Patent ID: 8374692

Claim:
A method comprising: monitoring a parameter indicative of impedance of a lead, wherein monitoring the parameter indicative of impedance of the lead comprises monitoring at least one of a frequency or a phase of a signal indicative of impedance of the lead; monitoring a parameter indicative of motion of the lead, wherein monitoring the parameter indicative of motion of the lead comprises monitoring at least one of a frequency or a phase of a signal indicative of motion of the lead; identifying a correlation between the parameter indicative of impedance of a lead and the parameter indicative of motion of the lead by at least one of: determining that the frequency of the signal indicative of impedance of the lead and the frequency of the signal indicative of motion of the lead are substantially the same, or determining that the signal indicative of impedance of the lead and the signal indicative of motion of the lead are in phase; and identifying a lead related condition based on the correlation.
