We present the first reported case of transient left bundle branch block (LBBB) occurring during electroconvulsive therapy (ECT). LBBB is an important clinical finding, as it is associated with a significant increase in mortality. Physicians providing ECT should be aware of the significance of new-onset LBBB; it may occur during treatment.
