Pulseless Electrical Activity Ecg Strip Ventricular fibrillation, pulseless electrical activity (pea) and sudden cardiac arrest. this chapter will focus on ventricular fibrillation and pulseless electrical activity (pea). these are highly lethal arrhythmias that lead to death if cardiopulmonary resuscitation is not started immediately. The cardiac arrests with shockable rhythms are ventricular fibrillation and pulseless ventricular tachycardia. both of those can turn into pea, but pea itself isn’t shockable. however, cpr for pulseless electrical activity can sometimes get your heart to switch to a shockable rhythm.
Ventricular Fibrillation Pulseless Electrical Activity And Sudden The littman algorithm use ecg waveform and echo findings to help stratify likely causes (littman et al, 2014): step 1: determine if the pea is narrow (qrs duration <0.12) or wide (qrs duration ≥0.12) on ecg monitor. step 2: narrow complex pea is generally due to mechanical problems caused by right ventricular inflow or outflow obstruction. Ventricular fibrillation (vf) is the most important shockable cardiac arrest rhythm. the ventricles suddenly attempt to contract at rates of up to 500 bpm; this rapid and irregular electrical activity renders the ventricles unable to contract in a synchronised manner, resulting in immediate loss of cardiac output. Four rhythms produce pulseless cardiac arrest: ventricular fibrillation (vf), rapid ventricular tachycardia (vt), pulseless electrical activity (pea), and asystole. survival from these arrest rhythms requires both basic life support (bls) and advanced cardiovascular life support (acls). The majority of cardiac arrests are attributable to nonshockable rhythms. 1, 2, 3 data from the national registry of cardiopulmonary resuscitation, reporting on 51 919 in‐hospital arrests, found only ≈24% had an initial rhythm of ventricular tachycardia (vt) or ventricular fibrillation (vf), whereas the remaining 37% and 39% had pulseless electrical activity (pea) or absence of electrical.

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. a lack of ventricular impulse often points to the absence of ventricular contraction, but the contrary is not always true. it means that the electrical activity is pertinent, but not. Sudden cardiac arrest is a sudden state of circulatory failure due to a loss of cardiac systolic function. it is the result of 4 specific cardiac rhythm disturbances: ventricular fibrillation, pulseless ventricular tachycardia (vt), pulseless electrical activity, and asystole. torsades de pointes is a sub group of polymorphic vt in patients.
