      Acknowledgment — My appreciation to the following individual:
      • Dr. Jenda Stros (Liberec, Czech Republic) — for providing me with the case for ECG Video-Blog #9.
      --------------------------------
      --------------------------------
      The patient is a 75-year old woman who presented to the Emergency Department with syncope and shortness of breath. A diagnosis of Complete (3rd-Degree) AV Block was made from the ECG shown in Figure-1. The patient was hemodynamically stable at the time this tracing was recorded.
      • Is the rhythm in Figure-1 complete AV Block?
      • Explain your answer ...
      Figure-1: Simultaneously-recorded 3-lead rhythm strip obtained from a 75 year old woman with syncope and shortness of breath. Is this complete AV Block? Explain WHY this is (or might not be) complete AV Block. NOTE — Enlarge by clicking on Figures — Right-Click to open in a separate window.
