A member asked:
What does pac, activation mark mean on an ekg? i understand that pac means premature atrial contraction, but what is activation mark?
A doctor has provided 1 answer
Pac: I presume the activation mark is where the premature artrial electrical signal begins for the early beat. On a ekg, it would be the p wave where the PAC starts. Best of luck-
