Asystole

Asystole is the complete absence of electrical activity in the heart, resulting in a flatline on an electrocardiogram (ECG or EKG).

This indicates a lack of cardiac mechanical function and the absence of cardiac output, leading to the cessation of blood flow.

Asystole represents the end-stage of many cardiac emergencies and is usually associated with a poor prognosis.

It necessitates immediate advanced life support interventions to attempt resuscitation. Identifying and addressing underlying causes are also essential. .

Asystole meaning with examples

• During the code, the patient's ECG showed Asystole, a flatline indicating no electrical activity in the heart. CPR and epinephrine were immediately initiated.
• Despite aggressive resuscitation efforts including drug administration, the patient remained in asystole. The medical team discussed the poor prognosis.
• After the initial shock of ventricular fibrillation failed to convert the patient, the ECG deteriorated to Asystole, prompting the use of alternative strategies.
• The emergency physician, after the administration of epinephrine and atropine, noted Asystole, meaning the heart had no electrical activity, which brought the chance of life to a low percentage.
