Cardiac resynchronization therapy is the therapy of choice in patients with severe congestive heart failure and intraventricular conduction disorder. The effiacy has been proven in several clinical studies. The therapy improves both objective and subjective clinical parameters significantly. Conventionally the therapy is indicated in severe drug refractory heart failure (NYHA III-IV) with optimal drug treatment, increased QRS duration (≥120 ms), echocardiographic parameters (left ventricular ejection fraction at most 35%). Implementation of new methods (tissue Doppler echocardiography, CT, MRI, electroanatomical mapping) can help to select potentially responding patients. Individual optimization of therapy can be performed with non-invasive and invasive methods, the efficacy can be improved even in responding patients. As the number of implantations has not reached the demand yet, it is necessary to improve the number of procedures performed.
