  Cardiac resynchronization therapy(CRT) has become type Ⅰ indication of chronic heart failure complicated by ventricular asynchronism, and thus the number of CRT pacing electrocardiograms(ECGs) increases significantly. In the analysis and diagnosis of CRT pacing ECG, it is mandatory to master the following characteristics: (i) ECG features when left and right ventricle is made pacing  alone; (ii) ECG features at atrialventricular and ventricular sequential pacing during sinus rhythm; (iii) features of CRT pacing ECG during ectopic rhythm; (iv) special functions of CRT pacemaker.

  The appearance of late sodium current: from sympathetic T wave to Takotsubo syndrome

  JIA Zhong-Wei

  Sympathetic T wave is a kind of cardiac electrophysiological abnormality related to sympathetic stress. Besides cardiac electrophysiological abnormalities, Takotsubo syndrome includes cardiac mechanical dysfunction. They share the same pathogenesis including sympathetic excitation, late sodium currentⅠNaL) and electrophysiological abnormalities of myocardial cell mediated by calmodulin, etc. However, they may be different clinical manifestations of the same disease.

  Clinical application of improved RR interval scatterplot and its reversal technique in diagnosing typical sick sinus syndrome

  XIANG Li-Ming, LIU Ming

  In clinical practice, we construct RR interval scatterplot of patients with typical sick sinus syndrome(SSS) with Lorenz scatterplot mapping system included in AECG analysis software. However, in this way, the graphic changes of long interval(＞2 s) can not be shown in the scatterplot. The upper limit of coordinates in Lorenz scatterplot mapping system is reseted from original 2 s to 4 s. This paper compares the similarities and differences of RR interval scatterplots in the two upper limits of coordinates, and makes confirmation with reversal analysis technique. Our study revealed that attractors were more than before by 1 to 4 in the improved RR interval scatterplot which can show complete scatterplot graphs. However, the scatterplot in a coordinate upper limit of 2 s can only display local features. Therefore, it is not appropriate to make auxiliary diagnosis of SSS with the RR interval scatterplot in a coordinate upper limit of 2 s. Its improved version taking 4 s as the upper limit of coordinates can reflect the characteristics of SSS scatterplot more completely and more effectively.

  Objective:To summarize and analyze the distribution characteristics of research literatures on Brugada syndrome(BrS). Methods:With the retrieving tool of GoPubMed, we retrieved BrSrelated literatures included by Medline from January 1, 1992 to December 31, 2015 and made bibliometric analysis on the distribution characteristics of published year， area, journal, research theme, etc. ]Results:A total of 2 220 papers were retrieved. The number of research literatures gradually increased after 1998 and reached relative peak value in recent three years. The leading countries in BrS literature quantity were the United States(386 papers, 17.39%), Japan(353 papers, 15.90%) and France (133 papers, 5.99%) successively, and China ranked the 11th(53 papers, 2.39%). The top three literatureoutput cities were Amsterdam in Holland(80 papers), Tokyo in Japan(70 papers) and Utica in America(58 papers). Beijing was the leading literatureoutput city in China, ranking the 36th(13 papers) in the world, and it was followed by Nanjing and Guangzhou which were tied for the 43rd place(7 papers) globally. The first three journals were Heart Rhythm(144 articles), Journal of Cardiovascular Electrophysiology(143 articles) and Pacing and Clinical Electrophysiology(90 articles), which published 16.98% of all the BrSrelated articles. Themes of BrS research mainly focused on genes, electrocardiographic manifestations, ventricular arrhythmias, sudden death, ICD implantation and so on. Conclusion:BrS, related studies mainly concentrate in developed countries. Chinese researchers should strive to improve the overall quality and quantity of BrS research.
