Abstract： Objective： To analyze the relationship between different Chinese medicine syndrome types and electrocardiogram in patients with hypertension complicated with coronary heart disease. Methods：First of all，the patients with hypertension and coronary heart disease from June 2018 to June 2019 were classified according to TCM syndrome differentiation until they met the requirements of 6 groups with no less than 20 cases in each group，each group had 20 cases. Relevant examination was conducted through 12-lead electrocardiograph.Relevant indexes and relationship between different Chinese medicine syndrome types were compared. Results： Among 120 cases of clinical patients with hypertension complicated with coronary heart disease，myocardial ischemia，arrhythmia，left ventricular high voltage，and left ventricular hypertrophy accounted for 41.67% (50/120)， 28.33% (34/120)， 19.17% (23/120)， and 10.83% (13/120) respectively. Myocardial ischemia was mainly related to obstruction of static blood type(65.00%)， cold congealing in the heart vessel type(50.00%) ， the heart qi deficiency type(50.00%) ， and internal obstruction of phlegm turbidity type(45.00%). The proportion of each syndrome type of arrhythmia ranged from 20.00% to 35.00% .Left ventricular high voltage was mainly related to heart- kidney yang deficiency type(30.00%) and heart- kidney yin deficiency type(35.00%). Left ventricular hypertrophy was mainly related to internal obstruction of phlegm turbidity type(20.00% )， heart- kidney yang deficiency type(15.00%) ， and heart-kidney yin deficiency type(15.00%).Obstruction of static blood type was the most common in positive patients with prolonged Q- T interval accounting for 34.17% (41/120) and positive patients with S- T segment depression accounting for 42.50%(51/120). The QRS complex dispersion of different Chinese medicine syndrome types from high to low was as follows：obstruction of static blood type，internal obstruction of phlegm turbidity type，heart-kidney yang deficiency type，cold congealing in the heart vessel type，heart qi deficiency type，and heart-kidney yin deficiency type(P＜ 0.05). Conclusion： There is an internal relationship between different Chinese medicine syndrome types and electrocardiogram in clinical patients with hypertension dominated by myocardial ischemia complicated with coronary heart disease.The main syndrome type is obstruction of static blood type.The manifestations of electrocardiogram include prolonged Q-T interval，S-T segment depression，and even increased QRS complex dispersion.
