Blocked p wave
WebFor first-degree block, conduction is slowed without skipped beats. All normal P waves are followed by QRS complexes, but the PR interval is longer than normal (> 0.2 second). For third-degree block, there is no relationship between P waves and QRS complexes, and the P wave rate is greater than the QRS rate. WebImpulse conduction from the atria to the ventricles may be abnormally delayed or even blocked. These conditions are referred to as atrioventricular (AV) blocks, which are subdivided according to the …
