the PR interval (└┘) is much shorter (0.36 sec) than the baseline PR interval, meaning that the QRS complex is not the result of the P wave—the P wave is not conducted. Rather, this QRS
The PR interval before the dropped beat is the longest (340ms), while the PR interval after the dropped beat is the shortest (280ms).Short PR interval (<120ms)A short PR interval is seen with: Preexcitation syndromes AV nodal (junctional) rhythm.Pre...

There are many features and attributes of the ECG signal that can be measured without the use of overly complex feature extraction algorithms, such as the heart rate and rhythm, PR interval, the ST segment, the QT segment, and the U, J, P, R, S, T waves just to name a few (Refer...

As evident from the figure, the normal heart axis is between –30° and 90°. If the axis is more positive than 90° it is referred to as right axis deviation. If the axis is more negative than –30° it is referred to as left axis deviation. The axis is calculated (to the neares...
His initial ECG appeared to have an ectopic P-wave with a lengthening PR interval consistent with second degree AV block – Mobitz Type I. But closer inspection showed a faster, independent atrial rate. The patient was diagnosed with ectopic atrial bradycardia with complete AV block and ...
