Ventricular Tachycardia Management

All About Cardiovascular System and Disorders

Ventricular tachycardia is a potentially life threatening cardiac arrhythmia. On the ECG, ventricular tachycardia can be defined as three or more ventricular ectopic beats occurring in a sequence at a rate more than 100 per minute. Another rare form of ventricular tachycardia is bidirectional ventricular tachycardia.

Instructors' Collection ECG: Regular Really Wide QRS Tachycardia

ECG Guru

The ECG : The first impression is that is a regular WIDE COMPLEX TACHYCARDIA. It pays to take a moment to consider the possibility of REGULAR REALLY WIDE COMPLEX TACHYCARDIA (RRWCT) before making a treatment decision. So, we can assume the patient was probably being treated for angina, heart failure, and hypertension.

SUSTAINED VENTRICULAR TACHYCARDIA

ECG Guru

We see here a wide complex tachycardia with a frequency of approx. The short VT after the end of the sustained ventricular tachycardia with the same QRS morphology also indicates a ventricular origin of this arrhythmia. 105-110 beats per minute that lasts for a good minute.

Then I always look to see if the initial deflection of the QRS has a lot of voltage change per change in time (seen in tachycardias that are initiated from above the ventricle because the propagate through fast conducting purkinje fiber.

Here is the 12-lead ECG: Wide complex tachycardia What do you think? His pulse on the monitor suddenly went down to 140 and another 12-lead ECG was recorded: Sinus tachycardia at a rate of 143 There are peaked T-waves typical of hyperkalemia The K returned at 6.9 Blood pressure was 117/80, pulse 161, Resp 45, SpO2 100 on oxygen.

Ventricular Tachycardia

There are several differential diagnoses in the presence of broad-complex tachycardia. The most common cause of wide-complex tachycardia is ventricular tachycardia. In 2nd place is sinus tachycardia/supraventricular tachycardia with aberrant conduction or preexisting bundle branch block.
