Indications and Usage

In patients without structural heart disease, propafenone HCl is indicated to prolong the time to recurrence of- paroxysmal atrial fibrillation/flutter (PAF) associated with disabling symptoms.- paroxysmal supraventricular tachycardia (PSVT) associated with disabling symptoms.As with other agents, some patients with atrial flutter treated with propafenone have developed 1:1 conduction, producing an increase in ventricular rate.

Concomitant treatment with drugs that increase the functional AV refractory period is recommended.The use of propafenone in patients with chronic atrial fibrillation has not been evaluated.

Propafenone should not be used to control ventricular rate during atrial fibrillation.Propafenone is also indicated for the treatment of-documented ventricular arrhythmias, such as sustained ventricular tachycardia, that, in the judgment of the physician, are life-threatening.

Because of the proarrhythmic effects of propafenone, its use with lesser ventricular arrhythmias is not recommended, even if patients are symptomatic, and any use of the drug should be reserved for patients in whom, in the opinion of the physician, the potential benefits out-weigh the risks.Initiation of propafenone treatment, as with other antiarrhythmics used to treat life-threatening ventricular arrhythmias, should be carried out in the hospital.Propafenone, like other antiarrhythmic drugs, has not been shown to enhance survival in patients with ventricular or atrial arrhythmias.
Heart Diseases -- Pathological conditions involving the HEART including its structural and functional abnormalities.

Paroxysmal atrial fibrillation --

Symptoms -- An indication that a person has a condition or disease. Some examples of symptoms are headache, fever, fatigue, nausea, vomiting, and pain.

Atrial Flutter -- 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).

Atrial Fibrillation -- Abnormal cardiac rhythm that is characterized by rapid, uncoordinated firing of electrical impulses in the upper chambers of the heart (HEART ATRIA). In such case, blood cannot be effectively pumped into the lower chambers of the heart (HEART VENTRICLES). It is caused by abnormal impulse generation.

Ventricular arrhythmia -- Irregular heart beat resulting from a pathologic process in the cardiac ventricles.--2004

Sustained Ventricular Tachycardia -- An electrocardiographic finding of ventricular tachycardia greater than 30 seconds in duration.


Propafenone HCl is contraindicated in the presence of uncontrolled congestive heart failure, cardiogenic shock, sinoatrial, atrioventricular and intraventricular disorders of impulse generation and/or conduction (e.g., sick sinus node syndrome, atrioventricular block) in the absence of an artificial pacemaker, bradycardia, marked hypotension, bronchospastic disorders, manifest electrolyte imbalance, and known hypersensitivity to the drug.
Congestive heart failure -- complication of heart diseases; defective cardiac filling and/or impaired contraction and emptying, resulting in the heart's inability to pump a sufficient amount of blood to meet the needs of the body tissues or to be able to do so only with an elevated filling pressure.

Cardiogenic shock -- Shock resulting from diminution of cardiac output in heart disease.

Disease -- A definite pathologic process with a characteristic set of signs and symptoms. It may affect the whole body or any of its parts, and its etiology, pathology, and prognosis may be known or unknown.

Sick Sinus Syndrome -- A condition caused by dysfunctions related to the SINOATRIAL NODE including impulse generation (CARDIAC SINUS ARREST) and impulse conduction (SINOATRIAL EXIT BLOCK). It is characterized by persistent BRADYCARDIA, chronic ATRIAL FIBRILLATION, and failure to resume sinus rhythm following CARDIOVERSION. This syndrome can be congenital or acquired, particularly after surgical correction for heart defects.

Atrioventricular Block -- Impaired impulse conduction from HEART ATRIA to HEART VENTRICLES. AV block can mean delayed or completely blocked impulse conduction.

Electrolyte imbalance -- Higher or lower than normal values for the serum electrolytes; usually affecting NA, K, CHL, CO2, glucose, bun.

Hypersensitivity -- Altered reactivity to an antigen, which can result in pathologic reactions upon subsequent exposure to that particular antigen.
