Abstract: In some embodiments, an implantable medical device (IMD) system may include one or more of the following elements: (a) an oxygen sensor for measuring oxygen extraction from blood flowing through a coronary sinus of a patient's heart, (b) an oxygen signal generated by the oxygen sensor, (c) an IMD coupled to the oxygen sensor, wherein the IMD is configured to output pacing pulses as a function of the oxygen signal, and (d) an atrial and a ventricular pacing lead coupled to the IMD to deliver the pacing pulses to the patient's heart, wherein the IMD generates the pacing pulses as a function of the oxygen signal, wherein the pacing pulses are adjusted by the IMD as a function of the oxygen signal, wherein the IMD is configured to adjust the pacing pulses to increase oxygen in the blood flow through the coronary sinus.

Abstract: The invention relates to a process and a device for the removal of dust, HF, HCl, SO2, SO3, heavy metals, heavy-metal compounds, polyhalogenated hydrocarbons and polycyclic hydrocarbons from combustion flue gases by treating the pollutant-containing combustion flue gases with a sorbent in a circulating fluidized bed. The process is characterized in that the sorbent used is a mixture of Ca(OH)2, at least one naturally occurring zeolite and a carbon-containing substance, in that the treatment of the pollutant-containing combustion flue gases with the sorbent is carried out at from 120 to 180° C.

Abstract: Delivery of fusion pacing therapy to a later depolarizing ventricle (V2) of a heart of a patient may be timed based on the depolarization of the V2 during at least one prior cardiac cycle. In some examples, a V2 pacing pulse is delivered upon the expiration of a pacing interval that begins at detection of an atrial sense or pace event (AP/S). The pacing interval may be substantially equal to the duration of time between an AP/S and a V2 sensing event of at least one prior cardiac cycle decremented by an adjusted pre-excitation interval (PEI). In another example, the V2 pacing pulse is delivered at the expiration of a pacing interval that begins upon detection of a V2 sensing event of a prior cardiac cycle. The pacing interval may be substantially equal to a duration of time at least two subsequent V2 sensing events decremented by the adjusted PEI.

Abstract: An implantable medical device and associated method control the delivery of extra systolic stimulation by determining a coupling interval, setting an extra systolic interval in response to the coupling interval; and delivering a supraventricular stimulation pulse upon expiration of the extra systolic interval. The supraventricular stimulation pulse evokes a depolarization that is conducted to the ventricles occurring at a ventricular coupling interval relative to a ventricular event.

Abstract: A method, apparatus, or system to identify optimal parameters for programming a cardiac stimulator by a matrix-based decision algorithm using sensor data representing cardiovascular function. The parameters include pacing intervals optimized concurrently to produce the maximum resulting cardiac function.

Abstract: A cardiac rhythm sensor positioned on or close to the heart senses electrical or mechanical activity and transmits a cardiac rhythm signal wirelessly to a subcutaneous ICD. Arrhythmia detection and delivery of therapy are performed by the SubQ ICD based upon the cardiac rhythm signal received from the sensor.
