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. SICD tracings show oversensing of widened QRS just prior to. However, heart function is still too weak to pump enough blood to meet the body’s demands. Ultimately the patient experienced pulseless electrical activity (PEA) arrest and CPR was initiated. Pseudo-PEA describes electrical activity that can still cause the heart to contract slightly and pump some blood. PEA may take two similar but distinct forms: pseudo-PEA and true 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)? While PEAs can’t always be prevented, maintaining good cardiovascular health and working with a doctor if you have any type of arrhythmia or other heart condition may help lower your risk. PEAs often stem from other heart problems, such as a heart attack, or other physical trauma. PEA is considered a medical emergency that requires immediate CPR and other treatments. PEAs can progress to sudden cardiac arrest if not treated. It occurs when the electrical activity in your heart is too weak to maintain a heartbeat or to pump blood through your body. Pulseless electrical activity (PEA) is a type of abnormal heart rhythm. They often stem from other heart problems, such as a heart attack, or other physical trauma. They can be mild and relatively harmless or severe and life threatening. The beating of your heart is powered by an electrical system that maintains a steady rhythm of contractions and rests 24 hours a day.Ībnormal rhythms are called arrhythmias. PEA can be a precursor to sudden cardiac death, so its symptoms require immediate medical attention. Pulseless electrical activity (PEA) is an especially serious heart arrhythmia related to weak or undetectable electrical activity.
