atrial flutter with ST- segment depression
  • Sample Rhythm Atrial Fibrillation
  • Ventricular rate/rhythm 88 to 167 bpm/irregular Atrial rate/rhythmUnable to determine PR interval Unable to determine QRS duration 0.06 to 0.08 sec Identification Atrial fibrillation
  • Sample Rhythm Ventricular Tachycardia
  • Ventricular 176 bpm/regular rate/rhythm Atrial rate/rhythm None PR interval None • These rhythm strips are from a 44-year-old QRS duration 0.12 to 0.14 sec woman complaining of chest pain Identification Monomorphic ventricular tachycardia
  • Sample Rhythm Ventricular Fibrillation
  • Ventricular rate/rhythm Unable to determine Atrial rate/rhythm None PR interval None QRS duration None Identification Coarse ventricular fibrillation
  • We Practice Ventricular 91 bpm/Regular except for the event rate/rhythm Atrial rate/rhythm 91 bpm/Regular except for the event PR interval 0.16 sec QRS duration 0.06 sec Identification Sinus rhythm with a nonconducted PAC
  • Ventricular rate/rhythm 107 bpm (sinus beats)/ Regular except for the events Atrial rate/rhythm 107 bpm (sinus beats)/ Regular except for the events PR interval 0.20 sec (sinus beats) QRS duration 0.08 sec (sinus beats) Identification Sinus tachycardia with uniform PVCs
  • Identify the Rhythm
  • Identify the Rhythm
  • All that is worth cherishing begins in the heart, not the head. Suzanne Chapin
