    摘要: An intracardiac electrogram (IEGM) or other suitable electrical cardiac signal is sensed. Values representative of a pre-symptomatic physiologic response to a hypoglycemic event are derived from the cardiac signal. Then, hypoglycemia is detected based on the values representative of the pre-symptomatic physiologic response. In one example, both temporal morphological parameters and spectral parameters affected by pre-symptomatic hypoglycemia are derived from the cardiac signal. Hypoglycemia is then detected based on a combination of the temporal and spectral parameters using, e.g., a linear discriminator. By detecting hypoglycemia based on parameters affected by pre-symptomatic hypoglycemia, suitable warnings can be generated and therapies initiated before the condition becomes symptomatic.

    摘要: Techniques are provided for estimating electrical conduction delays with the heart of a patient based on measured immittance values. In one example, impedance or admittance values are measured within the heart of a patient by a pacemaker or other implantable medical device, then used by the device to estimate cardiac electrical conduction delays. A first set of predetermined conversion factors may be used to convert the measured immittance values into conduction delay values. In some examples, the device then uses the estimated conduction delay values to estimate LAP or other cardiac pressure values. A second set of predetermined conversion factors may be used to convert the estimated conduction delays into pressure values. Techniques are also described for adaptively adjusting pacing parameters based on estimated LAP.

    摘要: A method for trending heart failure measures cardiogenic impedance (CI) and obtains signals representing estimates for or direct measurements of at least one of cardiac volume and pressure of the heart when the CI measurements were obtained. The method identifies correction factors based on the signals and applies the correction factors to the contractility estimates. A system for trending heart failure includes a contractility module to determine contractility estimates from CI measurements taken along at least a first vector through a heart, and a collection module to receive signals representing estimates for or direct measurements of at least one of cardiac volume and pressure of the heart when the CI measurements were obtained. The system further includes a factor module to identify correction factors based on the signals and a correction module to apply the correction factors to the contractility estimates.
