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).
A-V block or heart block - First-degree A-V block does not cause any symptoms. Second-degree A-V block causes an irregular pulse or slow pulse. Third-degree A-V block can cause a very slow heartbeat, dizziness and fainting. VT - Non-sustained VT may not cause any symptoms or cause a mild fluttering in the chest. Sustained VT usually causes lightheadedness or loss of consciousness and can be lethal. Ventricular fibrillation - This causes absent pulse, unconsciousness and death.
