“…Smaller studies investigated HRT in a large variety of pathologies ranging from Chagas' disease (121,122), children with dilated cardiomyopathy (123), children with adenotonsillar hypertrophy (124) and obesity (125). Among other findings, HRT was found to be impaired in patients with overt hyperthyroidism compared with control patients (126).…”

This consensus statement has been compiled on behalf of the International Society for Holter and Noninvasive Electrophysiology. It reviews the topic of heart rate turbulence (HRT) and concentrates on technologies for measurement, physiologic background and interpretation, and clinical use of HRT. It also lists suggestions for future research. The phenomenon of HRT refers to sinus rhythm cycle-length perturbations after isolated premature ventricular complexes. The physiologic pattern of HRT consists of brief heart rate acceleration (quantified by the so-called turbulence onset) followed by more gradual heart rate deceleration (quantified by the so-called turbulence slope) before the rate returns to a pre-ectopic level. Available physiologic investigations confirm that the initial heart rate acceleration is triggered by transient vagal inhibition in response to the missed baroreflex afferent input caused by hemodynamically inefficient ventricular contraction. A sympathetically mediated overshoot of arterial pressure is responsible for the subsequent heart rate deceleration through vagal recruitment. Hence, the HRT pattern is blunted in patients with reduced baroreflex. The HRT pattern is influenced by a number of factors, provocations, treatments, and pathologies reviewed in this consensus. As HRT measurement provides an indirect assessment of baroreflex, it is useful in those clinical situations that benefit from baroreflex evaluation. The HRT evaluation has thus been found appropriate in risk stratification after acute myocardial infarction, risk prediction, and monitoring of disease progression in heart failure, as well as in several other pathologies.

“…The relationship between ATH and other diseases such as cardiovascular and pulmonary disorders was reported in previous studies [1][2][3][4]. It is well known that ATH is one of the most common causes of upper respiratory tract obstruction, obstructive sleep apnea (OSA) and hypoxia in children [2].…”

“…Reduced heart rate variability parameters observed both preoperatively and early after operation may be considered as an indication for intervention. Yilmaz et al studied HRV on children having adenotonsillar hypertrophy, and reported that the prevalence of arrhythmias, HRV values were not changed signifi cantly in the post-operative period (p>0.05) (11). However as can be seen clearly from the parameters, there is a complex relationship between the heart rate, heart rate variability and autonomic nervous system in children with severe upper airway obstruction.…”

Objective: Heart rate variability (HRV) is a noninvasive index of neural activity of the heart. This study assessed the heart-rate variability response in children with severe upper airway obstruction. Material and Methods:A prospective trial was carried out in 15 children with severe adenoid and/or tonsil hypertrophy, compared to 15 age matched healthy children in order to attempt to relate such changes. Frequency domain measurements of the high and low frequency bands and the ratio low frequency/high frequency were derived from Holter electrocardiography recordings and computed by Fast Fourier analysis for fi ve minute intervals. Time domain measurements were derived from 24 hour Holter recordings.Results: All spectral analysis of heart rate variability was altered in both preoperative and postoperative (three months after the operation) recordings compared to the control group. In both groups, time domain indices were signifi cantly lower compared to the control group. Mean R-R values were signifi cantly reduced in pre and postoperative groups compared with control group, with the night time mean R-R values being signifi cantly lower (p<0.05). These results indicate the increased frequency domain parameters in two groups. Conclusion:In this study, patients demonstrated altered volume loads and autonomic response. Further studies are needed to assess when such cardiac fi ndings normalize upon relief of the upper airway obstruction.
