Transcutaneous pacing

Background

Indications

  • Bradyarrhythmias causing hemodynamic impairment:[1]
    • AV block
    • Sinus node dysfunction
    • A-fib with slow ventricular response
    • Malfunction of implanted pacemaker
  • Tachyarrhythmias causing hemodynamic impairment[1]

Procedure

True electrical capture
False capture with visible phantom beats[2]
  • Pad placement:
    • Pad on apex of heart and on right upper chest
    • Pad on lead V3 position and between left scapula and T-spine
  • Set: HR 80, pacing threshold usually between 40-80 mA
    • Look for clear QRS complex and T-wave following pacer spike
    • Check pulse to confirm mechanical capture
    • Final current set 5-10 mA above threshold level for patient
