Brugada syndrome is a disease that disrupts the normal rhythm of the heart and is one of the rare causes of sudden cardiac arrest. This disorder manifests as ST segment elevation in the right precordial leads, causing ventricular arrhythmias. It can also cause syncope, convulsions, breathing disorders, or sudden death if it is not treated.

The patient was a 35-year-old man who was taken to the emergency room due to chest pain and loss of consciousness (fainting). In his electrocardiogram (ECG), Brugada syndrome-specific changes were observed, and the patient was transferred to the CCU.

Due to its low prevalence, this disease is usually not considered serious, and this may cause irreparable consequences for the patient, while it can be treated successfully with timely diagnosis.

 Vasovagal syncope is the most common type of syncope. Recurrent vasovagal syncope can have a profound effect on the patients’ quality of life. This study aims to predict vasovagal syncope based on interoceptive awareness and anxiety sensitivity of patients.

 This is an analytical and case-control study. The study population consists of patients with vasovagal syncope referred to Tehran Heart Center in 2021. Fifty patients with vasovagal syncope and 54 healthy individuals were selected by a purposive sampling method. Data collection tools included Multidimensional Assessment of Interoceptive Awareness and Anxiety Sensitivity Index. Data analysis was performed by logistic regression analysis in SPSS software, version 22. The significance level was set at 0.05.

 The Hosmer-Lemeshow test results (χ2=8.9, P=0.346) showed the good fit of the model. According to the results of logistic regression analysis, the coefficient of determination was -0.074 for the anxiety sensitivity and 0.018 for the interoceptive awareness.

 For patients with vasovagal syncope, the measures for increasing their interoceptive awareness and reducing anxiety sensitivity, can be helped for reducing their syncope.

Syncope is a sudden, transient and complete decline in the level of consciousness during which the patient cannot maintain his/her muscle tone and falls to the ground. Recovery is usually spontaneous and quick. Stimulants such as standing for a long time, hot bath and emotional stress are associated with this type of syncope. A significant percentage of cases of syncope occur while standing. Standing leads to the transfer of 500-800 ml of blood to the abdomen and organs. To deal with hypovolemia and reduce venous return, elastic compression stockings can be considered for treatment.

Long QT syndrome (LQTS) is a disorder in which electrical cardiac ventricular repolarization is impaired. It results in an increased risk of an irregular heartbeat which can result in palpitations, fainting, drowning, or sudden death. Long QT Syndrome may present as tonic-clonic seizure or a seizure-like disorder. By taking a superficial electrocardiogram (ECG) and proper diagnosis, Sudden death, one of the most important complications of Long QT syndrome can be easily prevented.

This is a prospective case-control study that was conducted in the emergency department of Taleghani Childrenchr('39')s Hospital of Gorgan University during 2017.Four hundred and eighty subjects in three groups (two cases and one control groups), were included in this study. These comprised as patients with afebrile convulsion (n: 160), patients with seizures associated with fever (n: 160), and the control group (patients who have been hospitalized for any reason other than seizure (n: 160)). Those with severe cerebral palsy, acute meningitis, prolonged loss of consciousness, severe disturbances of electrolytes and those who were taking drugs that affect the QT interval were excluded. Once admitted with a primary diagnosis of seizure, a 12 leads superficial ECG was performed.

 In the group of patients with febrile convulsion, 123 children were Low probability Long QT syndrome, 33 cases were Intermediate and 4 were high probability Long QT syndrome. Probability of Long QT syndrome in children with afebrile seizures showed that 112 children were in Low probability Long QT syndrome, 42 children in Intermediate and 6 children in High probability Long QT syndrome group. Comparison of Probability of Long QT syndrome among the three evaluated groups showed that children with afebrile seizure (48 children) and subsequently children with febrile seizure (37 children) were more in Intermediate and High categories than others. Only 11 children in the control group were in the Intermediate and High groups. Chi-square test results showed a significant difference with P<0.001.

 The results of this study show that in patients who present with seizure as the initial symptom, it is always mandatory to account Long QT syndrome into differential diagnosis. Doing a simple electrocardiogram makes it easy to distinguish two issues and prevent sudden death.

Transient loss of consciousness (TLOC) is one of the common causes for referral to hospital. Syncope and seizure can cause TLOC. Syncope and seizures can be the consequences of each other's. Their common features often lead to misdiagnosis. 

The purpose of this study was to present a patient (male, over 80 years), who received antiepileptic treatment for 6 years for seizure-related transient loss of consciousness.

Due to repeated episodes of suspected syncope, insertion of a dual-chamber PPM was done. After three years of follow-up, he did not report the occurence of the TLOC.

The frequency of the TLOC and its complications emphasize the importance of proper assessments, diagnosis, and treatment. A comprehensive history taking, exact examination, and para-clinical assessments can be very helpful for diagnosis. An incorrect diagnosis can cause economic, psychological, and social problems.

Cardiovascular Events occur at different ages for different reasons, One of the uncommon causes of sudden cardiac arrest that can be fatal in humans, is Brugada syndrome. The victims are often young men Appearance quite healthy. Its prevalence is high in Southeast Asia.The best treatment method in patients with ECG recognize But without a history of sudden cardiac death, Is that prognosis of clinical variables And ECG in patients with ECG Compatible with Brugada syndrome without previous history of cardiac arrest Effectively be analyzed.
The patient is a young man who in the early morning after waking up from sleep with Syncope and decreased level of consciousness And was brought to hospital emergency. On initial examination, patient had no pulse rate and electrocardiogram showed a straight line And bilateral pupillary dilation And had no reaction to light immediately (CPR) started after about 40 minutes rhythm of the patient was converted to sine and was transferred to the ICU . After transfer to the ICU and perform E.C.G characteristic changes Brugada syndrome was observed. In about a month hospitalization in ICU , and after tracheotomy and insertion(N.G Tube) patient was discharged and transferred to home and through a gastric tube feeding for a long time, he continued, And then with the help of those around him began oral feeding. Currently the patient is not able to mobility and activities and with the help of others continue to vegetative state life.

More than 5% of patients’ referred to Emergency Department (ED) and were suffering from syncope, which is the cause of 1-6% of inpatients. This study aims to study the etiology and outcome of syncope in patent referred to ED. This study investigated all syncope patients refer to ED of Imam Hossein Hospital for five months and the outcome was assessed for one-month. Data was recorded in questionnaire with patent’s file or history taking. Follow up was done one month later. T-test and chi-square test was used to analyze relationship between outcome and etiology. One hundred patients (66 male) with a mean age and standard deviation 67.7±17 years were assessed. Etiology in 35 (35%) patients was cardiac, 60 (60%) unknown, 4 (4%) cerebral and 1 (1%) was anemia. During follow up, 4 patients (2 men and 2 women) died. Etiology of death in these patients was cardiac and all of them were higher than 79 years old. Electrographical changes were observed in expired patients. Prevalence of recurrence was 4% and 9% of patients had surgery, which they were alive. ‍ Age higher than 70 years old with a cardiac etiology are the most important predictive factors in prognosis of patient and outcome of syncope.

Long QT syndromes (LQT) are genetic abnormalities of ventricular repo-larization، with an estimated incidence of about one per 10000 births. It is characterized by prolongation of the QT interval in electrocardiogram (EKG) and associated with a high risk for syncope and sudden death in patients. Type of this syndrome is association with congenital deafness. Our objective was to evaluate QT interval in children with congenital deafness. For 219 patients referred to Imam Khomeini Hospital audiometric clinic in 2011، questionnaire were completed. A total of 23 congenitally deaf children were incl-uded. All patients’ examinations were done by a pediatric cardiologist. Electrocardio-gram is conducted in all children (23 patients) with sever and deep congenital deafness. Then the QT interval was measured based on Bazett’s formula. Echocardiography was also performed in these children to assess left ventricular function and the presence of mitral valve prolapse. The overall patients were two hundred and nineteen children. A total of twenty three congenitally deaf children were included and electrocardiogram was obtained. Three children had obviously prolonged QTc (0. 48±0. 02) second. The median age of them was 6. 1±5 year، the median weight was 18±11. 3 kilogram and the median of QT interval was 0. 48±0. 02 second. The QT interval obtained 0. 48±0. 02 second. In the present study we found prolonged QT in congenital deafness، thus we recommend to evaluate the electrocardio-gram of children with congenital deafness.

IntroductionPatients with arrhythmogenic right ventricular cardiomyopathy have Ventricular Tachycardia (VT) and left bundle branch block contours with right-axis deviation and T-waves inversion in pericardial leads. Case reportPresenting case was a 28 years old man admitted with palpitation and syncope. The electrocardiography showed Ventricular tachycardia with left bundle branch block contour and T wave inversions in V1 to V6 and incomplete right bundle branch block and T wave inversions in V1 to V3. Echocardiography revealed right ventricular (RV) dilatation. RV function was abnormal, and aneurismal formation in free wall was seen in 3D echocardiography. ConclusionArrhythmogenic right ventricular cardiomyopathy remains as a primary diagnoses, in case of patients with ventricular tachycardia, left bundle branch block contour and T waves inversion in pericardial leads and without any history of ischemic heart disease,

Çongenital long-QT syndrome (LQTS) is an inherited disorder that presents with syncope، polymorphic ventricular tachycardia، torsade de pointes and sudden death. The incidence rate of LQTS is 1 to 2 per 100000 and mainly involves children and young individuals. Because of familial and genetic underling and predisposing factors for life threatening arrhythmias in patients، diagnosis and treatment are an important aspects in the management of this syndrome. Ïn this study LQTS is described in a 49 years old woman with syncope، ventricular fibrillation and torsade de pointes who was referred to the Fatemeh Zahra (S) teaching hospital and treated successfully
