In electrocardiography, the PR interval is the period, measured in milliseconds, that extends from the beginning of the P wave (the onset of atrial depolarization)...

This analysis calculates features such as the PR interval, QT interval, corrected QT (QTc) interval, PR axis, QRS axis, rhythm and more. The results from...

in the AV node forms much of the PR segment on the ECG, and part of atrial repolarization can be represented by the PR segment. The distal portion of the...

combination of palpitations and when an electrocardiogram (ECG) show a short PR interval and a delta wave. It is a type of pre-excitation syndrome. WPW syndrome...

The prediction interval for any standard score z corresponds numerically to (1 − (1 − Φμ,σ2(z)) · 2). For example, Φ(2) ≈ 0.9772, or Pr(X ≤ μ + 2σ) ≈ 0...

the PR interval on consecutive beats followed by a blocked P wave (i.e., a dropped QRS complex). After the dropped QRS complex, the PR interval resets...

is defined by progressive prolongation of the PR interval, with a resulting dropped beat (the PR interval gets longer and longer until a beat is finally...

In Bayesian statistics, a credible interval is an interval used to characterize a probability distribution. It is defined such that an unobserved parameter...
