20090253974 | Use of tools, mapping systems, catheters, electrodes or any devices targeting any autonomic nerve(s) structure(s) in the human heart for the diagnostic, treatment and/or prevention of the recurrence of cardiac arrhythmias. - Treatment of atrial fibrillation, targeting the triggering autonomic nerve structures have been shown high efficacy for converting to a sinus rhythm state. However, the efficacy is limited to a short time (<3 months) with a high degree of recurrence of atrial arrhythmias.

A vehicle seat includes sheet-shaped sensors attached to a seat back, and can measure the heart rate of a seated passenger based on vital signals of the seated passenger detected by the sheet-shaped sensors. At each sheet-shaped sensor, a sensor overlap reduction section is provided to reduce partial overlapping of the sheet-shaped sensor when the seated passenger leans on the seat back. Specifically, each sheet-shaped sensor includes a first cutout extending toward the center of the sheet-shaped sensor at an outer peripheral portion of the sheet-shaped sensor, and a second cutout formed continuously from the first cutout and extending opposite to the center along the outer peripheral portion of the sheet-shaped sensor. | 03-31-2016 |
