Abstract: The purpose of this study was to determine the termination and acceleration rates for 1 to 6 attempts of antitachycardia pacing [ATP] delivered by ICD in order to terminate spontaneously occurring VTs. Twenty-four ICD recipients with active ATP programs, including a maximum of six ATP sequences and spontaneously occurring VTs during follow-up, were investigated. During a mean follow-up of 42 +/- 15 months (range, 17-63 months) 413 spontaneous VT episodes (17 +/- 14; range, 1-49 per patient) resulting in approp… Show more

“…In the remaining 14/71 monolayers (a relatively low incidence as found for antitachycardia pacing by ICDs [2,3]), the transiently formed wave tips (i.e. transiently increased PS#) evolved after pacing into 2-5 stable reentrant waves (a multi-wave reentry) which activated cells at a rate 10 -70% faster than the rate of the preceding single loop reentry.…”

“…After functional reentry was induced and equilibrated for 5 -10 min, rapid point pacing trains (pulse amplitude < 1.4Â threshold to avoid cell damage, pulse duration = 10 ms) were applied from one of four peripheral sites (3, 6, 9 or 12 o'clock positions) in an attempt to stably perturb (terminate, accelerate, or decelerate) the reentry. To create different situations present during antitachycardia pacing by ICDs [1][2][3], pacing was applied relatively far (at least 7 mm) from the reentry core, and the onset time relative to local activation by reentry, the length (3 -25 pulses), and the rate (1.1 -1.5Â reentry rate) of the pacing train were arbitrarily varied. If reentry was terminated in one of the attempts, rapid pacing was reapplied at the center of the monolayer to induce another functional reentry, and the pacing protocol to perturb the reentry was repeated.…”

“…Predictors of success were VT rates <180 bpm and ATP at 91% of the basic cycle length. A retrospective analysis assessed the success rate of one to six burst sequences (eight‐beat train at 81% of the basic length) in a VT zone programmed from 140 to 220 bpm 55 . The first ATP interrupted 59% of terminated VTs and 97% were cardioverted by the fourth sequences.…”
