I think hypokalemia is incorrectly listed as one of the causes of first degree AV block. My ECG handbook says it is hyperkalemia that can cause first degree AV block (and some internet sources confirm this).
Patients typically have a pre-existing LBBB or bifascicular block, and the 2nd degree AV block is produced by intermittent failure of the remaining fascicle (âbilateral bundle-branch blockâ). In around 75% of cases, the conduction block is located distal to the Bundle of His, producing broad QRS complexes.
