متن کاملCardiac cycle length modulates cardiovascular regulation that is dependent on previous beat contraction history.
Previous studies of the beat-to-beat regulation of left ventricular performance in the intact cardiovascular system have shown that the performance of the left ventricle on any one beat is influenced by the mechanical events of the previous beat, so-called previous beat contraction history. The general hypothesis investigated in this study is that previous beat contraction history occurs becaus...
متن کاملEffect of endotoxemia on heart rate dynamics in rat isolated perfused hearts
Introduction: Beat-to-beat variation in heart rate shows a complex dynamics, and this complexity is changed during systemic inflammatory response syndrome (e.g. sepsis). It is not known whether or not cardiac pacemaker dynamical rhythm is affected by sepsis. The aim of this study was to investigate heart rate dynamics of isolated heart as well as expression of pacemaker channels (HCN) in a r...
متن کاملبررسی آماری سری زمانی ضربان قلب
In this paper, we study the statistical approaches to diagnose the heart by using the heart rate of individuals. First we review some well known methods and then we consider two new approaches. We analyse the extended self-similarity (ESS) and recursive model in the beat-to-beat fluctuations in the heart rates of healthy subjects as well as those with congestive heart failure. These concepts pr...
