The presence and timing of the different deflections on the EKG reflect the highly coordinated opening and closingof ion channels in the cardiacmyocytes. A typical action potential in ventricular myocytes is shown inFig 30.2, with the different phases of the action potential labeled as phases 0–...
Figure 5.4.8.Conduction system of the heart. The heart beat originates in the SA node at the junction of the venae cavae with the right atria. Excitation spreads through the atrial muscle to the AV node, which connects to the bundle of His. This conducts the excitation across the annulus...
the ECG signal, and the signal of the respiration sensor. If a signal exhibits a high signal quality and more than 90% of the recording shows a clearly visible signal, it is labeled as “A”. A medium quality signal is labeled as “B” whereas a recording...
E Beating rate (BPM), Spike amplitude, FPDcF, and conduction velocity of COs and HOs in each group through MEA recording. All data were shown as fold-change, as mean ± SD, by 2-way ANOVA (n = 3). A significant difference of all graphs is indicated by #,*p < 0.05...

Chord diagram showing relationships between gene ontology (GO) terms and DEGs. Enrichment analysis was performed on the set of DEGs found in all zebrafish embryo exposure (0.5 mg/L, 1 mg/L, 2 mg/L, and 10 mg/L) relative to the control. Select GO terms in all exposures (FDR corrected...
The data was compiled from several databases and labeled with the letters A through F. The given data had been contaminated by a variety of noise sources and that even in some of the recordings, it was impossible to distinguish between what was normal and what was abnormal in the data [57...
Region information for each heartbeat of DATPD peak detection is labeled on the heart rate in bottom panel (e). 2.2.6. New Peak Correction for Non-AF Windows Peak Correction for PAC/PVC Subjects Now we are in the step F in Figure 1. The next step involves PAC/PVC detection so that...
Another approach is to generate labels for an unlabeled dataset based on the portion of data that is labeled. Yet another approach is to use training from a different problem or a different dataset to generate labels for these data. Such techniques are used to improve the learning accuracy of...
that the validity of the extrapolation from laboratory calibration to field energy expenditure can be effectively tested, but heart-rate measurement is likely to remain a useful technique for comparing the relative energy expenditures of study groups when economics preclude the use of doubly labeled ...
