ATLANTA -- A lenient heart rate target of less than 110 bpm at rest in patients with permanent atrial fibrillation is as effective in preventing cardiovascular morbidity and mortality as is the tight rate control strategy recommended in current guidelines, and far more convenient both for patients and physicians, according to a new study.
The strict rate control strategy--which is not evidence based--assumes that a lower heart rate target will result in fewer symptoms and cardiovascular events.
Mortality with atrial fibrillation is similar with rhythm control and rate control treatment.
The large multicenter CABANA trial, which is now recruiting, may be the last and best chance to learn if maintaining sinus rhythm confers a survival advantage over rate control in patients with atrial fibrillation.

SELECTION CRITERIA * We included English-language articles describing randomized controlled trials of drags used for heart rate control in adults with atrial fibrillation.
An all-new all-wheel drive system with yaw rate control is also available.
Sanofi-Aventis has applied to the Food and Drug Administration and to European authorities for marketing approval for dronedarone for maintenance of sinus rhythm and ventricular rate control in those patients with atrial fibrillation or flutter.
The potential reduction in morbidity and mortality noted with dronedarone in EURIDIS/ADONIS, coupled with new evidence presented at the AHA meeting to the effect that the drug is effective not only for rhythm control but for rate control as well, suggests dronedarone may provide an important new treatment approach in atrial fibrillation, according to Dr.
Its architecture leverages open source spam and virus solutions in conjunction with twelve defense layers: denial of service and security protection, IP block list, rate control, dual layers of virus protection, user specified rules, spam fingerprint check, Intent Analysis, spam rule-based scoring, image analysis, sender authentication, recipient verification and Bayesian analysis.
Over time, the most effective approach to pharmacologic rate control in patients with atrial fibrillation is a [beta]-blocker in combination with digoxin, Brian Olshansky, M.
