Patent Issued for Use of Periodicity in Medical Data Analysis

September 8, 2014

By a News Reporter-Staff News Editor at Cardiovascular Week -- From Alexandria, Virginia, NewsRx journalists report that a patent by the inventors Schatz, Kelly (Navarre, FL); Sweeney, Robert J. (Woodbury, MN), filed on April 2, 2012, was published online on August 26, 2014 (see also Cardiac Pacemakers, Inc.).

The patent's assignee for patent number 8818495 is Cardiac Pacemakers, Inc. (St. Paul, MN).

News editors obtained the following quote from the background information supplied by the inventors: "Cardiac rhythm management devices are implantable devices that provide electrical stimulation to selected chambers of the heart in order to treat disorders of cardiac rhythm. A pacemaker, for example, is a cardiac rhythm management device that paces the heart with timed pacing pulses. The most common condition for which pacemakers have been used is in the treatment of bradycardia, where the ventricular rate is too slow. If functioning properly, the pacemaker makes up for the heart's inability to pace itself at an appropriate rhythm in order to meet metabolic demand by enforcing a minimum heart rate and/or artificially restoring AV conduction. Implantable devices may also be configured to treat tachyarrhythmias such as fibrillation with electrical stimulation.

"As a part of performing their functions in delivering therapy, implantable cardiac devices may equipped with various sensing modalities for detecting cardiac electrical activity as well as measuring other physiological parameters. Other types of implantable devices may be configured for delivering other types of therapy and/or only monitoring particular physiological parameters. A patient management system may be constructed of an implantable device configured with a telemetry system for communicating such collected data to an external device and ultimately to clinical personnel for evaluation."

As a supplement to the background information on this patent, NewsRx correspondents also obtained the inventors' summary information for this patent: "A patient management system is described that includes an implantable device for collecting one or more physiological parameter values and associated timestamps indicating the time at which the value is collected. The system is then configured to determine the periodic variation, if any, of a particular physiological parameter and use that periodicity in assessing changes in the parameter values over time."
