Rhythm InterpretationCâu 31 / 100

a.Ventricular bigeminy
b.Ventricular trigeminy
c.A couplet
d.Ventricular tachycardia
Giải thích
Bigeminy means every other beat is a premature ventricular contraction, alternating one normal beat and one PVC. Trigeminy is a PVC every third beat. A couplet is two PVCs in a row, and three or more consecutive PVCs at a rate above 100 constitute ventricular tachycardia.
