摘要： A method of assessing lesion quality of an ablated tissue region comprising ablating at least a portion of the tissue region. The reactance of the ablated tissue region is measured at a plurality of frequencies. The lesion quality of the ablated tissue region is determined based on the measured reactance. For example, an untreated tissue reactance value and a predetermined thermally treated tissue region reactance threshold may be determined. The measured reactance at each of the plurality of frequencies is compared to the threshold to determine the lesion quality of the thermally treated tissue region. The thermal treatment of the tissue may be modified based on the lesion quality determination.

摘要： In an implantable medical device that provides atrial and ventricular pacing in an atrial-based pacing mode, longer periods of time are permitted for intrinsic AV conduction to occur. By monitoring the patient's AV delay under these circumstances, useful information is obtained that can be correlated to other patient conditions or symptoms.

摘要： A programmer including a user interface, and techniques for programming a rate responsive implantable medical device using such a programmer and user interface are presented. The programmer may retrieve currently programmed rate response parameters and optimization target values of an implantable medical device. The programmer may display the currently programmed rate response parameters and optimization target values via a user interface. The programmer may also generate a current rate response curve and a current target rate histogram, and display the current rate response curve and current target rate histogram via the user interface. The programmer may receive changes to the displayed currently programmed rate response parameters and/or target values made by a user via the user interface, generate a pending rate response curve and/or a pending target rate histogram based on these changes, and display the pending rate response curve and/or pending target rate histogram via the user interface.

摘要： An implantable device having enhanced capabilities for monitoring a patient's heart rate and respiration trends over extended periods of time is disclosed. The information collected by the implantable device may be stored and telemetered to an associated external device such as a device programmer for display and analysis. Heart rates are measured by measuring the time intervals between sensed depolarizations of a chamber of the patient's heart and preceding sensed depolarizations or delivered pacing pulses. Intervals may be measured in the ventricle and/or atrium of the patient's heart. According to another aspect of the invention, an implanted impedance sensor is employed to monitor minute ventilation. The heart rate and minute ventilation data is used to develop long-term trend data used for diagnostic purposes. In one embodiment of the invention, heart interval and minute ventilation measurements are taken only during defined time periods of the night and/or day when the patient is at rest. A sensor such as an activity sensor or metabolic rate sensor may be used to confirm patient inactivity.
