The chemistry, pharmacology, pharmacokinetics, clinical efficacy, adverse effects, and dosage of sotalol hydrochloride are reviewed. The chemical name of sotalol hydrochloride is 4'-[1-hydroxy-2-(isopropylamino)ethyl]methanesulfonanilide monohydrochloride. Sotalol is a class III antiarrhythmic that
OBJECTIVE
To evaluate concentration-dependent effects of total extract of Ruta graveolens and its purified alkaloid fraction on the nodal basic and functional properties.
METHODS
In the present experimental study, we used the Langendorff model for perfusion of isolated rat hearts to determine the
Atrial fibrillation is the most common arrhythmia encountered in clinical practice. The associated hemodynamic changes can lead to symptoms of palpitations, fatigue, light-headedness, or dyspnea. Extensive research in the use of antiarrhythmic drugs has been performed both to facilitate the
The anti-arrhythmic activity of mexitil was studied in 36 patients with frequent, prognostically unfavourable ventricular extrasystoles of various etiology. Quantitative and qualitative assessment of rhythm disorders was accomplished by bicycle ergometry and ECG recording for 24 hours by means of
Atrial fibrillation is most the common sustained arrhythmia seen by the cardiologist. Therapy to prevent this arrhythmia is often prescribed so as to eliminate associated symptoms which include palpitations, fatigue, dizziness and presyncope, shortness of breath, congestive heart failure and emboli,
Although first described about 100yr ago, atrial fibrillation (AF) is now recognized as the most common of all arrhythmias. It has a substantial morbidity and presents a considerable health care burden. Improved diagnosis and an ageing population with an increased likelihood of underlying cardiac
Chronic heart failure (CHF) is a common and disabling syndrome with a poor prognosis. It is a major and increasing public health problem. Angiotensin-converting enzyme inhibitors, diuretics, and digitalis are the standards treatments for CHF. Other drugs, such as beta-blockers, spironolactone,
The pharmacotherapy currently recommended by the American College of Cardiology and the American Heart Association for heart failure (HF) is a diuretic, an angiotensin-converting enzyme inhibitor (ACEI), a beta-adrenoceptor antagonist and (usually) digitalis. This current treatment of HF may be
Treatment for chronic hepatitis C depends on the hepatitis C virus (HCV) genotype and the patient's clinical characteristics. A fixed-dose combination of ledipasvir + sofosbuvir has been authorised in the European Union for adults with HCV genotype 1 (HCV-1), HCV-3 or HCV-4 infection. Ledipasvir
Congestive heart failure is the most arrhythmogenic disorder in cardiovascular medicine. As left ventricular performance deteriorates and symptoms of dyspnea and fatigue become progressively more severe, nearly all patients with heart failure experience frequent and complex ventricular
Isolated dog hearts perfused with blood from a donor dogand driven at two heart rates were used to compare the effects of propranolol with those of its quaternary ammonium derivative on atrial, atrioventricular (AV) nodal, and His-Purkinje conduction. Propranolol slowed only AV-nodal conduction,
BACKGROUND
Pre-excitation is based on an accessory conduction pathway between the atrium and ventricle. The term Wolff-Parkinson-White (WPW) syndrome is used for patients with the pre-excitation/WPW pattern associated with AP-related tachycardia.
METHODS
We present a 52-year-old man with severe
Atrial fibrillation is the most common supraventricular tachyarrhythmia encountered in clinical practice, affecting over 5% of persons over the age of 65 years. A common pathophysiological mechanism for arrhythmia development is atrial distention and fibrosis induced by hypertension, coronary artery
BACKGROUND
Premature ventricular contractions (PVCs) are among the most prevalent arrhythmias. PVCs lead to haemodynamically insufficient heartbeats. Their presence is considered rather insignificant, but this widespread assumption is not supported by research evidence.
METHODS
We present three
Amiodarone is an effective treatment for atrial and ventricular arrhythmias, but its use is limited by a toxic adverse-effect profile. Although dronedarone has been touted as an antiarrhythmic agent devoid of both solid organ toxicity and proarrhythmic properties, its potential for prolonging
