Classification1 / 4
- passive = escape rhythm from slow SAN = next fastest pacemaker
- active = ⬆activity in junctional pacemaker
Pathophysiology2 / 4
- AV junction intrinsic rate is 40-60 bpm
- originate from AVN
- low RA + coronary sinus, AVN, bundle of His
- difficult to determine exact origin
- below SAN = retrograde conduction
- inverted P waves
- often lose in larger QRS
Management3 / 4
- treatment rarely needed
Anaesthetic considerations4 / 4
- Pre-op
- Intra-op
- Post-op
