Detecting and diagnosing pacemaker malfunctions using a combined biopotential and pacing signal

摘要

A method (100, figure 4) of diagnosing a malfunction of a pacing system 30 includes the steps of receiving a combined signal (102, figure 4), detecting a pacing system malfunction (106, figure 4), detecting a cause of the malfunction (112, figure 4), and displaying the detected malfunction and detected cause of the malfunction (114, figure 4). The combined signal is a combination of heart biopotential signal 34 and pacer signals 36, and is detected using an electrode array 38. A malfunction detector 42 applies a malfunction logic to the combined signal to identify a pacing system fault and applies a morphology logic to the combined signal to identify a morphology of the signal. An output generator 44 receives an indication of the identified pacing system defect and the identified cause of the defect and creates an output 46 indicative of the identified pacing system malfunction and the identified cause.
