A summary of the prevalence and impact of first‐degree AV block in various populations. Findings in studies including healthy individuals, community‐based studies and studies including patients with concomitant diseases. Notably, the prevalence of first‐degree AV block seems to increase with age and more advanced clinical state. Likewise, the affect of first‐degree AV block on outcome and clinical state is primarily seen in the older and/or more comorbid populations. AF = atrial fibrillation; AVI = first‐degree AV block; CHD = coronary heart disease; CRT = cardiac resynchronization therapy; HF = heart failure; PM = pacemaker.
