How to Follow Resynchronized Paced Patients
Biventricular stimulation is a new promising therapy for the treatment of moderate-to-severe heart failure in patients refractory to drug treatment and with contractile dyssynchrony due to conduction delay. The principle on which the resynchronization therapy is based is the reactivation of homogeneous and synchronized contraction by means of atrial-biventricular stimulation. The restoration of greater contraction synchrony seems to produce beneficial effects in the short (e.g., improvement in cardiac output, reduction of mitral regurgitation, increase of dP/dt, reduction of pulmonary wedge pressure) and the medium term (e.g., reduction of left ventricular diameters, increase of ejection fraction, reduction of mitral regurgitation, and reduction of sympathetic activity).
