, 1. Fundamental Electrophysiology
• Know functional anatomy: sinus node, AV node, His-Purkinje system, Bachmann bundle, right atrial/ventricular structures,
coronary sinus and cardiac veins.
• Understand re-entry, sinus-node dysfunction, AV block, bundle-branch disease and tachyarrhythmia mechanisms.
• Recognize how ischemia, fibrosis, inflammatory/infiltrative disease and other pathology can impair conduction.
• Connect electrical dyssynchrony with heart-failure physiology and understand the rationale for CRT and conduction-system
pacing.
2. Engineering & Electrical Concepts
• Know ampere, volt, ohm, charge and hertz.
• Use Ohm's law conceptually: voltage, current and resistance are interrelated.
• Review power, energy, capacitance, battery capacity and charge time.
• Know pulse-generator components including capacitors, resistors, diodes and sensors.
• Review accelerometer, minute-ventilation and thoracic-impedance sensors.
• Know lead insulation, conductors, connectors and electrodes; recognize IS-1, DF-1, DF-4 and LV-4.
• Understand pacing and defibrillation vectors and the basic distinction between unipolar and bipolar systems. ■cite■turn1view0■
3. Device Technology & Design
• Understand intracardiac electrograms, sensing amplifiers, filters, slew rate, far-field and cross-chamber signals.
• Recognize extracardiac signals such as myopotentials, electromagnetic interference, electrocautery, TENS and other sources.
• Understand cathode/anode stimulation, pacing thresholds, defibrillation thresholds and acute-to-chronic threshold changes.
• Review S-ICD versus transvenous ICD concepts, including limitations, vectors and defibrillation considerations.
4. Device Functions & Algorithms
• Master pacing modes, rate response, mode switching, autocapture, noncompetitive atrial pacing and upper-rate behavior.
• Understand tachyarrhythmia detection, ATP, SVT discrimination and ICD therapy logic.
• Review CRT programming: AV/VV timing, multipoint pacing, offset and anodal stimulation.
• Know physiologic pacing concepts including His-bundle pacing and left-bundle-area pacing.
• Review leadless pacing timing and device-specific considerations. ■cite■turn1view0■
5. Electrocardiography
• Interpret normal paced rhythms and use morphology as one clue to pacing location.
• Recognize device malfunction patterns and distinguish true malfunction from pseudo-malfunction.
• Review upper-rate behavior, AV hysteresis, rate hysteresis, MVP-type behavior, reverse mode switching and sleep mode.
• Recognize device-mediated rhythms, native dysrhythmias and wearable-monitor artifact.
6. Clinical Assessment & Device Indications
• Take a device-centered history: symptoms, medications, prior arrhythmia, implant indication, implant/revision history,
abandoned leads and prior device response.
• Assess pacemaker dependence, pacing burden and ventricular/atrial arrhythmia history.

, • Examine the pocket and wound for infection, healing problems and venous-occlusion clues.
• Know broad indications for pacing, ICD therapy, implantable loop recorders and heart-failure device therapy.
• Review drug-device interactions, antiarrhythmics, QT-prolonging agents and peri-procedural anticoagulation.
■cite■turn1view0■
7. Perioperative & Intraoperative Practice
• Review consent, documentation, chart review and device history before procedures.
• Understand venous access, lead placement, coronary sinus cannulation, epicardial systems, physiologic pacing sites and
antibiotic envelopes.
• Review sedation/monitoring principles and intraoperative threshold/defibrillation testing concepts.
• Know extraction concepts and tools such as locking stylets, powered sheaths, snares and bridge-balloon rescue.
• Recognize congenital/structural anatomy that can alter implantation strategy.
8. Safety
• Understand risks from electrocautery, electromagnetic interference, MRI and external defibrillation.
• Before a procedure, identify device type, patient dependence, system status and the exact procedural exposure.
• Do not assume every CIED is safe for every MRI condition; verify the exact system and current requirements.
• Know infection-prevention principles and escalation for suspected device infection.
9. Radiology
• Recognize lead positions on chest radiography and fluoroscopy.
• Review coronary venous anatomy relevant to LV lead placement.
• Use CT concepts for suspected lead perforation or unusual lead location.
• Recognize echocardiographic pericardial effusion and abnormal lead-location clues. ■cite■turn1search12■
10. Patient & Device Follow-Up Management
• Prioritize interrogation, programming, diagnostics and troubleshooting because this is the highest-weight domain.
• Evaluate rhythm and therapy, rate modulation, hemodynamics, pacemaker syndrome and CRT performance.
• Know generator longevity, ERI/EOL, lead maturation and leadless-pacing follow-up.
• Troubleshoot oversensing, undersensing, failure to capture, anodal capture and phrenic nerve stimulation.
• Interpret stored episodes, mode switches, atrial/ventricular arrhythmias, PMT, percent pacing, arrhythmia burden and rate
histograms.
• Recognize venous/anatomical complications, infection and mechanical complications such as Twiddler syndrome.
• Understand remote monitoring concepts, alerts, connectivity and device diagnostics. ■cite■turn1search13■turn1search12■
