Background
| Age, Gender | 68, Male | | Heart Disease | None documented | | Ejection Fraction | 40% | | Clinical Arrhythmia | Near-syncopal paroxysmal atrial tachycardia (weekly) | | Previous Therapy | Refractory to drug treatment | | Treadmill Results | Non-sustained runs of atrial tachycardia (cycle length = 410 ms) and atrial extrasystoles that were readily and repeatedly induced | | Conventional EP Study | Unsuccessful, due to non-sustained runs | 12 Lead
EnSite 3000® Display
Inductions: Atrial extrasystoles were recorded during the study, some spontaneous, some induced. No sustained runs were induced, but the extrasystoles matched those recorded on the earlier 12-lead. Mapping: A single, early site was consistently observed near the superior lateral right-atrial wall, near the mapped location of the sinus node. <*dv_2*>Ablation: Four RF lesions were on and near the early activation site. The EnGuide™ locator signal was used to position the ablation catheter at the target site, avoiding the SA node. After the ablation, no spontaneous or induced atrial extrasystoles were observed. Case outcome: The patient has been arrhythmia-free since the EnSite 3000® procedure. | |
