Heart-Rate Variability—More than Heart Beats?
Heart-rate variability (HRV) is frequently introduced as mirroring imbalances within the autonomous nerve system. Many investigations are based on the paradigm that increased sympathetic tone is associated with decreased parasympathetic tone and vice versa. But HRV is probably more than an indicator for probable disturbances in the autonomous system. Some perturbations trigger not reciprocal, b...
متن کاملEstimating ‘Lost Heart Beats’ Rather than Reductions in Heart Rate during the Intubation of Critically-Ill Children
PURPOSE Reductions in heart rate occur frequently in children during critical care intubation and are currently considered the gold standard for haemodynamic instability. Our objective was to estimate loss of heart beats during intubation and compare this to reduction in heart rate alone whilst testing the impact of atropine pre-medication. METHODS Data were extracted from a prospective 2-yea...
متن کاملHandling of Ectopic Beats in Heart Rate Variability Analysis Using the Heart Timing Signal
The problem of analyzing heart rate variability in the presence of ectopic beats is revisited. Based on the IPFM model and the closely related heart timing signal, a new technique is introduced which corrects for the occasional presence of such beats. The correction technique, which involves the occurrence times of a certain number of beats preceding the ectopic, is computationally very efficie...
متن کاملMy Heart Beats Only For
One of the most intriguing elements of Mohamed Soueid's film My Heart Beats Only For Her (2008) is the ambiguous narrative that lies somewhere between fiction and documentary. In this film a man named Hassan tries to retrace the steps of his father Hatem Hatem, a Lebanese revolutionary in the 1970s, on a journey from Beirut to Hanoi to Dubai. Soueid combines and interrelates these two seemingly...
