“…It is also known that there is a relationship between different cardiovascular pathologies and SSNHL 21 . In a case-controlled study, it was found that the incidence of SSNHL was higher in individuals of families with cardiovascular events compared to the individuals of families with no cardiovascular events 22 .…”

“…The segmented short-term symbolic dynamics (SSD) was introduced in order to describe nonlinear aspects within longterm RR time series applying a 24-hour segmentation algorithm in an enhanced way [45,69]. Therefore, the related time series were segmented in both 1 min overlapping and non-overlapping time windows of 15 min, 30 min or 60 min duration.…”

“…LZ77 was modified by Baumert et al in 2004 [37] to analysis heart rate time series called the compression entropy (H c ). in the field of spontaneous fluctuations of cardiovascular oscillations entropy based methods were applied to investigate fetal development [38], to determine age effects on the autonomic system [39][40][41], in differentiating pathological states from healthy states [42][43][44][45][46], for monitoring cardiac autonomic function [34,47], in typifying the effects of a pharmacological treatment [48][49][50][51], and in predicting risk [37,52].…”

Complexity and Nonlinearity in Cardiovascular Signals

Methods from nonlinear dynamics have shown new insights into alterations of the cardiovascular system under various physiological and pathological conditions, and thus providing additional prognostic information. In this chapter prominent complexity methods of non-linear dynamics as symbolic dynamics, Poincaré plot analyses, and compression entropy are introduced and their algorithmic implementations and application examples in clinical trials are provided. Especially, we will give their basic theoretical background, their main features and demonstrate their usefulness in different applications in the field of cardiovascular and cardiorespiratory time series analyses. IntroductionLinear time and frequency domain measures are often not sufficient enough to quantify the complex dynamics of physiological systems and their related time series. Therefore, various efforts have been made to apply nonlinear complexity measures to analyze, e.g. the heart rate variability (HRV) [1]. These approaches differ from the traditional time-and frequency domain HRV analyses because they quantify the signal properties instead of assessing only the magnitude or the frequency power of the heart rate time series. They assess the self-affinity of heartbeat fluctuations over multiple time scales (fractal measures); the regularity/irregularity or randomness of heartbeat fluctuations (entropy measures); the coarse-grained dynamics of HR fluctuations based on symbols (symbolic dynamics) and the heartbeat dynamics based on a simplified phase-space embedding [1].Symbolic dynamics is based on a coarse graining of the dynamics of a signal. The time series (in our cases the ECG or the noninvasively recorded blood pressure curve) are transformed into symbol sequences with symbols of a given alphabet. Some detail information is lost but the coarse dynamic behavior retains and

“…In der Arbeit finden sich dazu aber keine näheren Ausführungen, insbesondere nicht, wie die "Hörschärfe" gemessen wurde. Eine Arbeit aus Jena will anhand von Daten bei 23 Hörsturzpatienten (verglichen mit 10 Normalhörenden) bei den Patienten eine veränderte autonome Kreislaufregulation gefunden haben[24]. Erfasst wurde die Kreislaufregulation mit einem EKG, das in Beziehung gesetzt wurde zu kontinuierlichen Blutdruckmessungen; erfasst wurde so die Kombination und Kopplung verschiedener kardiovaskulärer Faktoren, die sehr aufwändig statistisch ausgewertet wurde.…”

Hearing loss is one of the most dominant handicaps in modern societies, which additionally very often is not realized or not admitted. About one quarter of the general population suffers from inner ear hearing loss and is therefore restricted in communicational skills. Demographic factors like increasing age play an important role as well as environmental influences and an increasing sound and noise exposure especially in leisure activities. Thus borders between a "classical" presbyacusis - if it ever existed - and envirionmentally induced hearing loss disappear. Today restrictions in hearing ability develop earlier in age but at the same time they are detected and diagnosed earlier. This paper can eventually enlighten the wide field of inner ear hearing loss only fragmentarily; therefore mainly new research, findings and developments are reviewed. The first part discusses new aspects of diagnostics of inner ear hearing loss and different etiologies.

Altered Autonomic Regulation as a Cardiovascular Risk Marker for Patients With Sudden Sensorineural Hearing Loss

Abstract: ISSHL patients show an altered autonomic regulation. At least a subgroup of ISSHL patients seems to exist where a vascular impairment might play an important role in the pathogenesis of this disease.
