The PR interval starts at the onset of the P-wave and ends at the onset of the QRS complex (Figure 1). It reflects the time interval from the start of atrial depolarization to the start of ventricular depolarization. The PR interval is assessed in order to determine whether impulse conducti...

facilitating early intervention to reduce mortality and morbidity. At the same time, we aim to improve the interpretability of the model so that medical professionals
Each QRS complex is preceded by a normal P wave Normal P wave axis: P waves upright in leads I and II, inverted in aVR The PR interval remains constant QRS complexes < 100 ms wide (unless co-existent interventricular conduction delay present)Normal heart rates in childrenNew...
between the genome and transcriptome varies based on tRNA (f) and rRNA (g) secondary structures. Theyaxis represents the log2-transformed ratio of clone-VAF in RNA to clone-VAF in DNA. Mutations with clone-VAF lower than 0.01 were excluded. One-sided Wilcoxon test. IQRs, interquartile ...
In normal sinus rhythm, what does the P-wave, the PR interval, QRS complex, and QT interval reflect?ECG:An ECG, or electrocardiogram, is an electrical readout of the heart which measures the electrical output of all heart chambers during cardiac cycles. Th...
Which statement best describes why atrial depolarization is usually not detected on a normal ECG? a. It occurs at the same time as the QRS complex. b. The electrodes cannot be placed high enough on the chest to detect the atria. c. The atr...
Somatic mutations spontaneously accumulate in normal cells throughout an individual’s lifetime, from the first cell division2,3,4,5. Previous studies on somatic mosaicism have primarily focused on nucleotide variants6,7,8,9,10,11. More complex structural events remain less explored owing, in par...
ECG Signal Denoising and QRS Complex Detection by Wavelet Transform Based Thresholding Biomedical signals like heart waves commonly change their statistical property over time and are highly non stationary signals. For the analysis of this kind of signals wavelet transform is a powerful tool. Electrocard...
