The waves on an ECG during a cardiac cycle include the P wave, QRS complex, and T wave. The P wave represents the depolarization of the atria of the...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a ques...
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 th
Furthermore, we show that variable expressivity of ECG features observed in LQTS2 patients can be explained by as little as 20% variation in the levels of ionic conductances that contribute to repolarization reserve. This has significant implications for interpretation of whole-genome sequencing data...
The exact mechanisms of such phenotypic ECG manifestations of the J wave, leading to poor prognosis, are explained by the electrocardiologic differential theory, i.e., bradycardia induces full recovery of Ito from the preceding AP, leading to an accentuated phase 1 notch and a delayed AP dome...
Each ECG and EEG segment, with a time series of 4 min, was used for signal processing and statistical analysis. The novel ideal of the procedure is emphasized, and details of the procedure are presented in the Methods section. This procedure is completely based on the linear and nonlinear ...

These applications are related, for example, to the estimation of Ion-Li battery parameters [5], structural health monitoring [28], rail vehicle running states [29], ECG Monitoring [30] or the eye blink detection [31]. All of those approaches use at least one ARM Cortex-M4 that includes...

Because color Doppler is a type of pulsed wave Doppler, it is limited by the Nyquist limit. In fact, color Doppler is limited more by the Nyquist limit (as compared with standard pulsed wave Doppler), which is explained by the fact that the pulse repetition frequency (PRF) is reduced when...
Praecordial ECG-mapping (forty-two unipolar leads) was carried out on sixteen patients with anterior acute myocardial infarction (AMI) and on ten control patients without AMI. The variability, chronometric changes and the error-of-measurement when measuring sigma ST, sigma Q and sigma R in an ...
