This study investigated the value of permanent atrial pacing as an adjunct to the current therapy in the chronic management of recurrent postoperative atrial reentrant tachycardia in patients with complex congenital heart disease. We studied the postpacing clinical course in 18 patients with recurrent atrial reentrant tachycardias unresponsive to conventional therapy who had an implanted atrial pacemaker. The pacemaker was programmed at a lower pacing rate 20% faster than the spontaneous mean daily rate previously determined with 24-hour Holter monitoring. Serial Holter recordings and pacemaker programming sessions were subsequently performed trying to mantain a paced atrial rhythm overdriving the spontaneous rhythm as long as possible. Twenty-four hour Holter monitoring documented a prevalent (> 80%) paced rhythm during the daily hours in all patients during the follow-up; all patients, however, required at least once a variation In programmed mode and pacing rate. Antiarrhythmic medications were discontinued after 6 months if the patient remained arrhythmia free while on pacing. Recurrences of atrial reentrant tachycardia occurred in five patients (29%) during the initial 6 months interval after the pacemaker implantation, while late recurrences occurred in only two patients (11 %). One patient died suddenly 10 months after the pacemaker implant. At the end of the follow-up, 15 patients (83%) were arrhythmia-free and only 2 of them were still on antiarrhythmic drugs. We conclude that permanent atrial overdrive pacing can be an important tool in the management of patients with atrial reentrant tachycardia following repair of congenital heart disease. 相似文献

Functional Anatomy of the Atria . The fact that some atrial and ventricular disorders (e.g., atrial fibrillation and heart failure) have a structural basis and cause atrial myocardial remodeling has led to increasing attention being paid to the atrial chambers. Furthermore, the rapid development of mapping and ablative procedures as a means of diagnosing and treating supraventricular arrhythmias has generated considerable interest in atrial gross anatomy, histology and ultrastructure. The aim of this article is to provide a comprehensive overview of the structure of the left and right atria (at macroscopic, histological and ultrastructural level) in relation to their function. In addition to analyzing normal atria, we also discuss functional anatomy in the case of atrial fibrillation and heart failure. (J Cardiovasc Electrophysiol, Vol. 22, pp. 223‐235, February 2011) 相似文献

A patient with ischemic dilated cardiomyopathy and history of ventricular fibrillation received an implantable Cardioverter defibrillator by the nonthoracotomy approach. Four years later, during elective replacement of an exhausted pulse generator, a superior vena caval thrombotic occlusion with collateral circulation through the azygos and emiazygos vein systems was documented. This occlusion occurred despite an anticoagulant treatment in the standard therapeutic range. We speculate that thrombotic occlusion might be secondary to a mechanical vessel injury. 相似文献

The acute and chronic electrophysiological effects on sinus function and AV nodal conduction of pentisomide (Pen), a new antiarrhythmic agent, were studied in ten patients with sick sinus syndrome (SSS) (group I) and in ten patients with normal sinus function (group II) using a permanent pacemaker with temporary pacing inhibition (Symbios 7005 Medtronic, Inc.). We measured noninvasively the corrected sinus node recovery time (CSNRT), the sino-atrial conduction time (SACT), according to Narula's method and the Wenckebach point before and after Pen administration, acutely and orally for 10 days. In group I intravenous injection (4 mg/kg) and oral administration (450 mg bid) of Pen significantly prolonged the CSNRT (+ 217% and + 149%, respectively) and the SACT (+ 63% and + 49%, respectively). In group II only the intravenous injection of Pen provoked a significant modification of CSNRT (+ 12%) and SACT (+ 14%). No modification in AV nodal conduction was noted in any patient. These results suggest that Pen must be used with caution in patients with sinus nodal dysfunction. 相似文献
