Is antero-posterior position superior to antero-lateral position for placement of electrodes for external cardioversion of atrial fibrillation?

Anterior-posterior versus anterior-lateral electrode positions for external cardioversion of atrial fibrillation: a randomised trial.

BACKGROUND External cardioversion is a readily available treatment for persistent atrial fibrillation. Although anatomical and electrophysiological considerations suggest that an anterior-posterior electrode position should create a more homogeneous shock-field gradient throughout the atria than an anterior-lateral position, both electrode positions are equally recommended for external cardiove...

External cardioversion of atrial fibrillation: role of paddle position on technical efficacy and energy requirements.

AIM To define the effect of defibrillator paddle position on technical success and dc shock energy requirements of external cardioversion of atrial fibrillation. METHODS 301 patients (mean (SD) age 62 (11) years) with stable atrial fibrillation were randomly assigned to elective external cardioversion using anterolateral paddle position (ventricular apex-right infraclavicular area; group AL (...

Results of Antero-lateral Cordotomy for Pain in Cancer.

Initial energy for external electrical cardioversion of atrial fibrillation.

OBJECTIVE To investigate the initial energy level required for electrical cardioversion of atrial fibrillation (AF). METHODS We studied patients undergoing electrical cardioversion in the 1st Multicenter Trial of SOCESP. Patients were divided into 2 groups according to the initial energy level of electrical cardioversion: 100J and >/=150J. We compared the efficacy of the initial and final sho...

Effects of active and passive lacebacks on antero-posterior position of maxillary first molars and central incisors.

The purpose of this study was to compare the effects of active and passive lacebacks on antero-posterior position of maxillary first molars and central incisors during leveling phase. Twenty-three subjects with Class I and Class II malocclusion were treated with first premolars extraction using preadjusted appliances (MBT 0.022-inch brackets). The leveling phase was performed with stainless ste...
