We don’t “shock” asystole, aka a “flatline” heart rhythm. We do manual chest compressions and we give them epinephrine (adrenaline) and we *hope* that restarts their heart (along with a ...
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).
Pulseless electrical activity (PEA) is a form of cardiac arrest in which the electrocardiogram shows a heart rhythm that should produce a pulse, but does not.Pulseless electrical activity is found initially in about 20% of out-of-hospital cardiac arrests [1] and about 50% of in-hospital cardiac arrests.
In children, the most common cause of cardiac arrest is shock or respiratory failure that has not been treated. [30] Cardiac arrhythmias are another possible cause. Arrhythmias such as asystole or bradycardia are more likely in children, in contrast to ventricular fibrillation or tachycardia as seen in adults. [30]
Defibrillation is effective only for certain heart rhythms, namely ventricular fibrillation or pulseless ventricular tachycardia, rather than asystole or pulseless electrical activity, which usually requires the treatment of underlying conditions to restore cardiac function. Early shock, when appropriate, is recommended.
Death can occur from any shock that carries enough sustained current through a vital organ or tissue. When an electric current flows through the brain or spinal cord , death due to asphyxiation may occur as a result of interference with the central nervous system 's control of respiration, or through direct paralysis of the chest muscles.

Initial symptoms may include heart asystole and respiratory arrest. [1] While the asystole may spontaneously resolve fairly rapidly, the respiratory arrest is typically more prolonged. [1] Other symptoms may include burns and blunt injuries. [1] Of those who survive, about 75% have ongoing health problems as a result, such as cataracts and ...
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]
