EKG Practice Test 1 - Learn & Master ACLS/PALS


  1. k lewis says

    this is ventricular asystole

    if you are trying to make this fine v fib, you are attempting creativity.
    not well done

    • ACLS says

      #12 is an example that was extracted from a real rhythm strip, and it is fine ventricular fibrillation.
      Kind regards,

      Fine vfib can look very similar to asystole. coarse vfib is more obvious. I hope this helps.

    • CB says

      its actually vfib. we were taught about this type of vfib at medschool it looks too similar to asystole at first glance

    • ACLS says

      The atria and the ventricles are not synchronized. They are disassociated and there is no coordination between the upper and lower chambers of the heart. Kind regards, Jeff


    The answer to V FIB is incorrect. It is either asystole (no defined waveform or PEA.

    • ACLS says

      These are all practice test to help you learn to identify specific rhythms you will encounter within advanced, cardiac life support

    • ACLS says

      All medications given during cardiac arrest that are given IV push need to be followed with 20 mL of NS.

      All medications given in ACLS Emergencies should be followed with 20 mL of NS.

      Kind regards,

    It is Afib. There is no p waves, so no PR interval. The rhythm is irregular and without p waves, the rhythm is Atrial Fibrillation

    Thank you so much! Studying for my final exam in my last semester of nursing and I can FINALLY INTERPRET STRIPS, THANKS TO YOU!!! Much appreciated. Keep up the good work.

    • Tim says

      Ma’am. Please don’f forget to look at and monitor your patient while watching your machines………. Good Luck

  5. Susan L says

    Thank you so much for creating this site and practice test on how to read and understand EKG strips and what is going on in the heart.

    • ACLS says

      This course is not considered the first part of ACLS. This course is strictly for training purposes to help people prepare for the American heart Association ACLS provider course. Kind regards, Jeff

    • Bobbie J Johnson says

      I just wanted to brush up on rhythm strips because I’m in school and soon will be applying for for monitor tech as soon as I get certified

  6. Chris says

    The one described to be a first-degree AV block appears to have the PR interval at less than 0.20 seconds, and all other parts of interpretation look normal (rate, rhythm, other intervals, etc.), so is this really a first-degree AV block or an odd presentation of a normal sinus rhythm? I personally do not know, and perhaps I measured wrong. Thank you.
