We therefore aimed to investigate the influence of the location of a typical $AV$ bypass tract on the 12 lead ECG using a physiologically-detailed whole heart model of electrophysiology $(EP)$ that is capable of providing in-depth information on the underlying electrical mechanisms of $WPW$ Methods: In previous work, a physiologically-detailed model of whole heart $EP$ was built and personalized for a single subject to generate a realistic normal sinus rhythm. Locations of APs used were automatically inserted within the heart using universal ventricular coordinates (UVCs) to model a typical AV bypass tract. For every location, cardiac sources and 12 lead ECGs were computed using an efficient cardiac simulator. 12 lead ECGs were evaluated for clinical markers of $WPW$ Electrical mechanisms are explored for two locations exhibiting highest and lowest morphological differences in the 12 lead $ECG$. Results: Retrograde activation of the His-Purkinje System (HPS) that later merges with the wave-front stemming from normal activation of the $HPS$ is observed. Not all $APs$ resulted in 12 lead ECGs exhibiting morphological markers for $WPW$ under clinical evaluation.

The objective of this study is to evaluate the effects of noise on the signals in the selection of the regularization parameter $(lambda)$ by zero-order Tikhonov and L-curve optimization. Fourteen atrial fibrillation (AF) simulations were used for computing the ECGI with different noise levels (3, 10, 20, 30, and 40dB). Signals of real cardiac rhythms were also used to compute the $ECGI(3 AF, 2$ atrial flutters, 3 atrial pacing, 3 atrial sinus rhythm and 3 ventricular tachycardia). For simulations and patients, maximum L-curve curvature and $lambda$ were obtained and compared. The maximum curvature of the L-curve, noise level and optimal $lambda$ correlated for ${A}F$ simulations. Higher levels of noise resulted in smaller curvatures of the L-curve and the selection of higher values $of lambda$, reducing the amplification of noise when computing ECGI. Real cardiac signals of AF presented similar results in curvature and $lambda$ as the higher values of noise explored in simulations $(3dB, lambda > 10^{-6}$, curvature $< 1$). The noise of the signal proportionally affects to the reconstruction of ECGI. The given results show a methodology to obtain trustable ECGI maps based on the shape of the L-curve optimization.","PeriodicalId":117840,"journal":{"name":"2022 Computing in Cardiology (CinC)","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124574283","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}

The experiment contained two sections-10 minutes short exposure and a night of sleep. Fingertip PPG signal was recorded in the whole process. We carried out a comparative analysis for each subject in normal and hypoxic conditions. Result showed that the average K values in normoxic environment and hypoxic conditions for short exposure were 0.3456 and 0.3861 respectively, and for sleep were 0.3081 and 0.3419 respectively. Significance level p were both less than 0.05. Variations of PPG waveform parameter K reflect the changed peripheral vascular resistance. In hypoxic environment, the raised K value tallied with the physiological mechanism that hypoxic exposure increases peripheral vascular resistance.

However, the relation between HP and QT variability in athletes has been poorly investigated. Therefore, we aimed at estimate transfer function gain (TFG) to typify the relationship between HP and QT variability in athletes. We acquired electrocardiogram in 18 half-marathon runners while supine (REST) and during active standing (STAND) at baseline (B) and at a 10-year follow up (FU). The TFG was computed as the ratio between the modulus of the cross-spectral density between HP and QT divided by the power spectral density of HP in low frequency (LF, 0.04-0.15 Hz, TFGLF) and high frequency (HF, 0.15-0.4 Hz, TFGHF) bands. We found that TFGHF was lower at FU compared to B both at REST and during STAND. TFGLF increased during STAND compared to REST only at FU. The present work supports the use of the linear approach in the frequency domain to typify the cardiac control of athletes. In addition, the findings suggest that a moderate and regular physical activity through the years is beneficial as it favors a decrease of the cardiac sympathetic modulation.","PeriodicalId":117840,"journal":{"name":"2022 Computing in Cardiology (CinC)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115662324","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, the low quality of the fECG extracted from non-invasive abdominal recordings hampers its adoption in clinical practice. In this work, a new algorithm for the recovery of clean and morphologically preserved fECG signals from multi-channel trans-abdominal recordings is presented. The proposed method exploits optimal shrinkage and nonlocal median algorithms, along with a de-shape short-time Fourier transform-based detection, to recover high-quality fECG traces from a morphological perspective, while ensuring very high performance also in terms of fetal QRS detection. On a small dataset, composed of three real 20 min-long four-channel abdominal ECG recordings, a preliminary performance assessment of the proposed fECG extraction method in terms of fetal QRS detection capabilities revealed a median accuracy of 95.8% and F1 score of 97.9%. The obtained results suggest the possibility of successfully applying this approach for an effective non-invasive fECG extraction, deserving further investigations on larger real and synthetic datasets.","PeriodicalId":117840,"journal":{"name":"2022 Computing in Cardiology (CinC)","volume":"145 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114380864","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}

Mitochondrial ATP production is the main source of reactive oxygen species (ROS) and hence the regulation of ROS becomes an important issue in maintaining optimal ANS functionality. Humanin (HN), a mitochondrial-derived peptide, plays an important role in lowering OS. Sympathovagal balance was assessed in 124 healthy participants through heart rate variability (HRV) analysis and compared across changes in HN concentrations divided into quintiles, with values of HN ranging from 64.6 to 343.2 pg/mL. Significant differences included various frequency domain and nonlinear HRV parameters, particularly between first and fourth HN quintiles with p values < 0.001 for recurrence plot analysis (RPA), detrended fluctuation analysis (DFA) al and Poincaré plot ratio SD1/SD2. The results revealed non-monotonic relationships between measures of HRV and HN concentration. A mitohormetic type of relationship was observed with HRV features increasing and then decreasing with increasing HN concentration. These results are consistent with previous findings of the importance of HN levels in regulating OS and extend these by revealing a concomitant effect on the modulation of cardiac rhythm by the ANS.","PeriodicalId":117840,"journal":{"name":"2022 Computing in Cardiology (CinC)","volume":"128 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127087271","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}
