| Objective: Chronic heart failure (chronic heart failure, CHF) patients always suddencardiac death (sudden cardiac death, SCD) is a high-fat group, how can early detection of potential high-risk elderly patients with SCD, and to make reasonable and effective treatment measures Clinical research has always been the most popular topic.Heart rate turbulence (heart rate turbulance, HRT) has been the phenomenon of theautonomic nervous system is a fresh evaluation indicators (autonomic Nervous System, ANS) function, which has a very important significance in the clinical value andscientific risk assessment and prediction of SCD. The current definitions of heart rate turbulence (HRT) are separate rom before the emergence and a contraction (ventricular premature complex, VPC) after sinus cycle physiological self-regulation and change, this phenomenon is reflected in the human autonomic nervous system functionproperly when performance of early heart rate followed by a short time and the heart rate slows down, when the performance of a room early after HRT weaken or disappear when the autonomic nervous system does not function properly or damaged.The main subject of study among elderly patients with chronic heart failure (CHF)patients with heart rate turbulence (HRT) and its variation with TCM syndrome differentiation, cardiac function, left ventricular end-diastolic inside by (LVEDD) and left ventricular ejection fraction (LVEF) of association, and discuss heart rate turbulence(HRT) if there is a change phenomenon guidance whether chronic heart failure (CHF) in patients TCM research value and type of heart rate turbulence (HRT) phenomenon prognosis in elderly patients with chronic heart failure and risk stratificationof the presence and influence.Methods: First Affiliated Hospital of Henan College of outpatient and inpatient metthe inclusion criteria with previous history of coronary artery disease and chronic heart failure patients with64cases of premature ventricular contractions combined,and24-hour ambulatory electrocardiogram (dynamic electrocardiogram, DCG) Determinati on of compliance with the requirements HRT, as well as the age and sex-matchedhealthy subjects in20cases. NYHA classification criteria for the seven cases of grade Ⅰ7cases,, Ⅱ7cases, Ⅲ32cases,Ⅳ18cases. Chronic HF group40males and24females, healthy control group,10males and10females, the average age ofwithin the range of60to75years old. Are used by the U.S. GE’s12lead ECGmachine ECG changes detected24hours, respectively, after the computer analysis software to calculate the initial shock (TO) and turbulence slope (TS) values, while using the U.S. company GE echocardiographic diagnostic measurements LVED, LVEFvalues. And monitor the patient’s routine blood biochemical parameters and BNP.Results:1No heart failure patients and healthy control groups in age, gender and basic pathological aspects of differences, however, heart rate turbulence (HRT) contrast between heart failure patients and healthy control group were significantly different,heart failure group The initial shock (TO) values than healthy control group was significantly higher than a lot of turbulence slope failure group (TS) values significantly lower than the control group a lot, indicating heart failure group compared to thecontrol group was significantly decreased or disappeared HRT.2the heart failure and the control group in the LVEF values and the LVEDD values, there have many significant differents in BNP values.3.NYHA cardiac function increments, the greater the value of HRT TO and TS changes. The TO and heart failure in cardiace function is directly proportional relationship; TS values and cardiac function showed a negative relationship between the percentage of growth.4. Results of heart failure syndrome differentiation type of display, heart and lung qi4cases, Qi8cases,7cases of heart deficiency, blood stasis type12cases,19cases of generic yang water, phlegm11cases of lung resistance, yin yang dried off3cases of patients with symptoms of TCM typing aggravated waning phenomenon HRT patients, cardiac function gradually increased.Conclusion: heart failure heart rate turbulence becomes smaller, embodied rise in TOand TS decreased. Heart rate turbulence (HRT) couid be used as a cardiac functionin patients with chronic heart failure and reflect the severity of heart failure indicators, HRT and cardiac function, LVEF, LVEDD, BNP and other aspects associated with sex, TCM HRT with chronic heart failure type also have many relevance, HRT may reflect cardiac function in patients with heart failure and heart damage to autonomic function. |
