Patent Images
1. A method comprising:
- monitoring a first heart rate; and
detecting a first sinus tachyarrhythmia episode preceded by the first heart rate;
when the first sinus tachyarrhythmia episode is detected;
determining how quickly a first onset to the first sinus tachyarrhythmia episode occurs by monitoring at least one time interval and calculating how quickly the first onset to the first sinus tachyarrhythmia episode occurs using the time interval; and
automatically providing a congestive heart failure indication using information about the first heart rate and how quickly the first onset to the first sinus tachyarrhythmia episode occurs.

Abstract
An indication of an actual or potential heart failure condition is computed. One example includes monitoring a first heart rate preceding a first onset of a first sinus tachyarrhythmia episode. Upon detecting the first sinus tachyarrhythmia episode, the indication is automatically provided using information about the first heart rate and how quickly the first onset occurs.

27. An apparatus comprising:
-
a heart rate monitor circuit configured to detect a first heart rate and a second heart rate; a sinus tachyarrhythmia episode detection circuit configured to detect a first sinus tachyarrhythmia episode preceded by the first heart rate, and to detect a second sinus tachyarrhythmia episode preceded by the second heart rate; means for determining how quickly a first onset to the first sinus tachyarrhythmia episode occurs by monitoring at least one time interval and calculating how quickly the first onset to the first sinus tachyarrhythmia episode occurs using the time interval; and means for automatically providing a congestive heart failure indication using an indication that the first onset occurs more quickly than a specified onset threshold together with an indication that a first heart rate exceeds a specified threshold heart rate, wherein the first heart rate precedes the first onset to the first sinus tachyarrhythmia episode. - View Dependent Claims (28, 29)
