Ventricular Rhythm

early depolarization begins in the ventricle instead of the sinus node
causes: abnormal levels of electrolytes (dec potassium/magnesium), use of diuretics, toxins, stimulants (coffee, nicotine, cocaine), infection
1. Occurs in normal, healthy individuals no tx necessary if asymptomatic. tx depends on cause
  1. SIGNIFICANT PVCs: more than 6 PVCs in a min, multifocal, paired couplet PVCs, R on T PVCs, PVCs that are in runs of 3
    1. Tx: antiarrhythmic meds bc of high risk of v tach and v fib
PVC
1. multifocal: looks different
  1. unifocal: looks the same
2. ventricular bigeminy: PVCs every other beat
  1. trigeminy: PVCs every 3 beats
    1. quadrigeminy: PVCs every 4 beats
3. couplet: PVCs that occur in pairs
Tests: electrocardiogram, cardiac cath, electrophysiology testing
