Sentence examples for cardiac beat from inspiring English sources

Likewise, in PCG signals, murmurs appear overlapped with the cardiac beat, and sometimes cannot be easily distinguished even by the human ear [3].

It demonstrates that the ICP wave is related to the cardiac beat and is disturbed by noise, which makes it technically challenging to extract the single ICP wave because its feature points cannot be located accurately.

In the synchrogram the phase values of the AWV observed in correspondence of the R-wave peak on the ECG was drawn as function of the cardiac beat number.

The MR sequence consisted of a clinically utilized imaging protocol, namely a 2D TurboFLASH saturation recovery gradient echo sequence (TE = 1 ms, TR = 164 ms, Flip angle = 10o, slice thickness = 6 mm, pixel spacing = 1.875 mm, matrix size 144 × 192 voxels, with temporal resolution of 1 image per cardiac beat).

The MR perfusion sequence consisted of a clinically utilized protocol, namely a 2D TurboFLASH saturation recovery gradient echo sequence (TE = 1 ms, TR = 164 ms, Flip angle = 10°, slice thickness = 8 mm, pixel spacing = 1.875 mm, matrix size 144 × 192 voxels, with temporal resolution of 1 image per cardiac beat).

The width of sliding window was w = f s/2f, and the sliding coefficient was δ = f s/2f, which was determined by the sampling frequency f s and the cardiac beat period f;   (4) Calculate module mini-max values of ICP signal in every sliding window as the feature points of the single ICP waves.

The lowest acceptable mean aortic pressure (MAP) and pulse pressure after defibrillation and regain of spontaneous cardiac beating (ROSB) was set by protocol consensus to 50 and 15 mmHg, respectively.

Targeted knockdown of the adenylate kinase-dependent energetic and AMP signaling cascade disrupted maturation of mitochondrial networks and myofibrillogenesis, precluding formation and function of organized cardiac beating structures.

Thus, knockdown of three major adenylate kinase isoforms early in stem cell specification compromises subsequent development of functional cardiac beating areas.

To gain mechanistic insight into causes of functionally deficient cardiac beating areas, cardiomyocytes were isolated from embryoid bodies after knockdown of AK1, AK2 and AK5 isoforms.

Control embryoid bodies had normal beating areas with high mitochondrial density (Fig. 6E), however AK1-AK2-AK5 siRNAs transfembryoidbodies bodies were unable to form organized cardiac beating areas and displayed low mitochondrial density (Fig. 6F).
