Question 1

PVC

Premature Ventricular Contraction

Answer 1

• A premature ventricular beat that originates suddenly.
• Produces a giant ventricular complex on EKG.
• PVC’s occur early in the cycle.
• The most likely reason for a ventricular automaticity focus to become irritable is hypoxia.
• When you see a PVS, remember that this represents a premature ventricular contraction. (A premature pulse beat will be weak but present)
