Abstract

Electrophysiologic studies were performed in 172 consecutive patients for evaluation of documented sustained ventricular tachyarrhythmias. One hundred thirteen patients presented with sustained ventricular tachycardia that was hemodynamically stable, and 59 patients presented with cardiac arrest. Seventy-one patients without previously documented or suspected ventricular arrhythmias were also studied to determine the specificity of our electrophysiologic study protocol. The stimulation protocol included single, double, and triple right ventricular extrastimuli and rapid ventricular pacing at multiple cycle lengths performed at one or more right ventricular sites. Stimulation was performed at one or more left ventricular sites in patients with documented spontaneous arrhythmias when right ventricular programmed stimulation failed to induce sustained ventricular tachycardia. Ventricular tachyarrhythmias were induced in 110 (97%) of the patients who presented with sustained ventricular tachycardia, in 48 (81%) of the patients who presented with cardiac arrest, and in 28 (40%) of the patients without documented spontaneous arrhythmias. Right ventricular triple extrastimuli induced tachycardia in 22% of patients who presented with sustained ventricular tachycardia vs 46% of those who presented with cardiac arrest (p less than .001). Left ventricular stimulation was required for tachycardia induction in 3% of patients with stable tachycardia vs 19% of those with cardiac arrest (p less than .01). Triple extrastimuli induced 57% of tachycardias in the 28 patients without spontaneous arrhythmias, and virtually all of these tachycardias were polymorphic and nonsustained. The cycle lengths of tachycardias induced in each group by double and triple extrastimuli were similar, but the tachycardias induced in patients with cardiac arrest were significantly faster than those induced in the ventricular tachycardia group (mean cycle length 218 vs 291 msec, p less than .001).(ABSTRACT TRUNCATED AT 250 WORDS)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
