Like with Asystole, an AED will not correct this arrhythmia, and CPR should be administered as soon as possible to provide the best patient outcome.ĪEDs are a vital component in response to cardiac emergencies, and they are the proven therapy for both V-Tach and V-Fib. In PEA, the heart’s electrical activity is too weak to continue pumping blood throughout the body. PEA -yet another type of irregular heartbeat caused by an electrical problem in the heart.If an Asystole rhythm is detected by an AED, it will not shock the patient, as defibrillation is not a viable treatment here. Asystole can be the result of untreated VT or VF. If someone experiences Asystole, CPR should be initiated immediately to provide the best chances of survival. An Asystole - rhythm means that the heart’s electrical system has shut down and there is no heartbeat.is hypotensive, AMS, shock, ischemic CP, or acute HF. Synchronized cardioversion is indicated if the pt. Most interestingly was the discovery that intracranial hemorrhage, in 80% of cases subarachnoid hemorrhage, was the underlying precipitant of PEA in almost 7% of all cases 1. with regular narrow-complex QRS at a rate >150bpm in which vagal maneuvers are ineffective should be given 6mg adenosine IV. ![]() Other cardiac dysrhythmias, such as long QT syndrome, were also common etiologies. Acute coronary syndrome was cited as the primary cause in 12.5% cases. toxins: includes carbon monoxide, opioids, methadone, benzodiazepinesĪ recent large retrospective Swiss study reviewing 1,866 out-of-hospital cardiac arrests (over a 10-year-period) demonstrated that the most frequent cause of pulseless electrical activity was hypoxia, accounting for almost 25% of all cases.Full list of risk ratios with 95 confidence intervals is provided. Analyses are presented as risk ratios with 95 confidence intervals. PEA: pulseless electrical activity, CI: confidence interval. Forest plot of risk factors associated with PEA and asystole. cardiac (ACS) or pulmonary embolism (PE) Download : Download high-res image (622KB) Download : Download full-size image Fig.Pathology EtiologyĬlassically the etiologies have been described as the 4 Hs and 4 Ts 1: ventricular tachycardia/fibrillation), but no measurable cardiac output. Lack of output may be recognized by the absence of any arterial pulse or systolic blood pressure 1,2. It is characterized by the presence of cardiac electrical activity, which may be organized or disorganized, in the absence of a ventricular tachyarrhythmia (i.e. Pulseless electrical activity is one of the possible states found in an unconscious patient who has had a cardiac arrest. ![]()
