Overview
The administration of beta blockers and calcium channel blockers is associated with an increased risk of PEA. This may be due to their effect on the interactions between calcium and troponin and their inhibition of myocardial contractility. Syncope and pulmonary disease is also associated with a higher risk of PEA.[1]
Risk Factors
Beta Blockers and Calcium Channel Blockers as Risk Factors for PEA
It is not yet well established why beta blockers and ACE inhibitors are risk factors for PEA. One possible explanation is that the use of beta blockers and ACE inhibitors in the context of ventricular fibrillation might lead to the conversion of ventricular fibrillation (VF) to pulseless electrical activity (PEA).[7] Another explanation for the association is that the pharmacological treatment with beta blockers and ACE inhibitors of patients with VF have lead to a decrease in the prevalence of VF and subsequent relative increase in the incidence of PEA among patients with SCA.[8] [9]
