MODIFICATION OF PACEMAKER TACHY RESPONSE BASED ON FFRW SENSING

摘要

A pacemaker control method and apparatus for determining the presence ofatrial tachyarrhythmias uses a true interval value andcompares it to a predetermined tachy value. The true interval value is updatedbased on the presence of far field R waves in PVARP thatmeet certain sequencing criteria. The criteria selected allows the controlmethod and apparatus to reduce or eliminate event sequences thatwill generate false positive tachy detection and subsequent mode switching,while still allowing for the detection of tachy events in PVARP.
