The functions and normal range values for these electrolytes are important, and if an electrolyte is at an extreme low or high, it can be fatal. Heart Detail Picture The heart is composed of specialized cardiac muscle, and it is four-chambered, with a right atrium and ventricle, and an ...
The major problem with the ECG diagnosis of electrolyte imbalance is not the negative ECG with abnormal serum values. But the production of similar changes by other conditions in patients with normal serum values. Hyperkalemia The initial effect of acute hyperkalemia is the appearance of peaked T ...

The normal P-R interval is three to five small squares or 0.12 to 0.20 seconds. Long PR intervals might indicate a first-degree AV block presence, while short intervals accompany disorders of AV acceleration such as Wolf-Parkinson-White (WPW) syndrome. QRS Complex. "QRS" represents ventricular...
Once the software is running in datalogging mode, it simply reads the analogue voltage presented by the ECG front-end and sends it via serial link to OpenLog. In use, the values range between 50 and 700. I could have increased this range/resolution nearer to 1024 by adding an external vo...
If 1.2 was used as the critical 'normal' value of QRS duration ratio in (V2+V3)/(V4+V5) specificity was 90.8% for males and only 79.5% for females.Conclusion: QRS duration ≥110ms in the right precordial lead V1, V2 or V3 seems to be the best marker for discriminating healthy ...
The normality of distribution of EKGvman and EKGvauto values was tested using the Kolmogorov-Smirnov test. In the case of a normal distribution, the parametric Pearson test was used to assess correlation. EKGvman and EKGvauto were also compared using Bland-Altman analysis [11]. A receiver ...
values used by ICC: 0=perceptual, 1=relative, 2=saturation, 3=absolute. Should be 1 for normal use cases, it adapts white to match that of different RGB models which is the best practice. Using 3 may change the color of white. 0 and 2 will have the same effect as 1 because this ...
