In addition, many intraoperative ECG monitors have filters for removing electrocautery noise. In pediatric anesthesiology practice, we often note the appearance of elevated T waves—specifically, an increase in their height—with the use of such filters, even though no actual clinical change has ...
a greater interval between the R wave of the ECG and the S wave, a reduced interval between the S and D waves, and an increase in the S-wave shift (SWS), a novel metric that characterizes the shift in timing of the S wave away from the R wave of the ECG and toward the D wave...

This gating error was easily corrected by changing guidance lead to increase the amplitude of the R wave and decrease that of the T wave.关键词: ECG-gated myocardial SPECT gating error tall T waves DOI: 10.1097/RLU.0b013e3181662baa 被引量: 10 ...
Modulation of magnetoencephalography alpha band activity by radiofrequency electromagnetic field depicted in sensor and source space Article Open access 03 December 2021 Dataset of concurrent EEG, ECG, and behavior with multiple doses of transcranial electrical stimulation Article Open access 27 Octobe...
ECG signal. Regarding memory, representation of the complete ECG signal by an equivalent diagnostic word appreciably reduces the memory size required. Figure 1 shows the P, Q, R, S and T waves on an electrocardiogram tracing (lead 1) illustrating 使用对ECG信号的一个简单的数学分析因此是有利的...
Attentional lapses occur commonly and are associated with mind wandering, where focus is turned to thoughts unrelated to ongoing tasks and environmental demands, or mind blanking, where the stream of consciousness itself comes to a halt. To understand the neural mechanisms underlying attentional lapses...
In the present paper a mathematical model of the ECG wave has been proposed, assuming the human body to be equivalent to a cylindrical composite dielectric and conducting medium and the heart to be a harmonic bio-signal generator located in this medium. This model has been utilised to explain...
