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).
In the United States, the prevalence of first-degree AV block among young adults ranges from 0.65% to 1.6%. Higher prevalence (8.7%) is reported in studies of trained athletes. The prevalence of first-degree AV block increases with advancing age; first-degree AV block is reported in 5% of men older than 60 years.
