Inducibility Testing
Systematic pacing protocols used to provoke arrhythmias during electrophysiology study for diagnostic or therapeutic assessment.
Full Definition
Inducibility testing involves standardized programmed stimulation protocols designed to initiate sustained arrhythmias in the controlled environment of the electrophysiology laboratory. These protocols typically include single, double, and triple premature stimuli delivered from multiple sites at various cycle lengths and coupling intervals. Inducibility testing is fundamental for diagnosing the substrate for sustained arrhythmias, assessing the efficacy of antiarrhythmic interventions, and guiding ablation strategies. The reproducible induction of clinical arrhythmias confirms their mechanism and allows for detailed mapping and treatment. Standardized protocols ensure consistency across different centers and operators.
Usage
Usage note: Use 'inducibility' as noun form, 'inducible' as adjective. Avoid 'induction testing' as alternative.
