Basically if all of the qrs look the same it is monomorphic if they look different it s polymorphic like in this strip here. A wide range of conditions may cause ventricular tachycardia and the ecg is as nuanced as are those conditions.

Acls Ventricular Fibrillation And Pulseless Ventricular Tachycardia Guide

Basically if all of the qrs look the same it is monomorphic if they look different it s polymorphic like in this strip here.

Ventricular tachycardia strip. Ventricular tachycardia is a highly nuanced arrhythmia which originates in the ventricles. Ventricular tachycardia is a pulse of more than 100 beats per minute with at least three irregular heartbeats in a row. Ventricular tachycardia may result in ventricular fibrillation and turn into sudden death.

Wellens morphology criteria for vt. So therapeutic management for ventricular tachycardia is to determine the cause and treat it it may be something so simple as an electrolyte abnormality or an mi. It is found initially in about 7 of people in cardiac arrest.

The p waves are not apparent and qrs complexes are regular. Ventricular tachycardia may impair cardiac output with consequent hypotension collapse and acute cardiac failure. It is caused by a malfunction in the heart s electrical system.

The overall heart rate. This would be called polymorphic ventricular tachycardia. Although a few seconds may not result in problems longer periods are dangerous.

The qrs complexes are 0 20 seconds. This would be called polymorphic ventricular tachycardia. The presence of pre existing poor ventricular function is strongly associated with cardiovascular compromise.

This is due to extreme heart rates and lack of coordinated atrial contraction loss of atrial kick. Wide and bizarre interpretation. So therapeutic management for ventricular tachycardia is to determine the cause and treat it it may be something so simple as an electrolyte abnormality or an mi.

Ventricular tachycardia is a type of regular fast heart rate that arises from improper electrical activity in the ventricles of the heart. In 1978 wellens et al 1 proposed the so called classical criteria to help in the differential diagnosis of supraventricular tachycardia with wide qrs complex and ventricular tachycardia. Short periods may occur without symptoms or present with lightheadedness palpitations or chest pain.

You begin your shift and assess an electrocardiogram rhythm strip. Always remember that ventricular tachycardia is the most common cause of wide qrs complex tachycardia. Pdf downloads from review ventricular tachycardia cardiac review notes ventricular tachycardia cardiac review slides cardiovascular nclex quiz questions question 1.

Not applicable qrs width. Rhythm strip 9 ecg criteria. Regardless of etiology and ecg ventricular tachycardia is always a potentially life threatening arrhythmia which requires immediate attention.
