On ECG, this is defined by a progressive prolongation of the PR interval, with a resulting dropped beat the PR interval gets longer and longer until a beat is finally dropped, or skipped. However, one important consideration when diagnosing AV blocks from ECGs is the possibility of pseudo- AV blocks which are due to concealed junctional extrasystoles. In a second-degree AV block, the impairment results in a failure to conduct an impulse, which causes a skipped beat. Blue tracing indicates resulting ECG tracing. An ECG is used to differentiate between the different types of AV block. The heart rate produced by the ventricles is much slower than that produced by the SA node.
