Defibrillation is indicated only in certain types of cardiac dysrhythmias, specifically ventricular fibrillation (VF) and pulseless ventricular tachycardia. [1] [2] If the heart has completely stopped, as in asystole or pulseless electrical activity (PEA), defibrillation is not indicated. Defibrillation is also not indicated if the patient is ...
An automated external defibrillator or automatic electronic defibrillator (AED) is a portable electronic device that automatically diagnoses the life-threatening cardiac arrhythmias of ventricular fibrillation (VF) and pulseless ventricular tachycardia, [1] and is able to treat them through defibrillation, the application of electricity which stops the arrhythmia, allowing the heart to re ...
Asystole (New Latin, from Greek privative a "not, without" + systolē "contraction" [1] [2]) is the absence of ventricular contractions in the context of a lethal heart arrhythmia (in contrast to an induced asystole on a cooled patient on a heart-lung machine and general anesthesia during surgery necessitating stopping the heart).
ECG flatline or asystole is diagnosed when a person, who is in cardiac arrest (the heart stops beating), is experiencing the following conditions: unresponsive to stimuli, without breathing or a palpable pulse. [2] The eclectrocardiogram (ECG) test records the heart's electrical activity and will show a flat line if the heart stops beating. [2]
In medicine, an agonal heart rhythm is a variant of asystole. Agonal heart rhythm is usually ventricular in origin. Occasional P waves and QRS complexes can be seen on the electrocardiogram. The complexes tend to be wide and bizarre in morphological appearance. [1]
Ventricular fibrillation (V-fib or VF) is an abnormal heart rhythm in which the ventricles of the heart quiver. [2] It is due to disorganized electrical activity. [2] Ventricular fibrillation results in cardiac arrest with loss of consciousness and no pulse. [1] This is followed by sudden cardiac death in the absence of treatment. [2]
A study measured the effects of chest compression fraction on return of spontaneous circulation in out-of-hospital cardiac arrest patients with a non-ventricular fibrillation arrhythmia and it showed a trend to achieving return of spontaneous circulation with an increased chest compression fraction. [2]
Though it is nice to have the unshockable and shockable rhythms side by side, I worry that calling the VF image "asystole" in any way is more confusing than helpful. I think it's most appropriate to remove it unless the file is edited. CrashCart9 03:34, 2 October 2019 (UTC)
