Filter by:There is an important need to maintain clinical skills, provide quality training and expertise, and provide an environment that stimulates ideas for clinical research. This study permits inpatient evaluation and management of patients with heart disease who do not qualify to participate in studies currently being conducted by the Cardiology Branch of the National Heart, Lung, and Blood Institute.
To compare conventional treatment of congestive heart failure (CHF) with two experimental interventions: amiodarone and an implantable cardioverter-defibrillator (ICD).
To determine if dual chamber rate-modulated pacing (DDDR) in patients with sick sinus syndrome is superior to single chamber pacing (VVIR) with respect to subsequent frequency of adverse clinical events such as stroke, quality of life and function, and cost effectiveness.
To compare two standard treatment strategies for atrial fibrillation: ventricular rate control and anticoagulation vs. rhythm control and anticoagulation.
To test the hypothesis that implantable cardioverter defibrillator (ICD) therapy will improve survival in coronary heart disease patients at high risk of death, especially arrhythmic death.
To evaluate if use of an implantable cardiac defibrillator (ICD) results in reduction in total mortality, when compared with conventional pharmacological therapy, in patients resuscitated from sudden cardiac death who are otherwise at very high risk of mortality from arrhythmic causes.
To determine whether electrophysiologic study (EPS) or Holter monitoring (HM) was the better method for selecting effective long-term antiarrhythmic drug therapy in patients with sustained ventricular tachycardia, ventricular fibrillation, or an episode of aborted sudden death.
To determine the benefits and risks of oral anticoagulant therapy in reducing embolic stroke and systemic emboli in patients with atrial fibrillation without rheumatic heart disease.
To compare the effectiveness of various drugs and drug combinations in suppressing complex ventricular arrhythmias, and to evaluate their safety.
To assess the benefits of a new method of cardiopulmonary resuscitation, SC-V CPR (simultaneous compression and ventilation CPR) in terms of short and long-term survival and lessened cerebral dysfunction.
