- dangerous PVCs
•Bigeminy •Trigeminy •Multifocal •Short run of V-tach •Greater than 6/ minute
PVC Treatment Lidocaine, Amiodarone
Idioventricular rhythms SA node and AV junction fail- ventricles depolarize at their own rate (20-40bpm). Wide QRS
Idioventricular rhythms Prognosis lethal
Accelerated idioventricular rhythm rate greater than 40 but less than 100. Wide QRS. (Has the best correlation with reperfusion after MI intervention) 1 / 3
Idioventricular rhythm treatment amiodarone, pacing
What med should you not give to idioventricular rhythm?lidocaine
Ventricular tachycardia prognosis lethal
Pulseless V-tach CPR
V-tach w/ pulse cardioversion
Torsades de Pointes •QRS complexes appear to twist in a spiral pattern 2 / 3
•Causes hemodynamic instability Lethal
Torsades de Pointes Treatment
- Infusion of magnesium sulfate (treatment of choice)
- pacemaker
Ventricular Fibrillation 1.Defibrillate if shockable and do CPR- shock at least twice before epi 2.Next Epi is given (1 mg) every 3-5 minutes 3.Amiodarone 300 mg w/ first dose and 150 mg on second dose 4.If still pulseless, repeat cycle- start CPR and defibrillating again
Defib what rhythms Pulseless v-tach and v-fib
Defib Shock Voltages 1st- 200 joules 2nd- 300 joules 3rd- 360 joules
