Cardiac resynchronization therapy

As mentioned in Chapter 1, one relatively new approach in cardiac pacing is biventricular pacing or cardiac resynchronization. This is pacing of patients with congestive heart failure to maintain synchrony between the interventricular septum of the left ventricle and the lateral wall of the left ventricle, thus improving cardiac output, and improving the patient's symptoms and possibly patient longevity (Fig. 7-1).
