These are complete, residency/DM-level notes built from base to top. Here's a quick orientation to the structure:
The 18 sections progress logically:
- Device classification (what each CIED is)
- Hardware anatomy (PG, leads, electrodes)
- NBD pacing code (understand any programmed mode)
- Sensing & capture physics (strength-duration curve, chronaxie, threshold maturation)
- Rate-responsive pacing (sensors, chronotropic incompetence)
- Hemodynamics of pacing (AV synchrony, pacing site effects, His/LBBAP)
- Pacemaker indications (SND, AV block, bifascicular, hypersensitive carotid - Class I/II)
- Pacemaker troubleshooting (failure to pace, loss of capture, over/undersensing, PMT, runaway pacemaker)
- ICD types (TV-ICD, S-ICD, EV-ICD, WCD) + shock physics
- ICD therapy zones (ATP, cardioversion, defibrillation, detection zones)
- ICD indications (secondary prevention meta-analysis; primary prevention trials: MADIT, SCD-HeFT, DANISH, with key LVEF/QRS thresholds)
- CRT (mechanism, indications, key trials with data: CARE-HF, COMPANION, MADIT-CRT, RAFT, ECHO-CRT)
- Leadless, S-ICD, CSP/HBP/LBBP (emerging tech)
- Complications (procedural + long-term including infection management)
- EMI (MRI, cautery, magnet behavior)
- ICD troubleshooting (inappropriate shocks, VT storm algorithm)
- Remote monitoring, special situations (pregnancy, perioperative, end-of-life, TLE)
- High-yield exam pearls (table format)
