قمنا في مشفى الأسد الجامعي باللاذقية و خلال الفترة الممتدة من شباط 2012 و حتى شباط 2013 بدراسة عينة عشوائية مكونة من 97 مريضاً (ذكوراً و إناثاً) موزعين على ثلاث مجموعات: المجموعة الأولى و تضم 16 مريضاً لديهم توسع أذينة يسرى بدون رجفان أذيني، المجموعة الثانية و تضم 70 مريضاً لديهم توسع أذينة يسرى مع رجفان أذيني، المجموعة الثالثة و تضم 11 مريضاً لديهم رجفان أذيني بدون توسع أذينة يسرى. تم في هذه الدراسة قياس مشعر حجم الأذينة اليسرى (LAVI) باستخدام الايكو دوبلر القلبي من خلال طريقة سيمبسون، و ذلك لتقييم علاقته بحدوث الرجفان الأذيني. حيث وجد في هذه الدراسة أن ثلاثة مرضى من المجموعة الأولى (16مريضاً) أي ما يقارب حوالي 18.75% تطور لديهم رجفان أذيني بعد سنة من المتابعة أي أن توسع الأذينة اليسرى يخدم كمتنبئ لحدوث الرجفان الأذيني. كما لوحظ أيضا استمرار الرجفان الأذيني و ديمومته مع حدوث زيادة في حجم الأذينة اليسرى بعد مرور سنة من متابعة مرضى المجموعة الثانية. بالمقابل فإن خمسة مرضى من المجموعة الثالثة (11 مريضاً) حدث لديهم زيادة في مشعر حجم الأذينة اليسرى في نهاية فترة الدراسة أي بنسبة قدرها 45.45% (P<0.001)، و عليه فإن الرجفان الأذيني يمكن أن يسبب توسع أذينة يسرى. و على الرغم من أن توسع الأذينة اليسرى يمكن أن يسبب رجفاناً أذينياً، و العكس بالعكس حسب ما توصلنا إليه وفق نتائج بحثنا، فإن هذه الدراسة أظهرت أيضاً احتمال وجود عوامل أخرى مؤهبة تلعب دوراً في حدوث و نشوء الرجفان الأذيني.
A study was conducted in Al-Assad University Hospital in Lattakia during the period February 2012 and February 2013 the study included a random sample of 97 patients (males and females) divided into three groups: the first group consisted of 16 patients with left atrial enlargement with no atrial fibrillation, the second group included 70 patients who had left atrial enlargement with atrial fibrillation, and the third group of 11 patients had atrial fibrillation with no left atrial enlargement. In the study the ECHO Doppler was used for measuring left atrial volume index (LAVI) through the Simpson method, this is in order to assess the role and relationship with the occurrence of atrial fibrillation. It was found out that three patients out of (16) from the first group about 18.75% developed an atrial fibrillation after one year of follow-up, which means that the left atrial enlargement gave a predication of the occurrence of atrial fibrillation. The continuation of atrial fibrillation was also noticed together with its lifetime with an increase in the size of left atrial after one year of following-up the patients of the second group. 3 out of (11) patients from the third group had an increase in the left atrial volume index at the end of the study 45.45% (P<0.001), Accordingly the atrial fibrillation could cause left atrial enlargement.Even though the left atrial enlargement may cause atrial fibrillation and vice versa according to thisstudy, the study shows the possibilities of existence of other variable factors related to atrial fibrillation whichplay a role in the occurrence.

Surgical ablation of atrial fibrillation (AF) has been gaining ground as the
preferred method of treatment of this potentially lethal arrhythmia
affecting 1/3-1/2 of patients with mitral valve diseases.
It is specially suited for patients undergoi
ng an operative procedure.
Between Dec 12,2002 and Dec 29,2003 ,fifty five operative patients with
chronic AF were subjected to AF ablation with microwave energy at
Damascus University Cardiovascular Surgical Center .
Thirty five patients were female; age ranged between 20 and 72 years.
All of them had chronic AF.
Cardiogenic embolism can be identified in at least 15% of ischemic stroke patients,
left atrial appendage is believed to be the place where thrombi is performed, then goes to
systemic circulation causing embolic accident .
In this search we study
the function of left atrial appendage by pulse Doppler within
the proximal third of the appendage in patients with ischemic stroke. Thrombus was
defined as a discrete echocardiographically dens mass within the body of atrium or the
appendage, with a different echocardiographically density than the adjacent endothelium .
Spontaneous echo contrast was defined as high density flow due to low flow
condition , which remains stable with changes in gain setting .
In conclusion , the velocities which recorded in patients with ischemic stroke were
lower in comparison with other patients , and it was significant lower in patients with
spontaneous echo contrast or atrial fibrillation .
A-60 years old woman, did cardiac consulting for hypertension Interrogation: The patient is asymptomatic she has the following cardiac risk factors Smoking (1) Packet / day for 40 years and arterial hypertension for 20 years ago , uncontrolled she ha
s not surgical or medicals antecedents Cardiovascular examination: BP: 14,5\90, pulse : 80\ M, No murmurs no additional voices ,peripheral pulse are palpable, no edema , not congestion jugular . Twelve-lead electrocardiography showed sinus rhythm,there are not troubles of repolarization, no of conduction Chest radiography showed normal cardiac silhouette, blood tests are normals Echocardiography throw chest : showed the presence a mass in the left atrium, measuring 4 x 3.5 cm lobed ,smooth heterogeneous, attached to the atrial septum , it has broad base extends from the fossa ovalis to the roof of the left atrium beside superior vena cava to the right side Echodppler throw esophagi does not appear more data, but it showed absence of anthor tumors in other cardiac cavities Cardiac catheterization: showed the presence of multiple aneurysms on the coronary arteries with stenosis of 50% on the first segment of the anterior descending coronary artery(LAD) The patient has been transferred to the Department of Cardiac Surgery, where the tumor was removed successfully and Histopathology showed that it is an aterial myxoma ( benign tumor)
This study investigates the relationship between the financial
development and the economic growth in Syria during the period
(1980-2010). The financial development was measured by the
credit granted to the private sector and the broad money M2
whereas the economic growth was measured by the real gross
domestic product per capita.
This paper tries to examine the relationship between analogy and the grammatical
rule. Analogy is one of the basic principles and bases of Arabic grammar during times of
rule formation and judging it. Linguists were divided in their attitude to ana
logy, with
some supporting it and others against it. Grammarians were more inclined toward analogy
than compilers, because grammarians’ research was based on the existing similarity
between words, phrases, and style used in speech reported by tellers of what had been said
by the Arabs. They based their rules and origins of analogy on that similarity. Analogists
transliterated some foreign terms, Arabized, and derived new words out of them in a
manner similar to that done with Arabic terms. However, some grammarians went very far
in their excessive use of analogy to the extent that it becomes far removed from linguistic
reality to be a form riddle and guessing, leading to reaction against analogy then against
grammar. Analogy became an end in itself; it overlooked its original purpose; was then
manifested in rule formation of words said spontaneously.
