These are drugs used to prevent or treat irregularities of cardiac rhythm. Nearly 3 out of 4 patients of acute myocardial infarction (MI) and about half of those given a general aesthetic exhibit at least some irregularity of cardiac rhythm. Arrhythmias are the most important cause of sudden cardiac death. However, only a few arrhythmias need to be treated with antiarrhythmic drugs. Abnormal automaticity or impaired conduction or both underlie cardiac arrhythmias. The generation and propagation of cardiac impulse and properties of excitability and refractoriness are described on p. 492 to 494. The high level evidence supporting the use of antiarrhythmic drugs during CPR for shockable cardiac arrest is limited and showed no benefit for critical outcomes of survival at hospital discharge, survival with favorable neurological function and long-term survival. Future high quality resrearch is needed to confirm these findings and also to evaluate the role of administering antiarrhythmic drugs in children with shockable cardiac arrest, and in adults immediately after ROSC.Electrocardiogram (ECG or EKG): A picture of the electrical impulses traveling through the heart muscle. An ECG is recorded on graph paper,through the use of electrodes (small, sticky patches) that are attached to your skin on the chest, arms and legs.Ambulatory monitors, such as the Holter monitor.Stress test: A test used to record arrhythmias that start or are worsened with exercise. This test also may be helpful to determine if there is underlying heart disease or coronary artery disease associawith an arrhythmia.Echocardiogram:
