Abstract: A dual chamber pacemaker system and method are provided for HOCM and like pacing therapy, with the feature of searching or scanning values of AV escape interval to define an optimized value at about the longest AV escape interval value consistent with full capture in response to a delivered ventricular pace pulse. In a preferred embodiment of the invention, the system and method sense and process FFRS signals derived from the atrial lead and otherwise, and obtain therefrom a characteristic which is evaluated for a determination of optimized AV escape interval. In one specific embodiment, the time durations between delivered ventricular pacing pulses and resulting FFRS signals are analyzed as a function of AV escape interval, and the optimized AV escape interval is chosen at about the longest AV escape interval corresponding to the longest such time duration, i.e., at about the knee of the FFRS time duration vs. AV escape internal curve. In another embodiment the FFRS  characteristic utilized is duration, and the system determines the longest AV  escape interval corresponding to the highest duration value. The system and method can be utilized either with an external programmer or can be adapted to operate automatically in an implanted pacemaker.

Title: Improvements relating to voice and data transmission
Inventor: MCALLISTER JAMES
IPC: H04J3/16
Filed: 1998-03-13
Abstract: Methods and apparatus for enabling simultaneous transmission of voice and data signals over a single subscriber line. Signals are time division multiplexed preferably using an ISDN access format such as the Basic Access or Primary Rate formats, but are treated separately at the exchange. Subscriber equipment combines signals from local computer and telephone devices for separation at corresponding exchange equipment. Similarly the exchange equipment combines signals from one or more packet networks and the public telephone network for separation at the subscriber equipment. Data signals are therefore passed by the exchange directly to or from a packet switched network while voice signals are passed directly to or from a telephone switched network. Channels available over the subscriber line are dynamically allocated with telephone signals generally taking preference over data signals.
