In a study of the prevalence of first-degree AV block in rural Northeast China (2017-2018) among 10,926 participants at least 40 years old, investigators noted the prevalence was 3.4% with a male predominance. [12] Independent risk factors for first-degree AV block included male sex, older age, taller height, elevated systolic blood pressure and triglyceride levels, reduced high-density lipoprotein cholesterol level, heart rate, and lack of regular exercise.
