心电波形相关知识27正常心电图波形FignormalECGwaveform下面是各个波所代表的含义32反映的是心房除极产生的电活动代表左右心房去极过程的电位变化。波形小而圆钝光滑历时00811S波幅不超过025MV。两心房复极化过程所产生的电位变化称为Ta波它通常与PT段重叠在一起且波幅很低在心电图上不易辨认。R段是以P波为起点至...
However, the interpretation of the ECG waveform and where it starts to deviate from the normal waveforms is poorly defined for the clinical practice. To support the anatomical relationship of the ECG, the PathECG has been developed as part of the CineECG tool, expanding the view on the ECG....

21,22. The lethal electric field threshold (LET) needed to achieve irreversible electroporation of cells depends on the specific waveform applied23,24,25, but is independent of electrode geometry
(over the cardiac cycle, synchronized with the QRS complex of ECG) were taken in scattered locations throughout the LV and RV epicardium. We used measured electrical data to spatially and temporally modulate the heterogeneity of active contraction. When modeling MI, contraction was shut down in ...
SCG is thus being revised as an easy to use, non-invasive measuring technique of the cardiac performance and health status. The signal is deterministic and even though it is more detailed than, for instance, the electrocardiogram (ECG), the SCG fiducial points related to characteristic events in...
Each waveform consisted of systolic, v, diastolic, and a waves. The systolic wave occurred 0.4 sec later than the QRS complex of the ECG and was always antegrade. The v wave was always retrograde without flow reversal. The diastolic wave was always antegrade. The a wave was always ...
Fig.1Typicalpulsewaveform 脉搏波的波形特性由其波峰的高度与位置, 以及脉搏波周期长度决定.为了在不严重影响脉 搏波波形特征的前提下,尽量减少脉搏波存储、传 输中的数据量,学界提出对脉搏波进行数学建模, 以减少数据量 [3] .现有的建模方法多使用高斯函 数对脉搏波进行拟合,将大量的脉搏波数据简化 至几个高斯...
