WebShort PR interval (i.e. PR interval shorter than 2nd percentile, see Normal values for Pediatric ECG) suggests pre-excitation. The principles of pre-excitation in children are the same as for adults. For details, refer to Pre-excitation and Wolff-Parkinson-White Syndrome. Prolonged PR interval suggests AV block. WebThe hallmark of both RBBB and LBBB is the QRS duration which is by definitions 120 ms or longer. The distinction between RBBB and LBBB is simple, as illustrated in this figure.

A ventricular impulse is 'dropped' and, following this, AV conduction recovers to its baseline optimal level and the cycle repeats itself.

Mobitz type 2 is more serious, because it is usually chronic and tends to progress to third-degree AV block. Moreover, cardiac output may be reduced if many impulses are blocked.

WebThe normal PR interval is from 120 ms to 200 ms in length. This is measured from the initial deflection of the P wave to the beginning of the QRS complex. [3] In first-degree heart block, the AV node conducts the electrical activity more slowly. This is seen as a PR interval greater than 200 ms in length on the surface ECG.
