![]() An impalpable pulse should not always be taken as a pulseless electrical activity because it may be due to severe peripheral vascular abnormality.Ĭopyright © 2023, StatPearls Publishing LLC. Pulseless electrical activity can include a number of organized cardiac rhythms that may be supraventricular in origin, sinus versus non sinus, or ventricular in origin such as accelerated idioventricular or escape. Perform the initial assessment If the patient is in asystole or PEA, this is NOT a shockable rhythm Continue high-quality CPR for 2 minutes (while others are. True pulseless electrical activity is a state in which cardiac contractions are lacking in the presence of coordinated electrical impulses. There can be ventricular contractions and detectable pressures in the aorta, which are also known as pseudo-PEA. Pulseless electrical activity does not necessarily mean the lack of mechanical activity. ![]() The word “sufficient” is being used to describe a degree of ventricular mechanical activity that is adequate to generate a palpable pulse. In the case of cardiac arrest, the organized ventricular electrical activity does not usually follow sufficient ventricular response. It means that the electrical activity is pertinent, but not sufficient, condition for contraction. profound hypovolemia, airway compromise, tension pneumothorax, and pericardial tamponade). Pulseless electrical activity is formerly known as electromechanical dissociation (EMD). The resuscitation is a rapid assessment and treatment of the various measures of a Pulseless Electrical Activity (PEA) that may be caused by a traumatic etiology (i.e. A lack of ventricular impulse often points to the absence of ventricular contraction, but the contrary is not always true. Pulseless electrical activity (PEA) is defined as the presence of cardiac electrical activity with organized or partially organized cardiac rhythms without a palpable pulse. Pulseless electrical activity (PEA), also known as electromechanical dissociation, is a clinical condition characterized by unresponsiveness and impalpable pulse in the presence of sufficient electrical discharge.
