PR interval(measured from the beginning of the P wave to the first deflection of the QRS complex). Normal range 120 – 200 ms (3 – 5 small squares on ECG paper). QRS duration(measured from first deflection of QRS complex to end of QRS comple...
The characteristic features of Wolff-Parkinson-White syndrome are a short PR interval (<120ms), broad QRS and a slurred upstroke to the QRS complex, the delta wave.Lown-Ganong-Levine syndrome The features of Lown-Ganong-Levine syndrome LGL syndrome are a very short PR interval with normal P...

I had my ECG done today and its is showing a low PR interval of 119ms. The diagnosis shown on the ECG was Sinus Rhythm and short PR interval My HR is 90bpm, P dur 88ms, QRS dur 114ms, QT/QTC int 320/393ms I am worried whether it is normal or I have to worry and take som...
In this work, we have investigated the records in the MIT-BIH Arrhythmia Database and found that the minimum RR-interval is greater than 90 samples (0.25 s), so we set the refractory period to 90. The refractory period mechanism can effectively reduce the FP. In the meanwhile, to reduce...
depolarization during ventricular contraction. The direction of the depolarization (and thus the electrical axis) is generally alongside the heart’s longitudinal axis (to the left and downwards). Figure 38 shows the coordinate system where the green area displays the range of the normal heart axis...
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...
No significant differences were found in other P-wave parameters such as Delta-HR, Delta-QRS interval, Delta-QTc interval, Delta-PR interval, Delta-P-area, Delta-P-index, Delta-PWDI, Delta-PWDaVR, Delta-PWDaVL, Delta-PWDV1, Delta-PWDV2, Delta-PWDV3, Delta-PWDV4, Delta-PWDV6, Delta...
