    150 is arbitrary — 150 is sinus. unless you see the sudden start then it’s SVT plus patient presentation will assist in interpretation.

    if you like I can send you clearer expamples. your rhythm generator leaves a bit to be desired.

      When the PR interval is greater than 0.2 sec (5 small squares) this would indicate prolonged PR interval.
      Kind regards,

    Only 2 QRS complexes then asystole thus not enuf to say the QRS rhythm is regular or irredular… there is no return of the QRS complexes thus into ventircular asystole.

    I have a question about strip number 3. With third-degree heart block, shouldn’t each beat be regular on its own, even if the atria and ventricles are beating independently? The ventricular beat should have appeared before the short strip ended. Can you provide an explanation for this?

    • ACLS says

      Third-degree block does not require that either the atrial or ventricular firing be regular. As is the case in the rhythm strip for question #3, the ventricular rate is irregular. Kind regards, Jeff
