The average duration and amplitude of the P-waves on ECG lead II, and the duration and amplitude of positive and negative deflections on ECG lead V1 were extracted during SR after cardioversion at the end of the index WPVI. P-wave terminal force in V1 (PTFV1) was computed as the ...
When comparing ECG characteristics between the two groups, PWD was significantly longer in the scar group (122.9 ± 18.5ms and 116.9 ± 28.0ms, p = 0.01). A multivariate analysis was performed, after adjustment of age, gender, LA diameter, the PWD was found to be an independent predictor ...
P-wave prolongation due to left atrial enlargement (LAE) is also present in patients with left ventricular hypertrophy where it becomes an important secondary criteria in its diagnosis by electrocardiography (ECG). Therefore, it is important to detect and properly interpret P-wave prolongation when ...

Participants were stratified according to P wave duration (<114 or ≥ 114 ms) and PNMMVD (i.e. coronary heart disease defined as ischaemic ECG changes and typical symptoms of angina pectoris, or claudication; yes or no). The Cox proportional hazards model was used to estimate the joint ...
In Figure 7, the P, Q, R, S, and T waves all appeared clearly; the peak-to-peak amplitudes of these ECG signals were all approximately 1900 arbitrary units (a.u.), and their SNRs showed similar values of around 32 dB. These experiments demonstrate that while it has a...

The metabolic response to starvation is characterised by a switch fromcarbohydratemetabolism to fat cmetabolism, in the context of a hypometabolic state, with minimised catabolism. 在低代谢状态下,对饥饿的代谢反应的特征是从碳水化合物代谢转变为脂肪代谢,分解代谢最小化。
UWS who received melatonin exhibited a higher relative spectral density of the alpha band in the frontal lobe compared to those who received placebo (Ftime-mel = 4.55,P = 0.033) and benefited for their prognosis after 6 months (PseudoR2 = 0.370,F = 12.03,P = 0.034)...
Percent recovery from baseline of the porcine equivalent of the N20 neurological wave. The horizontal line represents the median. No statistically significant differences were observed between groups with a significance set at p < 0.05. Full size image There was not a significant difference in ...
