Comment to Bite-sized EKG #4: Lazy Wolf!

  • There are no PVCs. Those wide beats are "pre-excited" sinus beats. Since he does not have symptoms, there is no WPW (pre-excitation + symptoms).

    • My mistake!

      It's the first time that I see (intermittent pre-excitation) at first glance it looks like PVCs.

      • The fact there is a "P" before each of these "PVCs" should be the first clue. Next question, is that: why a sinus drive beat gets all of a sudden short "PR" interval and a wide QRS?
