Background: An abnormal Q wave is usually defined as an initial depression of the QRS complex having a duration of ≥40 ms and amplitude exceeding 25% of the following R wave in any contiguous leads on the 12-lead electrocardiogram (ECG). However, much smaller Q waves are sometimes ...
Finally we described the utility of a careful evaluation of P wave duration and dispersion measured on standard ECG and signal-averaged ECG (SAECG) recordings as potential atrial fibrillation predictors and markers of history of paroxysmal atrial fibrillation....
where\(b\in {{\mathbb{R}}}^{d}\)is a bias vector. After the linear projection, we apply element-wise nonlinear activation functions\(\sigma :{{\
52 found that apamin decreased membrane voltage, increased intracellular Ca2+ levels, and increased aldosterone secretion in a dose-dependent manner from human adrenocortical H295R cells. In contrast, 1-ethyl-2-benzimidazolinone, an agonist of SK channels, antagonized the actions of apamin and ...

Utilize equipment that will give you the most information with least problems, for example, ultrasound Doppler probe for heart rate and rhythm, end-tidal capnography, and ECG are easy to use. Pulse oximetry can be temperamental but still useful when a reliable pulse wave is obtained (irregular ...

Successful ventricular rapid pacing appears in the ECG tracings, as indicated by a narrow QRS that converts to a wide QRS with shortened R–R intervals. Use of a device with programmable pacing voltage via primary transmission coil RF output power modulation allowed for further studies. On day...
