Patent FR-2533817-A1 (FR)
Title: Internal ECG detector using angled dual electrode
Inventor: GOLDREYER BRUCE NEIL
IPC: A61B5/296
Filed: 1983-08-04
Abstract: The traces obtained from inside the chambers of the heart by this method have such clearly defined P, QRS, and T waves that it can be used to synchronise an artificial pacemaker. The normal ECG trace from the body surface has a well-defined P-wave, QRS complex and T-wave. However, the normal traces from conventional electrodes placed within the heart have insufficient differentiation between the P-wave and the QRS-complex if the electrode is in the auricle; and between the QRS complex and T-wave reactions, if in the ventricle. By using the angled dual electrode placed in the auricle, a trace can be obtained which has a single P-wave pulse. If placed in the ventricle, the trace has a clear QRS- complex and a negligible T-wave reaction.
