The article provides new insights to cardiac resynchronization therapy (CRT), a method of treating chronic heart failure with cardiac biventricular pacing. The article covers the history of its development starting with the first attempts to eliminate heart dyssynchrony up to the present advances. Over the last decades, CRT has significantly improved, including both implantable devices and electrodes, and current CRT guidelines and indications. The article discusses serial changes in indications and selection criteria for patients based on the results of the recent clinical trials assessing its effectiveness. Evidence-based knowledge is presented for the CRT application in the routine clinical practice. Novel approaches and technologies aimed at improving the effectiveness of CRT are presented.
