• Sommario/riassunto: Profiles potential treatment approaches for cardiac arrhythmias Cardiac arrhythmias of ventricular origin are responsible for the deaths of nearly half a million Americans each year while atrial fibrillation accounts for about 2.3 million cases per year, a rate that is projected to increase 2.5 fold over the next half century. Effectively managing these cardiac rhythm disorders remains a major challenge for both caregivers and the pharmaceutical industry. Filling a gap in the current literature, Novel Therapeutic Targets for Antiarrhythmic Drugs presents the latest treatments f
