interrogation
The process of wirelessly communicating with an implanted cardiac device to retrieve stored data and assess function.
Full Definition
Device interrogation involves using an external programmer to establish communication with an implanted cardiac device through radiofrequency or inductive coupling. During interrogation, clinicians can retrieve stored diagnostic data, review therapy episodes, check lead function, assess battery status, and modify device programming. Modern devices store extensive data including arrhythmia episodes, pacing percentages, lead impedances, and patient activity levels. Regular interrogation is essential for ongoing patient management and device optimization.
Usage
Usage note: Context should clarify device interrogation vs. other medical uses of the term.
