PEA is one of many waveforms by ECG (including sinus rhythm) without a detectable pulse. PEA may include any pulseless waveform with the exception of VF, VT, or
What rhythm is PEA?
Pulseless electrical activity (PEA) is a condition where your heart stops because the electrical activity in your heart is too weak to make your heart beat. When your heart stops, you go into cardiac arrest, and you don’t have a pulse. PEA is a “nonshockable” heart rhythm, meaning a defibrillator won’t correct it.
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.
What causes PEA rhythm?
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.
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 long can PEA rhythm last?
Recent studies have shown that 5.8–6.8% of PEA patients are alive 30 days after resuscitation[7, 11]. The long-term outcome of patients resuscitated from PEA is unknown, whereas the long-term outcome of patients with VF as initial rhythm is well documented[12].
Can peas be sinuses?
PEA is one of many waveforms by ECG (including sinus rhythm) without a detectable pulse. PEA may include any pulseless waveform with the exception of VF, VT, or asystole (Figure 28).
What is the difference between PEA and asystole?
Asystole is the flatline reading where all electrical activity within the heart ceases. PEA, on the other hand, may include randomized, fibrillation-like activity, but it does not rise to the level of actual fibrillation.
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.
How do you treat PEA rhythm?
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.
What is the most common cause of pulseless electrical activity?
Respiratory failure leading to hypoxia is one of the most common causes of pulseless electrical activity, responsible for about half of the PEA cases.
When does PEA occur?
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.

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?
Epinephrine should be administered in 1-mg doses intravenously/intraosseously (IV/IO) every 3-5 minutes during pulseless electrical activity (PEA) arrest.
Is complete heart block sinus rhythm?
Sinus rhythm with third degree (complete) heart block. There is independent atrial (as shown by the P waves) and ventricular activity, with respective rates of 83 and 43 beats per minute. The wide QRS complexes may represent a junctional escape rhythm with underlying bundle branch block or an idioventricular pacemaker.
Can a stroke cause PEA?
There is an association between all causes of cardiac arrest and ischemic stroke, but this occurs in fewer than 4% of cases [2]. A direct correlation between PEA arrest and BAO has not been reported in detail before. However, the deficits due to brainstem dysfunction may increase the risk of PEA arrest.
What is pea?
Pulseless electrical activity (PEA) is a clinical condition characterized by unresponsiveness and the lack of a palpable pulse in the presence of organized cardiac electrical activity.
What are the 4 shockable rhythms?
The four arrest rhythms seen are asystole, pulseless electrical activity, ventricular fibrillation and pulseless ventricular tachycardia. These can be divided into non-shockable and shockable rhythms. Non- shockable rhythms include asystole and pulseless electrical activity.
What are the 2 shockable rhythms?
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.
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.
