TL;DR
Transcutaneous Pacing: External cardiac pacing for symptomatic bradycardia unresponsive to atropine.
Transcutaneous Pacing
Definition
External cardiac pacing for symptomatic bradycardia unresponsive to atropine.
Patient Communication
Communication about transcutaneous pacing in the prehospital setting includes: explaining procedures to the patient in simple terms, obtaining informed consent when possible (implied consent for unresponsive patients), providing a calm and reassuring presence, and delivering a structured handoff report (SBAR: Situation, Background, Assessment, Recommendation) to the receiving facility.
Historical Context
The modern EMS system in the United States traces to the 1966 "Accidental Death and Disability" white paper (NAS/NRC). Understanding of transcutaneous pacing has advanced significantly with evidence-based protocols. The NREMT, founded in 1970, standardized certification levels. Current ACLS and PALS guidelines are updated every 5 years by the AHA based on the International Liaison Committee on Resuscitation (ILCOR) evidence review.
Calculation Methods
Dosage calculations related to transcutaneous pacing in EMS:
- aspirin: 324mg PO chewed (PO)
- dextrose: D50W 25g IV (adult), D25W 2-4 mL/kg (peds) (IV/IO)
- adenosine: 6mg rapid IV push, then 12mg if needed (IV rapid push with flush)
Pediatric dosing: always calculate by weight (mg/kg). Use Broselow tape if weight is unknown.
Regulatory Context
Regulatory context for transcutaneous pacing includes federal and state requirements. Healthcare facilities must comply with CMS Conditions of Participation, state licensure requirements, and accreditation standards (Joint Commission or AAAHC). Non-compliance can result in citations, fines, or loss of Medicare/Medicaid reimbursement.
Safety Considerations
Field safety for transcutaneous pacing includes scene assessment before patient contact. Ensure BSI (body substance isolation) precautions are in place. PPE selection depends on the mechanism and suspected pathogens. Gloves are the minimum; add mask and eye protection for splash risk, N95 for airborne pathogens.
Never approach a scene involving hazardous materials, violence, or structural instability without proper resources and clearance from incident command.
Related Procedures
Procedures related to transcutaneous pacing in the EMS setting:
- Stroke recognition: Cincinnati Prehospital Stroke Scale (facial droop, arm drift, speech) then last known well time then transport to stroke center
- Pediatric weight-based dosing: Broselow tape for length-based weight estimation in emergencies
- RSI sequence: preoxygenation then sedation (etomidate 0.3mg/kg or ketamine 2mg/kg) then paralytic (succinylcholine 1.5mg/kg or rocuronium 1mg/kg) then intubation then confirm placement with waveform capnography
