15例兒童心動過速性心肌病的臨床分析
[Abstract]:Objective: to investigate the clinical features, diagnosis, treatment and prognosis of cardiac tachycardia (Tachycardia-induced cardiomyopathy,TIC), and compare it with (Dilated Cardiomyopathy, DCM) of primary dilated cardiomyopathy to improve the understanding and guide the diagnosis and treatment of TIC. Methods: 374 cases of arrhythmia and 53 cases of primary dilated cardiomyopathy were collected from January 2007 to December 2013 in our hospital. Among them, 15 cases were in accordance with tachycardia cardiomyopathy and 24 cases were in accordance with dilated cardiomyopathy with tachycardia. The general data, clinical manifestations, cardiac function, chest radiographs, electrocardiogram (ECG) or 24 hour ambulatory electrocardiogram (ECG), echocardiography, treatment, curative effect and prognosis were retrospectively analyzed and compared between the two groups. Results the age of the two groups was 2.7 鹵3.3 years old and 7.9 鹵4.0 years old, respectively. There was significant difference between the two groups (t = 4.47, P 0.01), but there was no significant difference in the sex, the course of disease, the modified Ross score and the first hospitalization time between the two groups (P0.05). The clinical manifestations of the two groups were similar. They all showed shortness of breath, fatigue, sweating, palpitations, paleness, dizziness, and so on. Most of the children had symptoms of cough, fever, vomiting, abdominal pain, etc. The heart rate of the two groups was 189 鹵26.4 times / min 135.4 鹵35.8 times / min respectively, and the difference between the two groups was statistically significant (t = 5.97, P0.01). In TIC group, atrial tachycardia was predominant (8 cases, 53.3%), while in DCM group, sinus tachycardia accompanied with frequent ventricular premature beat or atrial premature beat was the main factor (10 cases, 41.6%). Before hospitalization, LVEF,LVFS in TIC group was significantly higher than that in DCM group (P0.05), and the difference was statistically significant. The improved Ross scores were significantly improved compared with those before treatment (P0.05), and the difference was not significant (P0.05). After discharge, 14 (100%) children in the DCM group were found to have normal cardiac function and 10 (71.4%) had normal cardiac function, while 7 cases (41.2%) in the DCM group had lost their visit and 7 cases (41.2%) had died. Of the remaining 10 cases, 3 cases (30.0%) had normal cardiac function and 10 cases (100%) had significant left ventricular enlargement. The difference between the two groups was statistically significant (P0.05). Conclusion: there are many similarities between TIC and DCM in clinical manifestations, echocardiography, chest radiography and electrocardiogram, which are easy to be confused and sometimes difficult to distinguish. For the children with tachycardia, cardiac insufficiency and cardiac enlargement, we should consider TIC, but at the same time, we must pay attention to the differential diagnosis of DCM. TIC is usually acute, and arrhythmias are mainly frequent or persistent atrial tachycardia. Before treatment, the decrease of cardiac function and the degree of cardiac enlargement were not as good as those given by DCM,. After the treatment of controlling ventricular rate and heart failure, the cardiac function could return to normal in part or even completely, and the prognosis was obviously better than that of DCM..
