In the current issue of the Canadian Journal of General Internal Medicine (CJGIM), McIntyre and Seifer have identified the clinical benefits of cardiac resynchronization therapy (CRT) for patients with heart failure and conduction abnormalities (QRS > 130 msec). These benefits include a reduction in mortality and hospitalization. They also point out that the individual probability of benefiting from a CRT is variable amongst patients. For example, the larger the QRS interval the greater the potential benefit.
