Publication number: 20140309538Abstract: An apparatus and method for detecting phrenic nerve stimulation (PNS) including computing a power spectral density (PSD) of spatial data of a sensor; determining two spectral magnitudes from the PSD; computing a ratio of the two spectral magnitudes; and comparing the ratio to a threshold to detect PNS. In one example, detecting PNS includes computing a PSD of spatial data of an externally placed sensor; determining a diaphragmatic spectral magnitude and a respiratory motion spectral magnitude from the PSD; and computing a ratio of the diaphragmatic spectral magnitude to the respiratory motion spectral magnitude to detect PNS. In one example, detecting PNS includes computing an oscillation amplitude of spatial data of a sensor; computing a baseline wander amplitude of the spatial data of the sensor; computing a ratio of the oscillation amplitude to the baseline wander amplitude; and comparing the ratio to a threshold to detect PNS.Type: ApplicationFiled: April 10, 2013Publication date: October 16, 2014Applicant: PACESETTER, INC.Inventors: Rohan A.

Patent number: 8447400Abstract: Systems and methods are provided for use by implantable medical devices equipped to deliver multi-site left ventricular (MSLV) pacing. MSLV is associated with a relatively long post-ventricular atrial blanking (PVAB) period that might limit the detection of pathologic rapid organized atrial tachycardias (OAT). In one example, MSLV cardiac resynchronization therapy (CRT) pacing is delivered within a tracking mode. A possible atrial tachycardia is detected based on the atrial rate exceeding an atrial tachycardia assessment rate (ATAR) threshold. The device then switches to single-site LV pacing, thereby effectively shortening the PVAB to detect additional atrial events that might otherwise be obscured, and thereby permitting the device to more reliably distinguish organized atrial tachycardias (such as atrial flutter) from sinus tachycardia.Type: GrantFiled: June 24, 2010Date of Patent: May 21, 2013Assignee: Pacesetter, Inc.Inventors: Rohan A.

In one example, sequential MSLV cardiac resynchronization therapy (CRT) pacing is delivered within a tracking mode. A possible atrial tachycardia is detected based on the atrial rate exceeding an atrial tachycardia assessment rate (ATAR) threshold. The device then switches to either single-site LV pacing or simultaneous MSLV pacing, thereby effectively shortening the PVAB to detect additional atrial events that might otherwise be obscured, and thereby permitting the device to more reliably distinguish OATs (such as atrial flutter) from sinus tachycardia.Type: GrantFiled: May 16, 2011Date of Patent: December 11, 2012Assignee: Pacesetter, Inc.Inventors: Derrick W.
