How can you tell if rhythm is shockable?

A shockable rhythm was defined as disorganized rhythm with an amplitude > 0.1 mV or, if organized, at a rate of > or = 180 beats/min. Wavelet-based transformation and shape-based morphology detection were used for rhythm classification.

How do you know if rhythm is shockable?

A shockable rhythm was defined as disorganized rhythm with an amplitude >0.1 mV or, if organized, at a rate of ≥180 beats/min. Wavelet-based transformation and shape-based morphology detection were used for rhythm classification.

What are the 4 shockable rhythms?

Shockable Rhythms: Ventricular Tachycardia, Ventricular Fibrillation, Supraventricular Tachycardia.

Which rhythms are shockable and which are not?

The two shockable rhythms are ventricular fibrillation (VF) and pulseless ventricular tachycardia (VT) while the non–shockable rhythms include sinus rhythm (SR), supraventricular tachycardia (SVT), premature ventricualr contraction (PVC), atrial fibrilation (AF) and so on.

What rhythms are shockable and why?

Shockable rhythms include ventricular fibrillation and pulseless ventricular tachycardia. The ECG algorithm (at end of document) can help you determine the proper steps. End tidal CO2 (ETCO2) should be used as soon as the patient is intubated. ETCO2 is a useful indicator of cardiac output during CPR.

Do you shock VT with a pulse?

Abstract. Under current resuscitation guidelines symptomatic ventricular tachycardia (VT) with a palpable pulse is treated with synchronised cardioversion to avoid inducing ventricular fibrillation (VF), whilst pulseless VT is treated as VF with rapid administration of full defibrillation energy unsynchronised shocks.

What rhythms do you defibrillate?

The term defibrillation is usually applied to an attempt to terminate a nonperfusing rhythm (e.g., ventricular fibrillation or pulseless ventricular tachycardia).

Why do you not shock asystole?

High-quality CPR is the mainstay of treatment and the most important predictor of a favorable outcome. Asystole is a non-shockable rhythm. Therefore, if asystole is noted on the cardiac monitor, no attempt at defibrillation should be made.

What rhythms require synchronized cardioversion?

Synchronized cardioversion is used to treat other arrhythmias, including atrial fibrillation (AF), atrial flutter, and stable ventricular tachycardia when medications have failed to convert the rhythm, or when the patient is becoming unstable and the rhythm must be immediately terminated.

What does VF look like on an ECG?

It has an appearance on electrocardiography of irregular electrical activity with no discernable pattern. It may be described as ‘coarse’ or ‘fine’ depending on its amplitude, or as progressing from coarse to fine V-fib.

What is the difference between VF and VT?

VF and pulseless VT are both shockable rhythms. The AED cannot tell if the individual has a pulse or not.
(Irregular Wide Complex Tachycardia)

Regularity There is no regularity.
QRS Complex The ventricle complex varies.

What is VT and VF?

What is Ventricular Arrythmias (VT, Ventricular fibrillation VF) Ventricular Arrythmia (VA) is a severely abnormal heart rhythm (arrhythmia) that, unless treated immediately, causes death. VF is responsible for 75% to 85% of sudden deaths in persons with heart problems.
