A set of \(m\)-vectors \(X\left(1\right), X\left(2\right),\dots , X\left(N-m+1\right)\) in \({R}^{m}\) is formed, where \(X\left(i\right)=\left[x\left(i\right), x\left(i+1\right),\dots , x(i-m+1)\right], i=1,\dots , N-m+1\). These vectors repre...
Both records, which contain premature ventricular contractions, illustrate that our algorithm performs effectively on rendered digital vectors. Clinical assessment of the interpretability accuracy To evaluate the clinical performance of our methods, we conducted a comparison between the interpretability achieved...
Signal analysis is a domain which is an amalgamation of different processes coming together to form robust pipelines for the automation of data analysis. When applied to the medical world, physiological signals are used. It is becoming increasingly common in today’s day and age to be working wi...

The median absolute change in BNP over time was 178 pg/mL (IQR 52-532), and the median sampling interval was 106 days (IQR 27-357). We evaluated interval, duration, and axis metrics from the P, QRS, and T vectors from the raw digital ECG and found 8 co-varied with BNP changes, ...
The electrical activity of the heart can be observed from the horizontal plane and the frontal plane. The ability of a lead to detect vectors in a certain plane depends on how the lead is angled in relation to the plane, which in turn depends on the placement of the exploring lead and ...
SIFT methodology was proposed by Lowe in 199939 in order to solve the issue of scaling and rotation invariance in the feature extraction process. From the image, SIFT extracts a large collection of local feature vectors, each of which is resistant to changes in illumination, scale, translation,...
Frontal Plane Axis Shortcuts When we speak of axes and vectors, we are usually referring to themean QRS axis in thefrontalplane– much more so than in the horizontal plane (where it’s more properly called “rotation” rather than “axis”). We are also concerned with theP axis and the...
