摘要： 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. The device may also employ an automatic mode switch (AMS) threshold that is set higher than the ATAR threshold for use in switching from tracking modes to nontracking modes.

摘要： A method and apparatus for analyzing cardiac information involves recording both atrial and ventricular information related to a recognized event. This information can then be transmitted by telemetry to the physician and graphed on a common graph which plots both atrial and ventricular information over the time period of the event. This technique allows greater ability to discern the true nature of these events, including whether a given event is a sinus tachycardia due to exercise or a ventricular tachycardia which might necessitate treatment. Therefore, the present invention enables more accurate analysis of cardiac information and thereby makes possible the more appropriate application of treatment.

摘要： Methods and systems are provided for discriminating heart arrhythmias. The methods and systems include identifying an arrhythmia, recording a predetermined number of beats during the arrhythmia as a base arrhythmia (BA) beats; delivering anti-tachy pacing (ATP) therapy to at least one chamber of the heart. After delivering the ATP therapy, the methods and system record at least one return beat representing cardiac activity following the ATP therapy, determines whether the return beat originated in a reference chamber of the heart, compares a morphology of the return beat to a morphology of the BA beat; and declares a VT or SVT based on the comparing operation.

摘要： Techniques are described for generating diagnostic information to aid in determining whether cardiac ischemia within a patient is clinically actionable. In one example, a pacemaker or implantable cardioverter/defibrillator (ICD) detects information pertaining to arrhythmia precursors and to episodes of sustained arrhythmias, as well as information pertaining to episodes of cardiac ischemia. The implanted device then correlates the arrhythmia precursors and the sustained arrhythmias with the episodes of cardiac ischemia so as to generate diagnostics permitting a physician reviewing the diagnostics to determine whether the ischemia is clinically actionable. In some implementations, the diagnostics are instead generated by an external system based on raw data provided by the implanted device. In some implementations, the device itself determines whether the ischemia is clinically actionable and automatically controls therapy or generates warning signals accordingly.

摘要： Systems and methods are provided for use by implantable medical devices equipped to deliver multi-site left ventricular (MSLV) pacing. Sequential 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, 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. The device may also employ an automatic mode switch (AMS) threshold set higher than the ATAR threshold for use in switching from tracking modes to nontracking modes.

摘要： Post-exercise arrhythmias are detected by an implantable medical device. In some aspects, post-exercise arrhythmia may be prognostic of a worsening cardiovascular condition. Thus, the detection of post-exercise arrhythmia may be used as an indicator for adjusting the therapy prescribed for a patient. In some aspects post-exercise arrhythmia are detected if a patient is exercising at a level that equals or exceeds a threshold exercise level. In some aspects, therapy for a patient is modified if the detected post-exercise arrhythmia exceeds a threshold arrhythmia level. In some aspects therapy for a patient is modified if ischemia is detected in conjunction with post-exercise arrhythmia.
