![]() ![]() Asystole and pulseless electrical activity account for up to 70 of all out-of-hospital cardiac arrests encountered by EMS 576, 577 and has a dreadful prognosis. Asystole or pulseless electrical activity. Initial medical therapy may include afterload reduction using nitrates, sodium nitroprusside, and diuretics in case of adequate blood pressure. OPIE, in Drugs for the Heart (Eighth Edition), 2013. Prompt initiation of medical therapy and emergent surgery are necessary for a favorable outcome in patients with papillary muscle rupture. It usually occurs two to seven days after the infarct. ![]() Papillary muscle rupture is a life-threatening complication that accounts for approximately 5 percent of deaths in these patients. Many patients do not survive the acute phase because of the development of immediate cardiogenic shock and pulseless electrical activity. If the patient stabilizes and bleeding stops, a conservative approach might be justified in selected cases however, immediate cardiac surgery should be considered. In patients with suspected or diagnosed free wall rupture, emergency pericardiocentesis is indicated if fluid is visualized. Survival depends primarily upon the early recognition and provision of immediate therapy. In selected stable patients with subacute or covered rupture, cardiac magnetic resonance imaging may be used for differential diagnosis and preoperative planning. Emergency pericardiocentesis, when performed in a patient with acute cardiogenic shock and suspected free wall rupture, may confirm the diagnosis. The echocardiogram typically shows pericardial effusion with evidence of chamber compression and may also be able to show the rupture itself. Tension pneumothorax.The diagnosis of free wall rupture is based on clinical and echocardiographic signs of pericardial tamponade. Pseudo-pulseless electrical activity in the emergency department, an evidence based approach. The role of toxic substances in sudden cardiac death.

Healthline has strict sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical associations. It also means no blood is being pumped into or out of the heart. True PEA means there is faint electrical activity in the heart, but not enough to make it contract or produce a detectable pulse. This may be due, in part, to significantly less research on pseudo-PEA than true PEA. Because a pulse can’t be found, only an electrocardiogram (EKG) can identify the reduced electrical flow in the heart.Ī 2020 study suggests that the incidence of pseudo-PEA is increasing and that it may be more common than previously estimated. However, heart function is still too weak to pump enough blood to meet the body’s demands. Pseudo-PEA describes electrical activity that can still cause the heart to contract slightly and pump some blood. The most likely cause is severe myocardial. PEA may take two similar but distinct forms: pseudo-PEA and true PEA. PEA: pulseless electrical activity, CI: confidence interval. Absence of a pulse in the presence of good electrical capture constitutes pulseless electrical activity (PEA). PEA is an arrhythmia in which the heart’s electrical activity has become so weak, it can’t make the heart contract effectively and a pulse is impossible to detect. What is pulseless electrical activity (PEA)?
