Cryosurgical treatment of atrioventricular node reentrant tachycardia.
Paroxysmal supraventricular tachycardia most commonly arises from reentry within the atrioventricular (AV) node. Although ablation of the His bundle has gained popularity for treating patients with AV node reentrant tachycardia refractory to medical therapy, undesirable sequelae include complete heart block and the necessity for a permanent pacemaker. To obviate this limitation, we have develop...
متن کاملTermination of sustained ventricular tachycardia by ultrarapid subthreshold stimulation in humans.
Our purpose was to investigate the efficacy, safety, and electrophysiological mechanism of ultrarapid subthreshold electrical stimulation in terminating sustained ventricular tachycardia (VT) in humans. Fifteen patients with inducible sustained hemodynamically stable VT and whose VT cycle length ranged between 295 and 440 msec (337 +/- 60 msec) were included in this study. The stimulation thres...
متن کاملEntrainment for Distinguishing Atypical Atrioventricular Node Reentrant Tachycardia From Atrioventricular Reentrant Tachycardia Over Septal Accessory Pathways With Long-RP Tachycardia
Background—The response to right ventricular (RV) entrainment is useful to distinguish atypical AV node reentrant tachycardia from AV reentrant tachycardia using a septal accessory pathway. Whether entrainment can differentiate between AV node reentrant tachycardia and AV reentrant tachycardia in patients with long-RP tachycardia has not been systematically validated. Methods and Results—Twenty...
متن کاملFast pathway ablation for atrioventricular node reentrant tachycardia.
The pioneering surgical reports of Ross et al. (1) and Cox et al. (2) set the stage for catheter ablation of atrioventricular (AV) node reentrant tachycardia by demonstrating that this type of tachycardia could be cured without damage to the compact AV node or impairment of AV conduction. Several experimental and clinical studies (3-8) have indicated that the anterior and posterior inputs into ...
متن کاملEntrainment from the para-Hisian region for differentiating atrioventricular node reentrant tachycardia from orthodromic atrioventricular reentrant tachycardia.
AIMS The difference between the stimulus-atrial and ventriculo-atrial intervals (SA-VA) and between the post-pacing interval and the tachycardia cycle length (PPI-TCL) during entrainment from the right ventricular apex distinguishes atrioventricular node reentrant (AVNRT) from orthodromic atrioventricular reentrant tachycardia (AVRT). We hypothesized that these features still apply when entrain...
