    摘要: Techniques for transmitting diagnostic information stored in an implantable medical device (IMD) based on patient hospitalization are described. For example, the IMD may transmit higher resolution diagnostic information to a clinician and/or an external device during a hospitalization period to aid the clinician in evaluating heart failure treatment and when discharge is proper. This higher resolution diagnostic information may include one or more patient metrics automatically generated and transmitted by the IMD at least once every two hours. During a post-hospitalization period, the IMD may transmit lower resolution diagnostic information to a clinician that indicates a risk level of re-hospitalization. The lower resolution diagnostic information may include the risk level and/or patient metrics once a day, for example. In this manner, the IMD transmitted diagnostic information may be tailored to the specific heart failure monitoring needed by the patient.

    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.

    摘要: A medical device performs a method to classify a cardiac rhythm. Differences between cycle lengths in a first heart chamber are determined during an established time interval. Evidence of ectopy associated with irregular coupling intervals is detected from the signal during the established time interval. A rhythm classification output corresponding to a second heart chamber at the expiration of the established time interval is provided in response to the consecutive cycle length differences and the evidence of ectopy associated with irregular coupling intervals.
