Abstract :
This paper introduces a method of analysis of short-term heart rate variability control during the evolution of ischemic transient attacks by autoregressive (AR) spectral identification. Signals are obtained from ECG Holter recordings of patients with two different ischemic pathologies: Syndrome X, which is believed to be due to coronary microvascular dysfunction, and Chronic Stable Angina. Parameters such as the power and the carrier frequency of the VLF, LF and HF bands are considered. Some of these parameters may describe characteristic different behaviors of the cardiovascular control system during the two ischemic pathologies, in the attempt to keep a stable neurovegetative state
