Signal-averaged electrocardiography shows promise for identifying sudden cardiac death risk, but requires standardization of methods and criteria.
May inform sudden cardiac death risk assessment; leaves open standardization needs before clinical adoption.
Signal-averaged electrocardiography has shown great promise as an adjunct in identifying patients at risk for sudden cardiac death. Clearly, much research remains to be done. Methods and criteria must be standardized so studies can be compared and the most effective ways in which to use this technology can be determined.
