초록 ▼

During cross-chamber pacing, where anodal capture may not be desirable, pulses are applied between a cathode electrode in a first chamber and an anode electrode in a second chamber. A capture detector detects for capture of the second chamber by the pacing pulses. If capture of the second chamber persists, another electrode is selected as the anodal electrode. During single-chamber pacing, where anodal capture may be desirable, pulses are applied between a cathode electrode and an anode electrode associated with the same chamber. A capture detector detects for capture at both electrodes. If anodal capture is not detected, the energy of the pacing pulse is increased, until anodal capture is detected.

The device of claim 1 wherein the capture detector includes a threshold circuit having an automatically settable threshold. 13. An implantable cardiac stimulation device comprising: a first electrode that electrically couples to a first chamber of a heart;a second electrode that electrically couples to a second chamber of the heart;a pulse generator that provides pacing pulses between the first and second electrodes with the second electrode being an anodal electrode, wherein the pacing pulses are adapted to induce a depolarization and a mechanical contraction of the first chamber of the heart; anda capture detector adapted to detect capture of the second chamber by the pacing pulses using at least one second-chamber electrode. 14. The device of claim 13 wherein the at least one second-chamber electrode comprises the second electrode. 15. The device of claim 13 wherein the at least one second-chamber electrode comprises any electrode that electrically couples to the second chamber, other then the second electrode. 16. The device of claim 13 further comprising a case electrode and wherein the capture detector detects for capture of the second chamber by the pacing pulses using one second-chamber electrode and the case. 17. The device of claim 16 wherein the second-chamber electrode comprises the second electrode. 18. The device of claim 16 wherein the second-chamber electrode comprises any electrode that electrically couples to the second chamber, other then the second electrode.
