Pulseless Ventricular Tachycardia

 

Pulseless Ventricular Tachycardia

Ventricular Tachycardia

The pulseless ventricular tachycardia rhythm is primarily identified by several criteria. First, the rate is usually greater than 180 beats per minute and the rhythm generally has a very wide QRS complex.

Second, the patient will be pulseless and third, the rhythm originates in the ventricles. This is in contrast to other types of tachycardias which have origination above the ventricular tissue (in the atria).

Not all ventricular tachycardias are pulseless and therefore, pulselessness must be established prior to beginning an algorithm. This is accomplished simply by checking a carotid or femoral pulse.

Pulselessness with a tachyarrhythmia occurs because the ventricles are not effectively moving blood out of the heart and there is therefor no cardiac output. Many tachyarrhythmias of a rate >150 will deteriorate into pulselessness if timely treatment is not given.

Pulseless ventricular tachycardia is treated using the left branch of the puslesless arrest arrest algorithm. Click below to view the pulseless arrest algorithm diagram. When done click again to close the diagram.

  1. I think what MaryAnn was commiting on was on the Algorithm of PEA/Asystole it’s not a shockable, but didn’t understand once you give medication/CPR it can then become a shockable rhythm (where the yes and no arrows are).

  2. What would be the response someone would give having pulseless v-tach is occuring?

  3. very easy to understand thanks!

  4. How to differentiate between pulseless ventricular tachycardia and pulseless electrical activity?

  5. This is my second time using this site to prepare for my ACLS recertification. I find it very affordable, informative, user friendly, easy to navigate and understand. Thank you from the bottom of my Paramedic patch. Eng/PM Bill Mills

  6. So great , it is really amazing site . Thanks alot

  7. I just stumbled over this site by accident , the wealth of information and the way it is formulated is amazing . Excellent job !!!!! Thank you.

  8. great help

  9. Good web side. I have the AHA manual and after I practice in your web side, I read my aha manual.

  10. Hi,Jeff. You have under the PEA algorithm to shock if indicated. I thought PEA wasn’t shockable.

    • I could not find any reference to PEA on this page.
      There is a common misunderstanding when referring to pulseless ventricular tachycardia. Some people think that pulseless ventricular tachycardia treated as PEA.
      This is incorrect. Pulseless ventricular tachycardia is treated the same way that ventricular fibrillation is treated.
      With unsynchronized high-energy shocks.
      This is the left branch of the pulseless arrest algorithm.
      PEA and asystole are treated using the right branch of the pulseless arrest algorithm.

      Kind regards,
      Jeff

  11. I’ve been taking ACLS since its inception, and this site is certainly more interesting for the purpose of reviewing, as compared to reading the book. I find the questions and feedback from other people not only educational, but also very interesting. Thanks for a great site!
