| dc.description.abstract | By increase in average age of society, incidence of disease related to aging increase in people. One of the most important diseases in this field is coronary artery disease which needs for coronary operation in these patients as one of the therapeutic methods. atrial fibrillation was recognized as a more common arrythmia after coronary artery bypass surgery. Incidence of this rhythm after operation leads to increase in incidence of CVA and thrombo embolic events and soon after increase in mortality , morbidity ,hospitalization and cost of medical care. post operative AF rhythm increases patients mortality up to 29%. Also keeping sinus rhythm has advantages such as improve in quality of life, improve in heart performance in CHF patients, decrease in risk of thromboembolism, and decrease in side effects resulted from long term anti coagulation. According to issues above, diagnoses of high risk patients and treat preventively with anti arrhythmic agents may be prevent these complications. One method that can predict this arrhythmia is evaluation of electromechanical delay of atrial function with simultaneous ECG and Doppler and TDI study of mitral valve. In this study all CABG candidate patients with basic sinus rhythm were examined before surgery by echocardiography and then monitored for 72 hours and if the AF rhythm occur ,documented in patients shit .after that ,patients information were annalized by SPSS 15 soft ware. 404 patients were introduced in this study.mean age was 60 years.228 patients were men and 176 were women.65 patients were experience AF rhythm in 3 days after surgery.In present study there was statistically significant relationship between AF rhythm in one hand and, LAVI, right ventricle dysfunction, urgency of surgery, mitral ring size , older age ,on pump surgery and lower EF on the other hand. there were no statistically significant relationship between AF rhythm in one hand and interval between P-wave start in surface ECG and A-wave start in Doppler examination of mitral flow and A`wave peak and start in TDI study of septal leaflet of mitral valve.,
هدف از این مطالعه، بررسی ارتباط فاصله زمانی شروع موج P در الکتروکاردیوگرام سطحی تا شروع موج A در مطالعه داپلر فلوی دریچه میترال با بروز فیبریلاسیون دهلیزی در72 ساعت اول بعد ازعمل جراحی بای پس عروق کرونری می باشد.در این طرح بیماران کاندید ای جراحی CABG که ریتم پایه سینوسی داشتند تحت بررسی با اکوکاردیوگرافی قبل از عمل قرار گرفته و سپس بعد از انجام جراحی به مدت 72 ساعت تحت مونیتورینگ مداوم قرار گرفته و در صورت بروز ریتم AF در پرونده بیمار ثبت شد.پس از جمع آوری اطلاعات تجزیه و تحلیل آماری از طریق15 SPSS صورت گرفت.جمعا 404 بیمار در مطالعه شرکت کردند.میانگین سنی بیماران 60 سال بود. 228 بیمار مذکر و 176 بیمار مونث بودند .65 بیمار در 3 روز اول بعد از عمل ریتم AF پیدا کردند.ریتم AF با متغیرهایی از جمله LAVI ،نارسایی RV،اورژانسی بودن عمل،بزرگی رینگ میترال،سن بالا ، جراحی on pump و EF پایین از نظر آماری رابطه معنی داری داشت اما با فاصله زمانی شروع موج P تا شروع موج A در بررسی داپلر دریچه میترال و شروع و قله موج A در بررسی TDI لت سپتال دریچه میترال ارتباط معناداری نداشت | |
