Treatment of heart failure by Cardiac Resynchronization Therapy (CRT) through Biventricular Pacing (BVP): A review article

The aim of this review study is to introduce the cardiac resynchronization therapy through biventricular pacing in treatment of heart failure. More than 22 million peoples worldwide suffer from congestive heart failure (CHF). As a result of the lack of synchronized contraction، both within and between the ventricles، blood moves through the heart and body at a slower rate. Heart failure impacts on almost all aspects of the quality of life of patients، particularly on mobility. Despite treatment advances such as lifestyle changes، medication and heart surgery، up to %40 of patients with CHF suffer an arrhythmia that further reduces the heart’s ability to beat properly. Cardiac Resynchronization Therapy (CRT) is a new، adjunctive and effective therapy that can relieve CHF symptoms by improving the synchronization of the heart’s contractions. According to the studies، after BVP، heart contractility، and left ventricular ejection fraction and stroke volume increase، the incidence of cardiac arrhythmias decreases and some aspects of quality of life such as exercise tolerance improves. Cardiac resynchronization therapy (CRT) along with other medical options can be safely performed and can relieve CHF symptoms by improving the coordination of the heart’s contractions.
