  1. I hope this information will help me. As a healthcare professional, it has always been a problem when it comes to analizing cardac rhythms. this materials is well symplified.
    thank you for providing such great material free of charge.

  2. Jeff, do you have an instructional or tutorial regarding how to use a monitor….or suggestions on any I could look up? I know this may sound dumb, but not all people work with one on a regular basis. I appreciate any feedback on this. Also, thank you for this wonderful site, as it is helping me very much to understand some concepts I’ve had problems with. Thanks!

    • At this time, I do not have any tutorials for using a monitor/defibrillator. This YouTube video is a very good overview of the use of a monitor/defibrillator.
      There are a number of different varieties of monitor/defibrillators available, and each one may have a few minor different features. The best way to learn about these machines is to put your hands on them and play with them. If you have one available, I would encourage to mess around with it once or twice a month to stay familiar with its features.
      Kind regards,
      Jeff

  3. Jeff, any place on your site that explains PVC? Thank you much. Nicki

    • There is no place on the site that specifically covers PVC. A PVC is a premature ventricular contraction. The PVC is caused when the ventricle is irritated and fires without an electrical current coming from the atria to the ventricles.
      This is why PVCs always have a wide QRS complex. The electrical impulse is generated in the ventricles, unlike a normal impulse which is initially generated in the atria and travels from the atria to the ventricles.

      Kind regards,
      Jeff

      • Hi Jeff,

        I have been a nurse for a while now and worked in various ER’s for nearly 2 decades. I really wanted to say the modern approach to ACLS as a team is way better than the earlier years……..lol. For those that could use some help with rhythm interpretation there is a book titled, “Rapid Interpretation of EKG’s” , by Dr. Dale Dubin. It can be found virtually anywhere and was very helpful for me to understand what I’m seeing on that cardiac monitor and why. He is very simple in his teaching approach in the book. It will cover everything including 12 lead interpretation. I have surely recommended it to new nurses prior to their initial ACLS. Now, 20 years later, it’s still a great resource. Hope this can help some.

  4. I am so glad that there is a site dedicated for these rhythms and ACLS that is so well organized, well researched and so easy to understand. I would like to stress on the last point because tI have never been able to understand these from anywhere…and now finally I do!!! I am taking Step 2 CK next month and thanks to Jeff , I finally can go confident on these emergency medicine questions. Thank you so much Jeff !!!
