摘要： An implantable medical device (100) is connectable to an epicardial left ventricular lead (30) having at least one epicardial electrode (32, 34, 36) and a myocardium penetrating catheter (50) with at least one endocardial electrode (52, 54) and present in a lumen (35) of the lead (30). The device (100) comprises a pulse generator controller (130) that controls a ventricular pulse generator (140) to generate pulses to be applied to the epicardial (32, 34, 36) and endocardial (52, 54) electrodes. The controller (130) uses an endocardial-to-epicardial time interval or epicardial-to-endocardial time interval to coordinate endocardial and epicardial activation of the left ventricle to thereby achieve cardiac pacing that closely mimics the natural electrical activation pattern of a healthy heart (15).

摘要： An implantable medical device (100) is configured for generating a cardiogenic impedance signal representative of the cardiogenic impedance of at least a portion of a heart (10) of a subject (20) during at least a portion of cardiac cycle. A moment processor (132) calculates a moment parameter value based on the cardiogenic impedance signal. The moment parameter is representative of a weighted sum of impedance amplitudes within a time window centered at defined time instance within the cardiac cycle. The weights of the impedance amplitudes are further dependent on the length in time between the defined time instance and the point of time of the associated impedance amplitude. The moment parameter is of high diagnostic value and is employed by an arrhythmia classifier (132) in order to classify a detected arrhythmia of the heart (10), such as discriminate between hemodynamically stable or unstable arrhythmias and/or supraventricular or ventricular tachycardia.

摘要： An implantable medical device, IMD, (100) comprises atrial and ventricular sensing units (125, 135) for sensing atrial or ventricular electric events. The IMD (100) also comprises atrial and ventricular pulse generators (120, 130) for generating atrial or ventricular pacing pulses. A controller (140) controls the operation of the IMD (100) according to a first mode, in which the ventricular pulse generator (130) is prevented from generating a back-up pulse if an evoked response detector (133) fails to detect evoked response to a delivered ventricular pacing pulse, and a second mode, in which the ventricular pulse generator (130) is controlled to generate a back-up pulse if no evoked response is detected following delivery of a ventricular stimulating pulse. The controller (140) switches operation from the first mode to the second mode based on the evoked response detector (133) failing to detect an evoked response to a delivered ventricular pacing pulse.

摘要： A late potential detecting system (1) comprises an implantable medical device (100) connected to at least one cardiac lead (200) having implantable electrodes (211-218) positioned at different sites of a ventricle myocardium. A sampling unit (120) of the implantable medical device (100) records electrogram samples for the different implantable electrodes (211-218) to get different sample sets. The electrogram samples of the sample sets are time synchronized and magnitude potential representations of the potential data of the electrogram samples are determined. The magnitude potential representations of the time synchronized electrogram samples are then co-processed and used for determining a parameter that is indicative of any late potentials of the monitored ventricle (25).
