ventricular fibrillation pulseless electrical activity ecg

Treatment includes reversing the cause of cardiac arrest, in addition to providing assisted ventilation and chest compression. Pulseless electrical activity (PEA) is organized cardiac electrical activity without associated mechanical activity. Antiarrhythmic medications, such as amiodarone and lidocaine, or defibrillation are not considered during neonatal CPR mainly because shockable arrhythmias such as VF and pulseless ventricular tachycardia (pVT) have not been recognized in newborn infants with cardiac arrest. In the neonatal subpopulation, even less direct evidence exists, and guidelines for neonatal resuscitation are rather simplified compared to adult guidelines e.g., adrenaline (epinephrine) is the only drug in the neonatal resuscitation algorithm. When direct evidence is lacking, guidelines for paediatric CPR are developed with consideration of the evidence from adults. However, in observational studies, VF was diagnosed as the initial rhythm in 4–19% of paediatric cardiac arrests. Therefore, the initial focus for paediatric OHCA has been on rescue breathing and chest compressions whereas rhythm diagnosis and defibrillation have received less emphasis. In contrast, paediatric cardiac arrest is usually of respiratory aetiology, and the initial rhythm is often non-shockable including asystole and pulseless electrical activity (PEA). Thus, rhythm diagnosis and defibrillation are important features of adult cardiopulmonary resuscitation (CPR). Pulseless ventricular tachycardia (pVT) ECG,Īdult out-of-hospital cardiac arrests (OHCA) are commonly of primary cardiac origin with ventricular fibrillation (VF) as the cause of arrest.
