Rhythm: Any organized rhythm (even including VT).Extreme tachycardia, terminal bradycardia (e.g.Dependin g on the underlying cause and severity of the disease, these patients may deteriorate to full-blown cardiac arrest within a couple of minutes.The center of focus in this post is pulseless electrical activity (PEA). Non-shockable rhythm (asystole and pulseless electrical activity).ventricular fibrillation “VF” ploymorphic ventricular tachycardia “pMVT”, VT) or Rhythm: Generally, initial rhythm in cardiac arrest could be:.A brief generalized seizure or myoclonic jerks may be the initial manifestation of cardiac arrest, which can confuse the lay provider and delay the application of lifesaving BLS care.deep, slow breaths at a rate of 1-2/min) or gasping may be present immediately after the collapse, which can delay the recognition of cardiac arrest. Unresponsiveness, absence of spontaneous breathing and no palpable pulses.It is the final common pathway of all life-threatening conditions and is referred to the sudden cessation of “mechanical” cardiac activity (pump failure), as confirmed by the absence of circulation. A directed therapeutic approach to go along with aggressive resuscitation will provide patients with Pseudo PEA the best chance to survive. It is imperative for physicians to be able to distinguish pseudo-PEA from true PEA as the prognosis and man agement of these patients differ. Therefore lumping together all patients with pulseless electrical activity and treating them according to current ACLS guidelines is not appropriate. However PEA is a spectrum of disease and not all cases of PEA are in cardiac arrest state. The overall survival rate of patients with PEA is much worse than that of cardiac arrest patients with shockable rhythms. Patients with pulseless electrical activity (PEA) account for up to 30% of cardiac arrest victims. Point-of-care ultrasound in cardiac arrest.Return of spontaneous circulation (ROSC).
