What's up guys? Today we're going to talk about ventricular tachy. We're going to go over the definition, how to identify this rhythm on the EKG, the atology, patient presentation, and how do we treat these patients? Ventricular tachocardia can be broken down

into many different types, such as non-sustained

monomorphic ventricular tachocardia,

sustained monomorphic ventricular tachocardia,

and polymorphic ventricularler Tachycardia.

First let's talk about how to define non-sustain ventricular tachycardia and keep in mind

there are varying opinions on the best definition but we will go over the most commonly

used definition today. In non-sustained ventricular

tachocardia, you will have three or more consecutive premature ventricular contractions,

a heart rate greater than 100 beats per minute and a duration lasting less than 30

seconds. So here you can see a 5-beat run of non-sustained ventricular

tachochardia with a heart rate of about 165 beats per minute and lasting less than 30 seconds.

Sustain monomorphic ventricular tachycardia can be defined by the following

characteristics. A regular

wide QRS complex greater than 120 milliseconds

with a heart rate greater than 100 beats per minute.

The arrhythmia will last greater than 30 seconds

or cause hemodynamic collapse in less than 30 seconds.

It will also have consecutive

and trickler beats that have a uniform and stable QRS morphology. So here you can

see a regular wide QRS complex at around 160 milliseconds with a heart rate of about 300

beats per minute and this would have to last longer than 30 seconds or cause
