摘要： A system and method for controlling cardiac ventricular tachyarrhythmias by acquiring a pressure signal representative of coronary venous pressure (CVP) from a pressure sensor implanted within a coronary vein of the patient. A CVP index is derived based on the pressure signal. The onset of a ventricular tachyarrhythmia episode is detected based on a cardiac rates signal. The CVP index and the rate signal are monitored and, responsive to the rate signal indicating a sustained tachycardia episode during the episode monitoring period, anti-tachycardia therapy selectively withheld and the episode monitoring period is extended based on the CVP index.

摘要： A system and method for estimating a hemodynamic performance parameter value of a patient's heart. The system includes a pulse generator and a medical electrical lead implanted partially within a coronary vein of the heart. The lead includes at least one sensor located within the coronary vein configured to generate a signal indicative of at least one dimensional parameter of the coronary vein. Changes in the dimensional parameter during one or more cardiac cycles are measured. The hemodynamic performance parameter is estimated based on the change in the dimensional parameter of the coronary vein.

摘要： Methods, systems, and computer program products are provided for measuring effectiveness of content items included in a campaign. One example method includes providing a corpus of campaigns, where a campaign defines parameters for presentation that specify circumstances under which content items are presented to users in response to requests. The corpus is filtered by identifying one or more candidate campaigns, where each of the identified candidate campaigns is associated with a geographic region and includes one or more constraints that permit pausing distribution of content items without compromising campaign goals. For each candidate campaign, one or more experimental geographic locations included in the geographic region are determined that are substantially representative of the region. Presentation of at least one of the content items is paused for a time period, and content item effectiveness is measured by comparing resource conversions for experimental and control geographic locations.

摘要： A deflectable catheter assembly is disclosed. The assembly comprises a catheter shaft having a catheter proximal section and a catheter distal section, and at least one lumen extending therethrough. The catheter distal section is more flexible than the catheter proximal section. A tendon is disposed within a first lumen of said catheter shaft. The first lumen is approximately centrally located within the catheter shaft at the catheter proximal section. The first lumen is located off-center of the catheter shaft at the catheter distal section. The tendon is able to deflect the catheter distal section when being pulled on. A catheter handle is coupled to the catheter shaft at the catheter proximal section, the catheter handle includes a control mechanism to control the tendon.
