In the clinical practice, changes of AC are considered to reflect long-term vascular changes, e.g. arterial stiffening associated with atherosclerosis. However, AC is often confounded by the changes (including short-term changes) in other cardiovascular characteristics, e.g. blood pressure, vasomotion and heart rate (HR). In this study, changes of AC were assessed in the context of potential confounders - systolic arterial pressure (SAP), total peripheral resistance (TPR) and HR perturbations during various physiological states (supine rest, orthostasis and cognitive load) in 56 young and healthy subjects. We observed that AC changes during orthostasis were associated with systemic vasoconstriction and increased HR while changes during cognitive load were associated with increased blood pressure and HR. These findings underline the importance of AC evaluation considering the changes in its confounders.","PeriodicalId":199691,"journal":{"name":"2022 12th Conference of the European Study Group on Cardiovascular Oscillations (ESGCO)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121890615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, many HRV parameters have been employed to distinguish ECGs with SR from those with atrial fibrillation (AF). However, studies on the diagnostic properties of HRV for AF detection differ both in the tested parameters and in the length of studied ECGs. We aimed to systematically test the diagnostic properties of selected HRV indices for differentiation between AF and SR in ECGs of a wide range of lengths between 5 to 300 s. We demonstrate that the diagnostic performance of HRV for the AF detection strongly depends on the length of the ECG, usually improving with longer recordings. The best diagnostic properties of all HRV indices have been found for pRR50 with the area under curve from 0.881 for 5 s to 0.980 for 300 s, and diagnostic odds ratio from 44 (5 s) to 421 (300 s). We conclude that the length of ECG recording and the selection of HRV parameters are crucial for the proper differentiation of AF from SR. Clinical Relevance- This study demonstrates that the ECG length determines the diagnostic properties and the cutoff values of HRV parameters for AF detection. Additionally, if RR intervals time series analysis is applied to differentiate AF from SR, pRR50 outperforms other HRV parameters used, regardless of the ECG length between 5 and 300 seconds","PeriodicalId":199691,"journal":{"name":"2022 12th Conference of the European Study Group on Cardiovascular Oscillations (ESGCO)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129711384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a separate analysis comparing episodes of apnea and normal breathing during sleep has not been per-formed, to characterize whether the increased sympathetic dominance is just due to the instantaneous autonomic response to each apnea or there is a sustained sympathetic activation. The HRV metrics evaluated are the temporal and frequency HRV indices, along with new spectral bands, recently identified as specific for pediatric patients diagnosed with OSA. Nonpar-ametric paired statistical test exhibits clear significant differ-ences in HRV, comparing for each patient values in apnea events and normal breathing during sleep and such findings are applicable for all HRV metrics except RMSSD and HF band power, whose significance during apnea events is questionable. While all previous studies analyzed HRV either for the over-night recordings or after removing the apnea events, results obtained in this work highlight the need to perform the analysis separately, both in apnea events and in normal breathing.","PeriodicalId":199691,"journal":{"name":"2022 12th Conference of the European Study Group on Cardiovascular Oscillations (ESGCO)","volume":"40 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132430975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a lot of information is lost especially if the RR tachogram is transformed to a binary representation. Here, we aim to complement measures of binary symbolic dynamics by properties closely related to the binary representation, i.e. runs of accelerations and decelerations of heart period as basic characteristics underlying heart rate variability. This approach is applied to 1079 RR tachograms from healthy subjects covering the entire adulthood (age range: 18 to 84 years). Each parameter was analyzed per age decade. The average RR interval increased at old age compared to the youngest age group (median RR interval 839 ms vs. 970 ms). SDNN was constant up to 39 years and declined for older subjects (56 ms vs. 36 ms). Binary symbolic indices were derived from acceleration and deceleration of heart period. P1V, i.e. binary patterns of length 3 with one variation, decreased for elderly (>70 years, 53,4%) compared to young ages (<29 years, 66,3%). At the same time P2V, i.e. binary patterns with two variations, increased (14,7% vs. 22,7%). The cumulative accelerations and decelerations were largest for youngest subjects and decreased subsequently and was low in the age group 40 to 49 years (accelerations: −73 ms vs. −37 ms, decelerations. 64 ms vs. 34 ms). The analysis of runs of accelerations and decelerations provides information complementing results from binary symbolic dynamics.","PeriodicalId":199691,"journal":{"name":"2022 12th Conference of the European Study Group on Cardiovascular Oscillations (ESGCO)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124641799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
