WebFigure 1. Electrode positions on an ECG (EKG). When electrical activity (or depolarisation) travels towards a lead, the deflection is net positive. When the activity travels away from the lead the deflection is net negative. If it is at 90 degrees then the complex is ‘isoelectric’ i.e. the R and S wave are the same size. Webexcitation generates the P wave and this lasts 0.08 sec. There is a delay in the AV node itself, taking up another 0.04 sec., and then the excitation enters the common bundle of His. Thus the P-H interval (P to His bundle) takes up 0.12 sec. The procession down the intraventricular pathways is divided fur-ther; from His bundle to the right or ... ucw term times

It reflects conduction through the AV node. The normal PR interval is between 120 200 ms (0.12-0.20s) in duration (three to five small squares). If the PR interval is > 200 ms, first degree heart block is said to be present.

WebThe PR interval reflects whether impulse conduction from the atria to the ventricles is normal. The PR interval must not be shorter than 120 msec or longer than 220 msec. The PR segment is the flat line between the end of the P-wave and the start of the QRS complex. The PR segment reflects the time delay between atrial and ventricular activation.
