Cardiac arrhythmia is a group of conditions characterized by irregular, slow or fast heartbeat. It can be of four principal types- supraventricular tachycardias, bradyarrhythmias, ventricular arrhythmias and extra beats. Often, there are no noticeable symptoms in these diseases. However in serious cases, shortness of breath, chest pain, lightheadedness and passing out can occur. In other cases, cardiac arrest, stroke and heart failure may occur. An electrocardiogram and Holter monitor can prove to be definitive tests for cardiac arrhythmia. These conditions can be effectively treated with medications, medical procedures and surgery. Medications such as beta blockers and agents, and interventions such as the insertion of pacemakers and surgery may be used to restore normal heart rhythm. For severe symptoms of arrhythmia, cardioversion or defibrillation may be performed. This book contains some path-breaking studies revolving around cardiac arrhythmia. It unravels the recent studies in the mechanism pathways and management strategies of cardiac arrhythmia. For all readers who are interested in such studies, the case studies included in this book will serve as an excellent guide to develop a comprehensive understanding.
