Management of cardiac arrhythmias has undergone major changes in the last few years. In the first part of this review, general principles of arrhythmia diagnosis are discussed. New techniques such as event recording and signal-averaged electrocardiography have a significant role in the clinical management of arrhythmias. Many new antiarrhythmic drugs are now available. Suppression of premature ventricular contractions to prevent malignant ventricular arrhythmias has been demonstrated to be an ineffective strategy. Implantable defibrillators and radio frequency ablation have revolutionized the treatment of arrhythmias. Differentiation of various supraventricular tachycardias has become very important since some these arrhythmias may be cured by radiofrequency ablation. Diagnosis and treatment of common supraventricular arrhythmias are discussed.
