| 摘要 | An apparatus and method is provided that determines a connection quality of an electrode to a patient. A current source is connected to a first electrode and a switch is connected to a second electrode for selectively connecting the second electrode to ground. A processor is connected to the first electrode and a third electrode and the processor detects a voltage difference between the first electrode and the third electrode upon application of a current to the first electrode by the current source to determine connection quality data for the first electrode. | ||

| 主权项 | 1. An apparatus that determines a connection quality of an electrode to a patient, the apparatus comprising: a current source connected to a first electrode; a switch connected to a second electrode for selectively connecting the second electrode to ground; and a processor connected to the first electrode and a third electrode, said processor detecting a voltage difference between the first electrode and the third electrode upon application of a current to the first electrode by said current source to determine connection quality data for the first electrode, wherein said apparatus is connected to electrodes of an ECG monitor and said processor disables a drive electrode of the ECG monitor prior to measuring connection quality data. | ||
