Black Women's Recommendations for Developing Effective Type 2 Diabetes Programming.

The purpose of this study was to learn from 29 Black women how to develop effective Type 2 diabetes programming. Three focus groups were held in Des Moines, Iowa, during fall 2012. Results highlighted themes related to diabetes knowledge, diabetes management and prevention, physical activity, diet, and diabetes management programming.

Predictive value of clinical and electrophysiological variables in patients with chronic chagasic cardiomyopathy and nonsustained ventricular tachycardia.

Objective: Risk stratification of patients with nonsustained ventricular tachycardia (NSVT) and chronic chagasic cardiomyopathy (CCC).

Methods: Seventy eight patients with CCC and NSVT were consecutively and prospectively studied. All patients underwent to 24-hour Holter monitoring, radioisotopic ventriculography, left ventricular angiography, and electrophysiologic study.

Characteristics and identification of sites of chagasic ventricular tachycardia by endocardial mapping.

Objective: To study electrophysiological characteristics that enable the identification and ablation of sites of chagasic tachycardia.

Methods: Thirty-one patients with chronic Chagas' heart disease and sustained ventricular tachycardia (SVT) underwent electrophysiological study to map and ablate that arrhythmia. Fifteen patients had hemodynamically stable SVT reproducible by programmed ventricular stimulation, 9 men and 6 women with ages ranging from 37 to 67 years and ejection fraction varying from 0.

[Analysis of the junctional rhythm characteristics in patients with nodal reentry tachycardia treated with slow pathway radiofrequency ablation].

Purpose: To study the quantitative and qualitative aspects of junctional rhythm (JR) during radiofrequency (RF) catheter ablation of slow pathway in atrioventricular nodal reentrant tachycardia.

Methods: Twenty five patients, 5 males, ages ranging from 15 to 76 years, with recurrent atrioventricular nodal reentrant tachycardia, underwent to RF catheter ablation of slow pathway. During RF applications (40V, duration 60s) electrocardiographic was continuously recorded.

Medical treatment of cardiac arrhythmias in Chagas' heart disease.

There are no controlled clinical trials evaluating drug therapy in patients with ventricular arrhythmias and chronic chagasic cardiomyopathy. Empirical treatment with disopyramide (400-1, 1,000mg/d), phenytoin (4-6mg/d), mexiletine 600-1,200mg/d), propafenone (900mg/d), amiodarone (loading: 1,000mg/d, 10-14 days; maintenance 200-600mg/d), and sotalol (320mg/d) had efficacy and tolerance ranging from 18% to 90% with heterogeneous criteria for efficacy definition. Further studies with homogenous criteria are required to determine which is most appropriate drug therapy for patients with chronic chagasic cardiomyopathy and ventricular arrhythmias.

[Catheter ablation of ectopic incessant atrial tachycardia using radiofrequency. Reversion of tachycardiomyopathy].

A 8-year-old female patient with refractory incessant atrial tachycardia, very symptomatic and with left ventricular ejection fraction of 0.25. Electrophysiological study and endocardial mapping localized the site of the origin of atrial tachycardia in the superior right atrium.

[Catheter ablation of tachycardia of the outlet right ventricle using radiofrequency as power source].

Two female patients, 54 and 38 years-old with refractory ventricular tachycardia were undertaken to electrophysiologic study for diagnosis and radiofrequency ablation of their arrhythmias. The tachycardias were only inducible with intravenous isoproterenol infusion. The site of the origin of ventricular tachycardia was localized in the right ventricular outflow tract in both cases.
