Cardiac Arrest - ECG

Total cardiac arrest manifests in the ECG curve as the isoelectric line present in all leads. A similar finding in only one lead is usually caused by  poor contact between the electrode and the patient’s skin.

 

Cardiac Arrest - ECGThis ECG records a transition of heart rhythm into the cardiac arrest.
 

Conclusion: Confirming the cardiac arrest is important during cardiopulmonary resuscitation. In such case we do not carry the electrical defibrillation (unlike ventricular fibrillation) and the resuscitation must consist of cardiac massage, ventilation, and administration of certain drugs.
