This study focuses on the dynamic pattern of heart rate variability in the frequency range of respiration, the so-called respiratory sinus arrhythmia. Forty experimental time series of heart rate data from four healthy adult volunteers undergoing a paced respiration protocol were used as an empirical basis. For pacing-cycle lengths >8 s, the heartbeat intervals are shown to obey a rule that can...
Theorists have staked out two ostensibly opposing views of human crying as either an arousing behavior that signals distress or a soothing behavior that reduces arousal after distress. The present study examined whether these views of crying might be reconciled by attending to physiological changes that unfold over crying episodes. Sixty female students watched neutral and cry-eliciting films w...
Objective: Respiratory sinus arrhythmia (RSA) refers to heart rate oscillations synchronous with respiration, and it is one of the major representations cardiorespiratory coupling. Its strength has been suggested as a biomarker monitor different conditions, diseases. Some approaches have proposed quantify RSA, but unclear which performs best in specific scenarios. The main objective this study ...
OBJECTIVES This study sought to evaluate respiratory disturbances as potential triggers for arrhythmia in patients with sleep-disordered breathing (SDB). BACKGROUND SDB is associated with an increased risk of atrial fibrillation and nonsustained ventricular tachycardia (NSVT) as well as a predilection for sudden cardiac death during nocturnal sleeping hours. However, prior research has not es...
