- 1Rhythms that arise from the ventricles have abnormalities in ______, that look _____,_____, and, ________.QRS complex; big, wide, and ugly
- 2multifocalpvc's that look different coming from more than one site
- 3unifocalpvc's that look the same
- 4PVCearly depolarization begins in the ventricle instead the sinus node
- 5Causes of PVCanxiety, caffeine, alcohol, tobacco, dig toxicity, antiarrhythmic meds, electrolyte imbalance
- 6Significant PVC'smore than 6 PVC's
multifocal
paired "couplet" PVC's
triple PVC's
R on T PVCs - 7bigeminypvc's are occurring in every other beat
- 8trigeminypvc's every 3 beats
- 9coupletpvc's that occur in pairs
- 10triplet3 pvc's in a row
- 11R on Tfalls on the down slope of the preceding T wave
- 12Why is R on T dangerous?correlates with ventricular repolarization, myocardium vulnerable state, cause repetitive ventricular contraction resulting in vtach and vfib
- 13vtach3 or more pvc's in a row at a rate greater than 100 bpm
- 14idioventricularthe impulse of conduction starts in the ventricles. SA and AV nodes have failed
- 15vfibabsence of an audible heartbeat, palpable pulse, and respiration
- 16What rhythm gets defibrillation as a tx?vfib and pulseless vtach
- 17Which rhythm gets cardioversion as a tx?vtach w/pulse
