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.
This 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.
