Abstract
A process and a device for regulating the stimulation frequency of heart pacemakers are disclosed. The process comprises generating with the aid of light emitted by a light-emitting element, reflected by the blood of a patient, and received by a light-receiving element, a current flow which causes, in a measuring probe, an increasing of the current flow at a constant probe voltage or a damping of the probe voltage at constant current flow. Thereafter, one of the possible changing values is measured and the change, with time, is evaluated as a measured quantity proportional to the change, with time, of the blood oxygen saturation, and, as a function of the measured quantity, the stimulation frequency of the heart pacemaker is regulated in such a manner that the greatest possible blood oxygen saturation is always achieved with the lowest stimulation frequency. The device for practicing the invention comprises a measuring probe containing at least one combination of only two active optoelectronic elements, one light-emitting element and one light-receiving element; a control circuit electrically connected to the measuring probe; a stimulation catheter in which the measuring probe is incorporated, and at least two electric lines leading through the stimulation catheter and electrically connecting the measuring probe to the control circuit of the measuring probe.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
