Use of Homeopathy for Prevention of Atrial Fibrillation in Patients After Aortocoronary Bypass and Heartvalve Surgery With Heart-lung Machine
After heart surgery, about 30% of patients suffer from atrial fibrillation. Patients are randomized into two groups receiving either potentized Strychnos Nux vomica or placebo under double blind conditions. Postoperatively, ECGs are done to monitor cardiac rhythm.
Allocation: Randomized, Control: Placebo Control, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Medical and Biotech [MESH] Definitions
Rapid, irregular atrial contractions caused by a block of electrical impulse conduction in the right atrium and a reentrant wave front traveling up the inter-atrial septum and down the right atrial free wall or vice versa. Unlike ATRIAL FIBRILLATION which is caused by abnormal impulse generation, typical atrial flutter is caused by abnormal impulse conduction. As in atrial fibrillation, patients with atrial flutter cannot effectively pump blood into the lower chambers of the heart (HEART VENTRICLES).
Misunderstanding among individuals, frequently research subjects, of scientific methods such as randomization and placebo controls.
A cardiotonic glycoside obtained mainly from Digitalis lanata; it consists of three sugars and the aglycone DIGOXIGENIN. Digoxin has positive inotropic and negative chronotropic activity. It is used to control ventricular rate in ATRIAL FIBRILLATION and in the management of congestive heart failure with atrial fibrillation. Its use in congestive heart failure and sinus rhythm is less certain. The margin between toxic and therapeutic doses is small. (From Martindale, The Extra Pharmacopoeia, 30th ed, p666)
An effect usually, but not necessarily, beneficial that is attributable to an expectation that the regimen will have an effect, i.e., the effect is due to the power of suggestion.
An anticoagulant that acts by inhibiting the synthesis of vitamin K-dependent coagulation factors. Warfarin is indicated for the prophylaxis and/or treatment of venous thrombosis and its extension, pulmonary embolism, and atrial fibrillation with embolization. It is also used as an adjunct in the prophylaxis of systemic embolism after myocardial infarction. Warfarin is also used as a rodenticide.
A study to test the safety, tolerability, and efficacy of 4 regimens of vaniprevir + Peg-IFN and RBV as compared to placebo + Peg-IFN and RBV.
The purpose of the study is to compare how sitagliptin and glipizide lower blood glucose levels in patients with moderate and severe renal insufficiency.
The purpose of this study is to investigate the efficacy, safety, and tolerability of an investigational treatment for patients with Human Immunodeficiency Virus (HIV).
This study will evaluate if MK3614, given in multiple rising doses, is safe and tolerated in male subjects with mild to moderate hypertension.
This is a multicenter study to evaluate the efficacy and safety of MK0476 versus placebo in patients with chronic asthma who actively smoke cigarettes.
The objective of the present study was to assess the safety and effectiveness of vernakalant hydrochloride injection (RSD1235), a novel antiarrhythmic drug, for the conversion of atrial fibrillation (...
Background The risk of cardiovascular events among patients with atrial fibrillation is high. We evaluated whether irbesartan, an angiotensin-receptor blocker, would reduce this risk. Methods We rando...
OBJECTIVE: The aim of this study was to investigate the preliminary safety and efficacy of three doses of budiodarone in patients with paroxysmal atrial fibrillation....
This article reviews the role of placebo interventions and placebo effects in clinical practice. We first describe the relevance of different perspectives among scientists, physicians and patients on...
OBJECTIVES: We sought to clarify the efficacy of corticosteroid therapy for preventing atrial fibrillation (AF) recurrence after pulmonary vein isolation (PVI). BACKGROUND: The inflammatory process ma...
