Pulseless Electrical Activity - ECG

Pulseless electrical activity (PEA) is an ECG finding that must always be confirmed according to present clinical condition of the patient. Pulseless electrical activity means the situation when a patient is unconscious because of cardiac arrest and pulseless. However, there is an electrical activity in the recorded ECG that is neither ventricular tachycardia, nor ventricular fibrillation.

 

Pulseless Electrical Activity - ECGThis is ECG record of a pulseless patient during cardiac tamponade. The electrical activity in this case confirms the presence of PEA. The ECG was apparently taken about 1 hour after the cardiac arrest when cardiopulmonary resuscitation has been terminated (unsuccessfully).
 

Conclusion: The main clinical outcome is the fact that there is no effect in electric defibrillation in a patient with PEA. In addition, PEA finding is related to poor prognosis.
