ABSTRACT:
Exemplary methods and devices for determining whether fusion or pseudofusion have occurred. An exemplary method includes delivering a stimulus, sensing cardiac activity, determining whether the stimulus resulted in capture, and if the determining indicates that the stimulus did not result in capture, then, determining whether the sensed cardiac activity includes characteristics of native cardiac activity by comparing at least some of the sensed cardiac activity to a template. Accordingly, if the sensed activity includes native activity, then a diagnosis is made that the stimulus resulted in fusion or pseudofusion. Another exemplary method includes determining whether a stimulus resulted in capture, and if the determining indicates that the stimulus did not result in capture, then, adjusting sensitivity of a sensor and sensing cardiac activity using the sensor. According to this method, if cardiac activity is sensed, then a diagnosis is made that the stimulus resulted in fusion or pseudofusion. Various methods and/or devices are suitable for use with autocapture. Other methods, devices and/or systems are also disclosed.
