摘要：
Implantable electromedical device or loop recorders or ILRs that solve the problem of very low arrhythmia detection specificities in, i.e., high number of false positives, based on detection and analysis of external noise, specifically muscle noise surrounding the electromedical device. Embodiments generally employ active detection of lead or device movement that induces signal artifacts indicative of external noise. One or more embodiments may detect lead or device movement through use of a piezoelectric transducer, for example located proximally to the device or in the lead of the electromedical.
