ABSTRACT
Objective:To understand the electrocardiogram and echocardiography examination results of population in key areas of unexplained sudden death in Yunnan Province (referred to as Yunnan sudden death).Methods:From 2014 to 2022, electrocardiogram examination was performed on population (including same incident cases, relatives of the cases, villagers of the affected villages, and control individuals) in key areas of Yunnan sudden death from May to October each year. Echocardiography examination was performed on relatives of the cases and villagers of the affected villages, and the types of electrocardiogram and echocardiography changes were sorted out and analyzed.Results:Electrocardiogram examination was conducted on 1 same incident case, 241 relatives of the cases, 464 villagers of the affected villages, and 99 control individuals, respectively. The types of electrocardiogram changes in the same incident case were Q-T interval prolongation and sinus tachycardia. A total of 17 types of electrocardiogram changes were detected in the relatives of the cases, mainly including sinus arrhythmia (12.45%, 30/241), sinus bradycardia (11.20%, 27/241), and left axis deviation (8.30%, 20/241). A total of 21 types of electrocardiogram changes were detected in the villagers of the affected villages, mainly including left axis deviation (9.48%, 44/464), sinus bradycardia (8.19%, 38/464), and T-wave abnormalities (7.76%, 36/464). A total of 10 types of electrocardiogram changes were detected in the control individuals, mainly including sinus arrhythmia (12.12%, 12/99), T-wave abnormalities (9.09%, 9/99), and sinus bradycardia (7.07%, 7/99). Echocardiography examination was conducted on 49 relatives of the cases and 365 villagers of the affected villages, respectively. A total of 12 types of echocardiography changes were detected in the relatives of the cases, mainly including tricuspid regurgitation (18.37%, 9/49), decreased right ventricular diastolic function (8.16%, 4/49), aortic regurgitation (6.12%, 3/49), and atrial septal defect (6.12%, 3/49). A total of 15 types of echocardiography changes were detected in the villagers of the affected villages, mainly including tricuspid regurgitation (8.77%, 32/365), aortic regurgitation (6.85%, 25/365), and decreased left ventricular diastolic function (6.58%, 24/365).Conclusion:There are many types of changes in electrocardiogram and echocardiography in the population of key areas of Yunnan sudden death.
