    摘要: Diastolic function is monitored within a patient using a pacemaker or other implantable medical device. In one example, the implantable device uses morphological parameters derived from the T-wave evoked response waveform as proxies for ventricular relaxation rate and ventricular compliance. In particular, the magnitude of the peak of the T-wave evoked response is employed as a proxy for ventricular compliance. The maximum slew rate of the T-wave evoked response following its peak is employed as a proxy for ventricular relaxation. A metric is derived from these proxy values to represent diastolic function. The metric is tracked over time to evaluate changes in diastolic function. In other examples, specific values for ventricular compliance and ventricular relaxation are derived for the patient based on the T-wave evoked response parameters.

    摘要: An implantable medical device includes a lead configured to be located proximate to the left ventricle (LV) of the heart, the lead including multiple LV electrodes to sense cardiac activity at multiple LV sensing sites. The a detection module to detect an arrhythmia that represents at least one of a tachycardia and fibrillation based at least in part on the cardiac activity sensed at the multiple LV sensing sites. The ATP therapy module to identify at least one of an ATP configuration or an ATP therapy site based on the cardiac sensed activity at the LV sensing sites, the ATP therapy module to control delivery of antitachycardia pacing (ATP) therapy at the ATP therapy site. The ATP therapy module delivers a stimulus to electrodes at one or more of an LV site, right ventricular (RV) site and right atrial (RA) site, the detection module to sense evoked responses at the LV sensing sites, the ATP therapy module to designate the ATP therapy site to include at least the LV sensing site with a shortest activation time relative to the one or more LV site, RV site and RA site where the stimulus is delivered.
