Noninvasive electrocardiography monitoring for very early recurrence predicts long-term outcome in patients after atrial fibrillation ablation.

Background: Atrial fibrillation (AF) is the most common sustained arrhythmia, and catheter ablation has been shown to be a highly effective treatment for patients with symptomatic AF. Very early recurrence (VER) of AF within 7 days after catheter ablation is common, but the clinical significance of VER remains unclear. We have examined the usefulness of the noninvasive electrocardiography monitor for the detection of VER and the relationship between VER and late recurrence (LR).

[Causes of insufficient anticoagulation in Chinese patients with non-valvlar atrial fibrillation].

Objective: To evaluate the factors responsible for the insufficient application of oral anticoagulation (OAC) in Chinese patients with non-valvular atrial fibrillation.

Methods: The research is a single center registration study in a tertiary referral hospital in Beijing. The general characteristics, history of atrial fibrillation, comorbidities and anticoagulation treatment were obtained from all patients.

[Clinical analysis of 120 cases of infective endocarditis].

Objective: To improve the diagnosis and treatment of infective endocarditis (IE) by exploring its causes, pathogenic microorganism and clinical characteristics.

Methods: The clinical data of 120 IE patients treated in Peking Union Medical College Hospital from October 1997 to September 2007 were analyzed retrospectively.

Results: Of the 120 consecutive cases diagnosed as IE according to the Duke's new criteria, 79 were male and 41 female with a average age of (43.
