Second Degree Type I AV Block 2:1 AV block Some P waves conduct to the ventricles on this ECG tracing, however it is clear that some do not. There does appear to be a prolonging PR interval before ...

If no P waves can be seen and the QRS complexes ... second-degree type I or second-degree type II AV block (see 2:1 AV block ECG Review). A posterior wall MI shows ST depression, not elevation ...

5,6 It is possible that such cases of SCD could be avoided using electrocardiogram (ECG) for early ... prolonged P-wave duration imparted a HR of 1.32 (P=.04) to 2.05 (P=<.001).
