DescriptionCardiac dysrhythmia is a heart rate disorder that manifests as an altered cardiac rhythm. It results from either abnormal pacemaker activity or a disturbance in impulse propagation, or both. Arrhythmias can be caused by various conditions including ischemia, hypoxia, pH disruptions, B adrenergic activation, drug interactions or the presence of diseased tissue. These events can trigger the development of ectopic pacemaker in the heart, which emit abnormal impulses at random times during the cardiac cycle. An arrhythmia can present itself as either bradycardia or tachycardia. Untreated arrhythmias may progress to atrial fibrillation or ventricular fibrillation. Treatment is aimed at normalizing cardiac rhythm by altering ion flow across the membrane. Antiarrhythmic agents can reduce arrhythmia related symptoms such as palpitations or syncope; however, they often have a narrow therapeutic index and can also be proarrhythmic. Lorcainide (Lorcainide hydrochloride) is a Class 1c antiarrhythmic agent that is used to help restore normal heart rhythm and conduction in patients with premature ventricular contractions, ventricular tachycardiac and Wolff-Parkinson-White syndrome. Lorcainide was developed by Janssen Pharmaceutica (Belgium) in 1968 under the commercial name Remivox and is designated by code numbers R-15889 or Ro 13-1042/001. It has a half-life of 8.9 +- 2.3 hrs which may be prolonged to 66 hrs in people with cardiac disease. Wolff-Parkinson-White syndrome (WPW) is a pre-excitation syndrome in which individuals are predisposed to supraventricular tachyarrhythmias (rapid and irregular heart beats). People with this condition have an extra or accessory atrioventricular conduction pathway that causes re-entry tachycardia. WPW is characterized by a short PR interval (<0.12 second) and a prolonged, slurred QRS complex (>0.12 seconds).
