During the initial phase of the WHO "Community Control Programme of Hypertension" in Italy, 1,190 hypertensives (of both sexes, aged 20-64) were identified through the screnning of 5,856 people randomly selected from the whole population of the community of Camposampiero (Padova), and had a standard ECG tracing recorded. ECGs were all read according to the 2nd version of the Minnesota code (MC), by only one coder. First of all, the prevalence of the various items of MC in the two sexes was calculated. Absolutely normal ECGs (item 1-0) were found in 41.1% of the examined subjects; another 23.3% had only a shift of the transition zone to the right or to the left (items 9-4). Among pathological codes, the most frequent were those of class 3 relating to left ventricular hypertrophy (LVH) (i.e. 3:1 or 3:3) and those of classes 4, 5 and 7 relating to myocardial ischaemia (ISC) (i.e. 4:1-3 or 5:1-3 or 7-1). The overall frequencies of LVH and, respectively, of ISC (calculated by suitably grouping the above described items) were as follows. LVH: 21.3% in males (M), 14.6% in females (F); ISC: 5.7% in M, 18.1% in F. A significant (p less than 0.005) positive correlation with age was found both for LVH and ISC codes in F, only for ISC codes in M. A significant negative correlation between LVH codes and body mass index (BMI) was instead evident only in males.(ABSTRACT TRUNCATED AT 250 WORDS)
在意大利世界卫生组织“高血压社区控制项目”的初始阶段，通过从坎波桑皮耶罗（帕多瓦）社区全体居民中随机抽取5856人进行筛查，确定了1190名高血压患者（年龄在20至64岁之间，男女均有），并记录了标准心电图。所有心电图均由一名编码员按照明尼苏达编码（MC）第2版进行解读。首先，计算了男女两性中MC各项的患病率。在41.1%的受检者中发现心电图完全正常（项目1 - 0）；另外23.3%的受检者仅出现过渡区右移或左移（项目9 - 4）。在病理编码中，最常见的是与左心室肥厚（LVH）相关的3类编码（即3:1或3:3）以及与心肌缺血（ISC）相关的4、5和7类编码（即4:1 - 3或5:1 - 3或7 - 1）。LVH和ISC的总体发生率（通过对上述项目进行适当分组计算）如下。LVH：男性（M）为21.3%，女性（F）为14.6%；ISC：男性为5.7%，女性为18.1%。在女性中，LVH和ISC编码与年龄均呈显著正相关（p小于0.005），在男性中仅ISC编码与年龄呈显著正相关。相反，仅在男性中LVH编码与体重指数（BMI）呈显著负相关。（摘要截断于250字）
