	691	Analysis of clockwise rotation electrocardiograms of 86 patients with pulmonary tuberculosis

		Objective To explore the diagnostic value of clockwise rotation electrocardiogram(ECG) for right ventricular hypertrophy in patients with pulmonary tuberculosis. MethodsEchocardiogram was performed on patients with pulmonary tuberculosis and clockwise rotation ECG so as to divide them into right ventricularhypertrophy group and nonrightventricularhypertrophy group. Besides clockwise rotation, compare the differences of other ECG changes between the two groups.ResultsAmong 86 cases, it indicated by echocardiogram that 40 cases(46.5%) fell in the right ventricular hypertrophy group while 46(53.5%) in the other. Compared with patients in nonrightventricularhypertrophy group, the other group showed higher incidence rate of other concomitant ECG changes, such as right axis deviation, nodal tachycardia, ST-T change as well as high and sharp P wave. In addition, the differences possessed statistical significance（P＜0.05）. ConclusionClockwise rotation ECG of patients with pulmonary tuberculosis have some value in the diagnosis of right ventricular hypertrophy. It strongly indicates the chance of right ventricular hypertrophy, especially when right axis deviation, nodal tachycardia, ST-T change as well as high and sharp P wave appear.

	694	Clinical analysis of fragmented QRS complex in dilated cardiomyopathy patients

		Objective To explore the clinical value of fragmented QRS complex (fQRS) in patients with dilated cardiomyopathy(DCM).Methods Retrospectively analyse 112 patients suitable for DCM diagnostic criteria. According to the existence of fQRS complex in 12 lead ECG and duration of QRS complex, divide them into fQRS group, wideQRS (wQRS) group and non fragmentedQRS (nonfQRS) group, and then compare the incidence rate of fQRS between DCM patients and the control group. In addition, the incidence rates of the decrease of left ventricular ejection fraction(LVEF) and ventricular arrhythmia and cardiogenic shock and cardiac death of patients with fQRS, wQRS and nonfQRS were also compared.Results TThe incidence rate of fQRS in the observation group was significantly higher than that of control group(P<0.01). Among the observation group, the incidence rates of fQRS and wQRS were noticeably higher than that of nonfQRS group(P<0.05). In aspects of the incidence rates of the decrease of LVEF and ventricular arrhythmia and cardiac death, those two groups were also higher than nonfQRS group(P<0.05).ConclusionBesides other evidences to diagnose DCM, fQRS could serve as a new indicator for the diagnosis of DCM, which can also be considered as one of the early indicators for DCM high risk population.

	697	A study about dispersion degree of repolarization in ventricular tachycardia patients with J wave

		Objective To study the ECG changes of dispersion indexes of repolarization of ventricular tachycardia(VT) patients with J wave, such as QTd, Tp-e and Tp-e/QT and explore the reasons. Methods For the patients whose J waves were recorded by ECG, divide them into two groups according to the existence of the attack of VT and compare the dispersion indexes of repolarization in ECG. Twentytwo cases with VT and J wave were enrolled, with 12 males and 10 females, at an average age of (52.3±12.3) years old. In the control group, select 56 cases whose ages and genders were matched, with 31 males and 25 females, at an average age of (551.8±10.1) years old. All of the cases enrolled were undergone synchronized 12 lead ECG, with QTd and Tp-e interval measured and the ratio of Tp-e/QT calculated. ResultsCompared with the control group, the value of Tpe increased in the observation group［(89.6 ± 15.1)ms vs. (65.3 ± 14.2) ms, P < 0.001］, and so did the ratio of Tp-e/QT（0.22 ± 0.05 vs. 0.16 ± 0.04, P < 0.001）, and the differences were statistically significant. However, between the two groups, the difference of QTd showd no statistical significance［(41.1±3.6) ms vs. (38.7±3.9) ms,P>0.05)］.ConclusionFor VT patients with J wave, both of the increase of Tpe and Tp-e/QT reflects the increase of dispersion degree of transmural repolarization which indicates big chance of attack of VT arrhythmia.

	699	Analysis of the correlation between changes of Sokolow index and Tv5/R with left ventricular hypertrophy

		ObjectiveTo discuss the quantitative expression of the changes of ECG Sokolow index (R_v5+S_v1) and T_v5/R with left ventricular hypertrophy(LVH). MethodsRetrospectively analyze ECG baseline and its changes after one year, and record the changes of ECG voltage as well as left ventricular mass index (LVMI) of 80 patients with hypertension.With the help of multiple linear regression analysis, the correlation between the changes of ECG Sokolow index and T_v5/R with those of LVMI was analyzed.Results For patients with hypertension, the changes of LVMI showed a significant linear correlation with the changes of ECG Sokolow index and T_v5/R. An empirical formula was derived which was based on statistical data. ConclusionThe changes of ECG Sokolow index and T_v5/R predict the corresponding changes of LVMI. It therefore offers a method economical and convenient enough to be applied in the postoperative followup of patients with LVH and the guidance of clinical treatment.

	702	Clinical observation of patients with acute anterior myocardial infarction and ST segment elevation in lead V4R

		Objective To investigate the clinical situations and prognosis of patients with acute anterior myocardial infarction and ST segment elevation(STE) in lead V_4R.MethodsRetrospectively select 132 cases of patients with the disease, among which there were 49 cases in V_4R-STE group and 83 in nonV_4R-STE group. Separately Observe the ranges of STE and increase of myocardial enzymes by routine 12 lead electrocardiogram(ECG) as well as left ventricular ejection fraction and ventricular wall motion by echocardiogram. Cardiovascular events include attacks of congestive heart failure or malignant arrhythmia(such like multifocal ventricular premature beats, ventricular tachycardia and ventricular fibrillation) and the happens of death. In addition, take a close observation on coronary arteriongraphy of patients in the two groups. ResultsBetween the two groups, compare the range of STE on 12 lead ECG and left ventricular ejection fraction and segmental abnormality incidence of ventricular wall motion, which resulted in statistically insignificant differences(P>0.05). In the meantime, for 49 cases in the V_4RSTE group, the range of myocardial enzymes as well as the incidence rates of cardiovascular events and multivessel diseases(P<0.01). Conclusion It needs to take 18 lead ECG for patients with acute anterior myocardial infarction with SET in order to evaluate recovery of heart and prognosis more accurately.

	708	WPW syndrome diagnosis and treatment principles

		Pre-excitation syndrome is an electrocardiographic pattern in which all or part of the ventricular muscles can be activated sooner than normal due to atrial activation by accessory pathway. The existence of the bundle of Kent contributes to formation of the classic preexcitation syndrome (the socalled Wolff Parkinson White syndrome, WPW syndrome), with an incidence rate of about 0.1‰-0.3‰ and 7%-20% of these patients are complicated with other congenital heart diseases(such as Ebstein’s anomaly). WPW syndrome can be categoried by manifest pre-excitation, intermittent pre-excitation, incomplete latent pre-excitation, latent pre-excitation and concealed pre-excitation. Tachyarrhythmia related to WPW syndrome includes atrioventricular reentrant tachycardia and atrial ectopic activation down the ventricle through accessory pathway.The existence of pre-excitation could probably make it harder for ECG diagnosis of some diseases. For example, pre-excitation is always exactly like or conceals myocardial infarction or bundle branch block and so on. Therefore, elimination of δ wave could help in differential diagnosis.Generally, pre-excitation syndrome has a good prognosis and radiofrequency ablation has become a preferred treatment.

	716	The methods and techniques of esophageal cardiac electrophysiology to induce and terminate tachycardia

		Reentrant tachycardia is a clinically common cardiovascular disease. Since its attack begins and ends abruptly, sometimes routine electrocardiogram could not record the electrocardiogram timely in case of attack, and it’s also difficult to identify the specific nature of tachycardia accurately, thus treatment might be affected. Esophageal cardiac electrophysiology could not only induce tachycardia, identify the nature of tachycardia, but also terminate it safely, effectively and quickly.

	742	Radiofrequency catheter ablation of arrhythmias guided by magnetic navigation system

		Magnetic navigation system (MNS) is the only tool for cardiac interventional diagnosis and treatment based on magnetic navigation now in the world.The methodology of interventional therapy in cardiovascular diseases has been completely changed by MNS, which has been widely applied in interventional treatments of arrhythmias and coronary heart disease in abroad and yet seldom used in China.The paper will make a review mainly on radiofrequency catheter ablation of arrhythmia guided by MNS on the setting of composition, working mechanisms and procedures. Arrhythmias are including supraventricular arrhythmia, ventricular arrhythmia and ones due to congenital heart disease.

	748	Ventricular gradient reevaluation in the way of evidencebased medicine

		Objective The ventricular gradient(VG) represents the metabolic abnormalities of myocardial repolarization itself and the observation of VG contributes to the identification of primary and secondary T wave changes, which provides a new reference index for clinical diagnosis of coronary heart diseases and primary electrocardiorelated diseases.VGH bears a good capacity of predicting ventricular arrhythmias for ICDimplanted patients. There lies a strong connection between VGx and the diagnosis of pulmonary artery hypertension and prediction of death rate.TCRT is significantly positive correlated with forward mortality of patients with myocardial infarction.

	756	The necessity of sinus bradycardia patients taking dynamic electrocardiogram examination

		ObjectiveTo acquire a knowledge of various kinds of circumstances when sinus bradycardia patients (the average heart rate＜55 bpm) are taking dynamic electrocardiogram (ECG) examination.Methods Select 100 cases of outpatients and inpatients from January 2012 to January 2013 who were diagnosed by routine ECG examination with sinus bradycardia.Results When obvious sinus bradycardia attacks and long RR interval longer than 2.0 seconds appears, the usual causes include coronary heart disease, hypertension and myocardial infarction. From primary to secondary, the reasons for ECG changes of long RR interval are as follows that obvious sinus bradycardia complicated with arrhythmia accout for 43%(43/100), nonconducted atrial extrasystoles accout for 21%(21/100), Ⅱ° atrioventricular block 17%(17/100), Ⅱ° sinoatrial block 10%(10/100) and sinus arrest 9%(9/100).Conclusion The dynamic ECG proves to be safe and effective in the examination of obvious sinus bradycardia, causes analysis of long RR interval as well as diagnosis of a variety of ECG changes, which help to promote the diagnostic accuracy and cure rate clinically.

	762	The exploratory study on the standardized training system for refresher physicians

		It is significant to improve the training system of clinicians (including ECG physicians) in roder to promote the grassroots clinical level and deepen the medical system reform. However, at present, domestic continuing education system is far from perfect, lacking the standardization while the majority of teaching hospitals doesn’t pay enough attention on the education, which badly affect the effect of training. In recent years, active exploration has been carried out in the aspect of standardized continuing education; Systematic and detailed clinical traing plans have been erected; The tutorial system for refresher physicians has been tried out, attaching more attention upon the developments of research thinking and paper writing skills as well as emphasizing the traing of medical ethics. All of the above exploration has successfully achieved great effect.
