During the initial phase of the World Health Organization (WHO) "Community Control Program of Hypertension" in Italy, 1190 subjects with high blood pressure derived from a general population random sample (5856 people of both sexes, aged 20 to 64 years) were enrolled in a hypertension register. At the registration visit (RV), each of them gave case history details and underwent a complete clinical examination, blood and urine tests, and a standard 12-lead electrocardiogram (ECG). All the ECGs were read by a single coder, using the second version of the Minnesota Code (MC). We calculated the prevalence of electrocardiographic codes according to sex, age, and the state of antihypertensive treatment. The overall prevalence of electrocardiographic abnormalities (i.e., all codes except 1:0 and isolated 9:4) was 40.8% with a slightly higher prevalence in males than in females: 42.4% versus 39.4%. Codes related to left ventricular hypertrophy (LVH) (3:1 or 3:3) were also more frequent in males (21.2%) than in females (14.5%) but not those related to ischemia (4:1-4:3 or 5:1-5:3). In fact, group 4 codes were present in 4.0% of males and 16.1% of females; group 5 codes, in 5.7% of males and 18.1% of females. Abnormal codes generally increased with increasing age, but those related to LVH did not follow this general rule in males. In fact, in the age class 20-29 years, codes 3:1 were found in 11.1% and codes 3:3 in 17.5% of the subjects, whereas the corresponding frequencies in the oldest age group (60-64 years) were 15.2% and 12.4%, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)
在世界卫生组织（WHO）意大利“高血压社区控制项目”的初始阶段，从普通人群随机样本（5856名年龄在20至64岁的男女）中选取的1190名高血压患者被纳入高血压登记册。在登记访视（RV）时，他们每人都提供了病史细节，并接受了全面的临床检查、血液和尿液检测以及标准的12导联心电图（ECG）检查。所有心电图均由一名编码员使用明尼苏达编码（MC）第二版进行解读。我们根据性别、年龄和抗高血压治疗状态计算了心电图编码的患病率。心电图异常（即除1:0和孤立的9:4外的所有编码）的总体患病率为40.8%，男性患病率略高于女性：42.4%对39.4%。与左心室肥厚（LVH）相关的编码（3:1或3:3）在男性中（21.2%）也比女性中（14.5%）更常见，但与缺血相关的编码（4:1 - 4:3或5:1 - 5:3）并非如此。事实上，4组编码在4.0%的男性和16.1%的女性中出现；5组编码在5.7%的男性和18.1%的女性中出现。异常编码通常随年龄增长而增加，但与LVH相关的编码在男性中并不遵循这一普遍规律。实际上，在20 - 29岁年龄组中，3:1编码在11.1%的受试者中出现，3:3编码在17.5%的受试者中出现，而在最年长年龄组（60 - 64岁）中相应的频率分别为15.2%和12.4%。（摘要截取自250字）
