EP Videos Mapping Certification Exam Questions With Answers
SA Node - ANSWER- Area of cells in the right atrium with automatic depolarization
AV Node - ANSWER- Connects atria to ventricles, creates delay for coordinated blood flow
Bundle of His - ANSWER- Includes right and left bundle bran...
IntellaNav MiFi - ANSWER- Catheter measuring impedance around the tip for insights
Direct Sense Technology - ANSWER- Measures sub-surface temperature and local
impedance during RF delivery
Irrigated Catheters - ANSWER- Decrease thrombus risk, commonly used in RF ablation
, Contact Force - ANSWER- Determines lesion depth, optimal range between 10-20
grams
Steam Pop - ANSWER- Tissue overheating causing catheter to puncture myocardium
Phrenic Nerve Injury - ANSWER- Risk during Cryoablation, may lead to breathing
difficulty
Esophageal Fistula - ANSWER- RF catheter burns through LA wall to esophagus, life-
threatening
Cryoablation - ANSWER- Uses cold energy to create non-conductive tissue in
pulmonary veins
Activation Map - ANSWER- Shows timing of electrical events in heart to identify
arrhythmia origins
Voltage Map - ANSWER- Translates signal amplitudes to colors for scar identification
Rhythmia HDx - ANSWER- Requires BSC Orion or Intella for continuous mapping
IntellaMap ORION - ANSWER- Creates HD electroanatomic maps with 64 electrodes
Biophysics of RF - ANSWER- RF ablation circuit components and impedance
importance
Impedance - ANSWER- Return path for ablation energy, crucial for circuit assessment
Mechanism of RF - ANSWER- RF generator produces high-frequency energy for
ablation
Electrode-tissue interface - ANSWER- The area where the catheter contacts the
myocardium, crucial for lesion formation due to resistive heating.
Resistance - ANSWER- Impedance that forms heat crucial for lesion formation during
catheter ablation.
Lesion - ANSWER- Irreversible tissue damage created by resistive and conductive
heating during ablation.
Resistive heating - ANSWER- Initial lesion formation through heat generation at the
electrode-tissue interface.
Conductive heating - ANSWER- Formation of the bulk of the lesion volume as heat
dissipates outward from resistively heated tissue.
