Abstract

A 52-year-old male with ischemic cardiomyopathy and severe ventricular dysfunction underwent coronary artery bypass grafting and left ventricular reconstruction (Dor operation). The patient developed acute onset of incessant ventricular tachycardia in the early postoperative period that was refractory to therapy with class I antiarrhythmic agents, and multiple attempts at electrical cardioversion were required. A combination of intravenous nifekalant hydrochloride and enteral amiodarone was elected as treatment for this recurrent incessant ventricular tachycardia. Nifekalant hydrochloride was administered as a loading dose (0.3 mg/kg/5 min), followed by an intravenous infusion (0.4 mg/kg/hr). Several days after initiating therapy, the patient no longer experienced episodes of ventricular tachycardia, and there was no compromise in hemodynamics. We conclude that nifekalant hydrochloride is a useful agent for suppression of ventricular tachycardia in patients with severe left ventricular dysfunction, especially during the early postoperative period.

Antiarrhythmic Agents: Mechanisms of Action

Understanding the mechanism of action of antiarrhythmic agents is essential in developing new medications as treatment of cardiac arrhythmias is currently limited by the reduced availability of safe and effective drugs.

Brain Ischemia

Brain ischemia is a condition in which there is insufficient blood flow to the brain to meet metabolic demand. Discover the latest research on brain ischemia here.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
