Overview
Pulseless electrical activity (PEA) is defined as the presence of spontaneous organized cardiac electric activity in the absence of blood flow sufficient to maintain consciousness and absence of a rapid spontaneous return of adequate organ perfusion and consciousness.
Causes
Life Threatening Causes
Pulseless electrical activity is a life-threatening condition and must be treated as such irrespective of the causes. Life-threatening conditions can result in death or permanent disability within 24 hours if left untreated.
Common Causes
The complete list of causes of PEA can be remembered using the mnemonic "The Hs and Ts".[1][2][3]
- Hypovolemia
- Hypoxia
- Hydrogen ions (Acidosis)
- Hypothermia
- Hyperkalemia or Hypokalemia
- Hypoglycemia
- Tablets or Toxins (Drug overdose) such as beta blockers, tricyclic antidepressants, or calcium channel blockers
- Tamponade
- Tension pneumothorax
- Thrombosis (Myocardial infarction)
- Thrombosis (Pulmonary embolism)
- Trauma (Hypovolemia from blood loss)
- Covid-19
As noted by repeated balloon inflations in the cardiac catheterization laboratory, transient occlusion of the coronary artery does not cause PEA.
Management
Below is an algorithm summarizing the approach to a patient with pulseless electrical activity.[4]

The algorithm is based on the 2010 American Heart Association ACLS algorithm for PEA.[6]
Do's
- Efficiency of CPR can be determined by
- Monitoring of chest compression rate and depth
- Adequacy of chest wall relaxation
- Length and duration of pauses in compression and number and depth of ventilations delivered
- Physiologic parameters; partial pressure of end-tidal CO2 [PETCO2], arterial pressure during the relaxation phase of chest compressions, central venous oxygen saturation [ScvO2]
- Remember that the foundation of successful ACLS is good BLS , represented in prompt high-quality CPR with minimal interruptions.[7][8]
- A new class I recommendation is the use of quantitative waveform capnography for confirmation and monitoring of endotracheal tube placement.
- Supraglottic advanced airways continues to be an alternative to endotracheal intubation for airway management during CPR.
Don'ts
- Don't routinely use cricoid pressure during airway management of patients in cardiac arrest.
- Don't administer atropine in the management of pulseless electrical activity as it is no longer recommnded.
