Abstract
An implantable cardiac device comprises a device can and a single lead extending from the device can for cardiac emplacement. The lead senses a first cardiac wave propagating along a first vector and the same cardiac wave propagating along a second vector. The first vector may be between first and second locations on the lead, and the second vector between the lead and the device can or involving other locations on the lead so that a second lead is not needed and it is possible to make a single lead device.
Claims29
An implantable cardiac device comprising a device can and a single lead extending from said device can for cardiac emplacement, the lead configured to detect propagation of a cardiac wave along a first vector and propagation of said cardiac wave along a second vector, said first and second vectors having respectively different directions.
A method of measuring two non-parallel ECG vectors using an implanted cardiac device having a single lead placed within the heart, the method comprising:
- sensing propagation of a first cardiac wave along a first vector using said single lead;
- and
- sensing propagation of said first cardiac wave along a second vector using said single lead, said first vector and said second vector being respectively different vectors.
