Pulseless Electrical Activity (PEA) Diagnosis The ECG interpretation can appear the same as a normal sinus rhythm. Therefore in PEA, it is important to treat the symptoms of the patient and not merely the rhythm displayed on the monitor. The absence of a pulse confirms a clinical diagnosis of cardiac arrest.
What rhythms can PEA look like?
PEA encompasses a number of organized cardiac rhythms, including supraventricular rhythms (sinus versus nonsinus) and ventricular rhythms (accelerated idioventricular or escape). The absence of peripheral pulses should not be equated with PEA, as it may be due to severe peripheral vascular disease.
Is a PEA a regular rhythm?
Pulseless electrical activity (PEA) is a type of irregular heart rhythm, meaning it’s a malfunction of your heart’s electrical system. When this happens, your heart’s electrical activity is too weak to make your heart pump, which causes your heart to stop (cardiac arrest).
What does PEA look like on EKG?
Pulseless electrical activity (PEA) refers to cardiac arrest in which the electrocardiogram shows a heart rhythm that should produce a pulse, but does not. Pulseless electrical activity is found initially in about 55% of people in cardiac arrest.

Can PEA look like NSR?
Pulseless Electrical Activity (PEA) Diagnosis
An electrocardiogram (ECG/EKG) device is capable of distinguishing PEA from other causes of cardiac arrest. The ECG interpretation can appear the same as a normal sinus rhythm.
Can you pace PEA?
In many patients with bradycardic circulatory arrest (PEA), percussion pacing can replace chest compressions until pharmacological or electrical intervention shows its effect.
How would you know your patient is in PEA?
Pseudo-PEA can be detected in the absence of a palpable pulse by: arterial line placement during cardiac arrest (identified by the presence of a blood pressure) high ETCO2 readings in intubated patients. echocardiography or Doppler ultrasound demonstrating cardiac pulsatility.
Which is worse PEA or asystole?
According to International Liaison Committee on Resuscitation (ILCOR), pulseless electrical activity refers to any rhythm that occurs without a detectable pulse; however, it excludes ventricular fibrillation (VF) and ventricular tachycardia (VT). Asystole is the more life-threatening arrhythmia.
How long can PEA last?
All patients had stable vital signs at the time of disconnection from the ventilator and progressed through PEA to asystole over 12 to 21 minutes, with time to PEA being around 10 minutes.
Does PEA have a heart rate?
(Vienna, 17 April 2018) Pulseless electrical activity (PEA) is a form of cardiac arrest, whereby, despite the ECG showing an organised heart rhythm, there is no cardiac output.
Can you have a heartbeat and no pulse?
It is a type of ventricular arrhythmia or abnormal heartbeat of the ventricles. In pulseless ventricular tachycardia, the heart contracts too fast (tachycardia). This prevents the ventricles from filling with blood and stops blood flow to the body. Without blood flow, a person has no pulse.
What are the two most common causes of pulseless electrical activity?
Various causes of pulseless electrical activity include significant hypoxia, profound acidosis, severe hypovolemia, tension pneumothorax, electrolyte imbalance, drug overdose, sepsis, large myocardial infarction, massive pulmonary embolism, cardiac tamponade, hypoglycemia, hypothermia, and trauma.
Is PEA shockable rhythm?
Rhythms that are not amenable to shock include pulseless electrical activity (PEA) and asystole. In these cases, identifying primary causation, performing good CPR, and administering epinephrine are the only tools you have to resuscitate the patient.
What is pseudo PEA?
Discussion: Pseudo-PEA can be defined as evidence of cardiac activity without a detectable pulse. Distinguishing pseudo-PEA from true PEA is important for emergency physicians as the prognosis and management of these patients differ.
Is PEA The first monitored rhythm?
The first monitored rhythm is VF/VT in approximately 25% of cardiac arrests, both in- or out-of-hospital. VF/VT will also occur at some stage during resuscitation in about 25% of cardiac arrests with an initial documented rhythm of asystole or PEA.
Why do you not shock PEA?
Why not shock a PEA Arrest? In a PEA arrest, similar to Asystole, the heart doesn’t have the means to use the shock you’re sending it because the primary cause has yet to be corrected. Shocking a heart in PEA arrest is like kicking a comatose patient in the abdomen (which we do not recommend).
Do you give EPI for PEA?
When treating PEA, epinephrine can be given as soon as possible but its administration should not delay the initiation or continuation of CPR. High-quality CPR should be administered while giving epinephrine, and after the initial dose, epinephrine is given every 3-5 minutes.
How do you treat PEA rhythm?
PEA is not a shockable rhythm and treatment for PEA involves high quality CPR, airway management, IV or IO therapy, and appropriate medication therapy. The primary medication is going to be 1mg epinephrine 1:10,000 every 3-5 minutes rapid IV or IO push.
Which ECG findings are seen in pulseless ventricular tachycardia?
Electrophysiology identifying factors for pulseless ventricular tachycardia include; tachycardia (>100 bpm), wide QRS complexes (> 120 milliseconds), atrioventricular (AV) dissociation, presence of fusion or capture beats and an electrical axis between -90 to -180.
What are shockable rhythms in the pulseless patient?
The two shockable rhythms are ventricular fibrillation (VF) and pulseless ventricular tachycardia (VT) while the non–shockable rhythms include sinus rhythm (SR), supraventricular tachycardia (SVT), premature ventricualr contraction (PVC), atrial fibrilation (AF) and so on.
What happens if you shock a non shockable rhythm?
However, the only “shockable” heart rhythms are ventricular fibrillation and pulseless ventricular tachycardia. Asystole isn’t a shockable rhythm, and defibrillation may actually make it harder to restart the heart.
