Although a sudden-onset criterion is available to differentiate sustained monomorphic ventricular tachycardias (SMVTs) and sinus tachycardias (STs), SMVTs arising during ST and SMVTs gradually accelerating above the cutoff rate can remain undetected. Regular paroxysmal atrial tachycardias (ATs) also can be undetected by onset and stability algorithms. We hypothesized that the first postpacing interval (FPPI) variability after overdrive right ventricular pacing may differentiate SMVTs from STs and ATs.\n          <\/jats:p>\n          <jats:p>\n            <jats:italic>Methods and Results<\/jats:italic>\n            \u2014FPPI variability was measured in 23 SMVTs (cycle length [CL] 366\u00b150 ms [VT group]), 27 supraventricular tachycardias, 15 episodes of induced or simulated ATs (CL 376\u00b129 ms [AT group]), and 12 exercise-related STs (CL 381\u00b124 [ST group]). Sequences of trains of 5, 10, and 15 beats were delivered with a CL 40 ms shorter than the tachycardia CL. An FPPI absolute mean difference between consecutive trains of 5 and 10 beats (\u0394FPPI) \u226425 ms identified all VTs (mean difference 5\u00b17 ms). In the AT group, the \u0394FPPI was &gt;25 ms in all sequences (mean difference 129\u00b160 ms,\n            <jats:italic>P<\/jats:italic>\n            &lt;0.01).
