Abstract: Competing Interests: Declaration of competing interest No conflict of interest.
Loss of pacing capture of the right or left ventricle as well as prolongation of the device-defined LV latency can be automatically unmasked in Biotronik CRT-D devices by Home Monitory of the CRT pacing interrupt algorithm. These situations are associated with short intervals from a pacing stimulus to conducted ventricular activation. These intervals are relatively constant with device-defined latency while those from loss of capture are longer and may be more variable. The true LV latency interval should be re-evaluated whenever the device-defined latency is apparent and prolonged.
