Title:
電極を備えた成形リード線
Document Type and Number:
Japanese Patent JP2005511165
Kind Code:
A
Abstract:
In general, an apparatus including a lead body and at least two electrodes. The lead body is so shaped that the lead body brings the first electrode against cardiac tissue yet keeps the second electrode away from contact with the cardiac tissue. These electrodes may be separated by a very small distance. When the lead is implanted in the superior vena cava, each electrode generates a distinct voltage signal as a function of sensed electrical activity. Although each electrode may sense a far-field R-wave in addition to a P-wave, the difference between the signals from the electrodes preserves the P-wave but includes a reduced far-field R-wave.
