摘要
A device for delivering pacing therapy includes an atrial and ventricular leads, sensing circuitry connected to the leads for detecting depolarizations, and pulse generation circuitry for delivering ventricular pacing pulses based on sensed atrial depolarizations. The device includes control circuitry for controlling the pulse generation circuitry in a first mode in which the pulse generation circuitry delivers atrial synchronized pulses to both the right and left ventricular leads in response to each atrial depolarization sensed. In response to a detected atrial arrhythmia, the control circuitry causes the pulse generation circuitry to deliver atrial synchronized ventricular pacing pulses in response only to selected atrial depolarizations.
