Background: Dofetilide is a class III antiarrhythmic drug indicated for the conversion and maintenance of normal sinus rhythm in symptomatic patients with atrial fibrillation/atrial flutter. Delay in initiation of dofetilide therapy may increase the duration of hospitalization from two nights to three nights to complete US Food and Drug Administration-required monitoring. Therefore, substantial cost savings may be associated with implementation of an institution-specific dofetilide initiation protocol in order to reduce hospitalization to two nights.

We assessed the effects of cognitive behavioral stress management (CBSM) on mood state and potentially arrhythmogenic cardiovascular responses to mental stress in ICD patients, in support of further larger scale arrhythmia trials.
Methods: A total of 103 ICD recipients were randomly assigned to 10-week programs of CBSM or "Patient Education" (ED).

Background: The purpose of this study was to measure the extent of left atrial-pulmonary vein (LA-PV) connections and determine the relation to PV firing in patients with atrial fibrillation (AF).
Methods And Results: Ten close-bipolar (1 mm-spacing) Lasso electrograms were recorded circumferentially around 210 PVs (excluding 2 right middle PVs and 4 left common trunks) in 62 patients with AF. PV firing was provoked by isoproterenol (4 microg/min) and cardioversion of pacing-induced AF.
