percutaneous repositioning of dislodged atrial pacing lead
the overall rate of atrial pacing lead dislodgement is estimated to be about 3%. these leads are generally repositioned via a second operation through opening the pacemaker pocket. some operators have introduced percutaneous techniques using snare system or deflectable catheters for this purpose. in this article we present our experience with five cases of percutaneous lead repositioning. three...
متن کاملEffects of postshock atrial pacing on atrial defibrillation outcome in the isolated sheep heart.
BACKGROUND Failed atrial defibrillation shocks are associated with organization of postshock activity and a substantial postshock electrical quiescence. We investigated the ability of a train of pacing stimuli to capture or locally entrain atrial myocardium during the quiescent period after low-energy shocks and to alter defibrillation outcome. METHODS AND RESULTS High-resolution video imagin...
متن کاملAtrial and Ventricular Pacing
The role of simultaneous and sequential atrioventricular (AV) stimulation in prevention of tachyeardia induction, and the underlying electrophysiologic mechanisms involved, were studied in 10 patients with documented paroxysmal reentrant supraventricular tachycardia (PSVT). Reentry circuit was localized to the AV node in seven of 10. The remaining three cases had Wolff-Parkinson-White (WPW) syn...
متن کاملSuppression of atrial fibrillation by atrial pacing.
BACKGROUND Atrial fibrillation (AF) is a common arrhythmia in patients with an implanted pacemaker, but the role of atrial pacing in preventing AF is still unclear. METHODS AND RESULTS Sixty-six patients (67.8+/-12.1 years) were enrolled: 54 with sick sinus syndrome (SSS), 11 with atrioventricular blocks (AVB), and 1 with SSS and AVB. The prevalence of AF was investigated. In 22 patients with...
متن کاملLong-term pervenous atrial pacing.
Long-term pervenous right atrial pacing has been used in five patients with intact atrioventricular (A-V) conduction for the treatment of refractory ventricular arrhythmias in two subjects and marked sinus bradyeardia in three, two of whom also had paroxysmal supraventricular arrhythmias. The pervenous method was used to avoid a thoracotomy, and atrial pacing was chosen over ventricular pacing ...
