Cardiac Resynchronization Therapy (CRT) is an advanced medical intervention designed to improve the heart’s pumping efficiency in individuals with certain types of heart failure. This innovative treatment involves the implantation of a specialized device, known as a CRT device or biventricular pacemaker, which synchronizes the contractions of the heart’s chambers. In heart failure patients, the heart’s electrical impulses may become disorganized, leading to inefficient pumping and symptoms such as fatigue and shortness of breath. CRT works by coordinating the timing of the heart’s contractions, optimizing its performance and enhancing blood flow throughout the body. This therapy has proven particularly beneficial for individuals with heart failure and electrical conduction abnormalities, significantly improving their quality of life by alleviating symptoms and reducing hospitalizations. CRT represents a remarkable advancement in cardiac care, offering renewed hope for those with compromised heart function.
