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.
