摘要： A method and apparatus are used to provide therapy to a patient experiencing ventricular dysfunction or heart failure. At least one electrode is located in a region associated with nervous tissue, such as nerve bundles T1-T4, in a patient's body. Electrical stimulation is applied to the at least one electrode to improve the cardiac efficiency of the patient's heart. One or more predetermined physiologic parameters of the patient are monitored, and the electrical stimulation is adjusted based on the one or more predetermined physiologic parameters.

摘要： Cardiac resynchronization therapy (CRT) delivered to a heart of a patient may be adjusted based on detection of a surrogate indication of the intrinsic atrioventricular conduction of the heart. In some examples, the surrogate indication is determined to be a sense event of the first depolarizing ventricle of the heart within a predetermined period of time following the delivery of a fusion pacing stimulus to the later depolarizing ventricle. In some examples, the CRT is switched from a fusion pacing configuration to a biventricular pacing configuration if the surrogate indication is not detected, and the CRT is maintained in a fusion pacing configuration if the surrogate indication is detected.

摘要： Techniques for adjusting pacing therapy based on ventriculo-atrial delay are described herein. These techniques may be used to control ventricular filling times during the delivery of pacing therapy. In some examples, a device or system delivers pre-excitation fusion pacing therapy to a ventricular chamber, determines a ventriculo-atrial delay interval for the ventricular chamber for at least one cardiac cycle, and adjusts the pacing therapy delivered by the implantable medical device to compensate for decreased ventricular filling time when the ventriculo-atrial delay interval is less than a threshold. In some examples, the device or system may adjust the pacing therapy by decreasing a pacing rate of the implantable medical device, increasing a pre-excitation interval for pacing of the ventricular chamber, and/or switching from a fusion pacing mode to a biventricular pacing mode.

摘要： A method of left ventricular pacing including automated adjustment of a atrio-ventricular (AV) pacing delay interval and intrinsic AV nodal conduction testing. It includes—upon expiration or reset of a programmable AV Evaluation Interval (AVEI)—performing the following: temporarily increasing a paced AV interval and a sensed AV interval and testing for adequate AV conduction and measuring an intrinsic atrio-ventricular (PR) interval for a right ventricular (RV) chamber. In the event that the AV conduction test reveals an AV conduction block condition then a pacing mode-switch to a bi-ventricular (Bi-V) pacing mode occurs and the magnitude of the AVEI is increased.

摘要： A preferred atrial-based pacing method and apparatus is provided using an intelligent cardiac pacing system to having the ability to continue atrial-based pacing as long as relatively reliable AV conduction is present. In the event that such relatively reliable AV conduction is not present, mode switching to a DDD/R or a DDI/R pacing mode while continually biased to mode switch back to atrial-based pacing. The standard or relatively reliable AV conduction may be changed either automatically or manually. This increases pacing that utilizes natural AV conduction however possible so as to gain all the benefits of cardiac contractile properties resulting therefrom, while tolerating the occasional missed ventricular depolarization (i.e., non-conducted P-wave). In the event where relatively reliable AV conduction is not present, the pacing mode is switched to a DDD/R mode while detecting a return of the relatively reliable AV conduction (and resulting mode switch to preferred atrial based pacing).
摘要翻译：只要存在相对可靠的AV传导，使用智能心脏起搏系统提供优选的基于心房的起搏方法和装置，以具有继续心房起搏的能力。在不存在这种相对可靠的AV传导的情况下，模式切换到DDD / R或DDI / R起搏模式，同时不断偏向模式切换回基于心房的起搏。标准或相对可靠的AV传导可以自动或手动改变。这增加了使用自然AV传导的起搏，尽可能地获得心脏收缩性质的所有益处，同时容忍偶尔的心室去极化（即，未传导的P波）。在不存在相对可靠的AV导通的情况下，起搏模式被切换到DDD / R模式，同时检测到相对可靠的AV导通的返回（并且导致的模式切换到优选的心房起搏）。

摘要： A hood for mounting over an outlet in a wall of a catch basin is disclosed. The hood includes a hood wall that forms a prow in a horizontal plane. The prow extends along an axis of the hood thereby achieving optimal flow conditions in the catch basin. In some embodiments the hood wall is shaped to be at least partially sealably mounted to the interior wall of a catch basin have a circular cross section in a horizontal plane. This novel hood shape facilitates installation of the hood in the circular catch basin, while also reducing the flow of oil and other pollutants into the outlet pipe in the circular catch basin. In some embodiments a perforated screed is also disclosed that surrounds the hood to aid in the capture of floatable pollutants.
