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 multiple cardiac cycles. A transform processor (132) generates a spectrum signal by applying a time-to-frequency transform to the cardiogenic impedance signal. The spectrum signal is processed by a distribution processor (133) configured to calculate a distribution parameter indicative of a distribution in at least a portion of the spectrum signal. The calculated distribution parameter is of high diagnostic value and is employed by an arrhythmia classifier (134) 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.
