ECG Blog #95 (ECG Video-Blog-1) – Is there AV Block?

-----------------------------------------

     I have just revised this Video (1/27/2014) — which was the first installment of my ECG Video Blog. This new version is greatly improved from my original recording on 8/16/2014 (demonstration to how much I've learned these past 5 months). Please Give Me Your Feedback (ekgpress@mac.com).

-----------------------------------------

NOTE: There are advantages to using a video format format. These include:

• Ability to illustrate concepts not done full justice by the written word.
• Greater dispersion of my content through Google & YouTube. This material is free for anyone to use.

Interpret the simultaneously-recorded 2-lead rhythm strip shown in Figure-1.

• Is AV block present on this tracing? IF so — What kind of AV block?
• Is there enough information to know for certain?
• How does one distinguish AV block from other causes of relative pauses, such as PACs (blocked or conducted) and/or Sick Sinus Syndrome?
