Sudden death is a public health problem with more than 300,000 cases per year in USA and 40,000 cases per year in France. Moreover, despite all recent therapeutic improvements (therapeutic hypothermia, new techniques of resuscitation…), the prognosis remains drastically poor and less than 50% of the patients admitted alive at hospital will survive to the event at 1 year. Outside all medications and technical care to improve patient prognosis, a psychological evaluation looks also critical to detect the occurrence of a "post traumatic stress syndrome". In fact, along with the event severity, a variable period of amnesia related to coma may favor the occurrence of such a syndrome and psychological issues, which at the end may lead to impairment of patient quality of life. Previous studies have evaluated the impact of an intensive care unit diary on psychological distress in patients and relatives in the context of severe traumatisms. Such an evaluation has however never been done in the specific setting of sudden death and the frequency of this syndrome is unknown in this context. Aim The aim of the present study is to evaluate the impact of an intensive care unit diary on the occurrence of a "post traumatic stress syndrome" after a sudden death. Secondary objectives - To evaluate the frequency of the occurrence of a "post traumatic stress syndrome" and other psycho traumatic symptoms after sudden death - To evaluate the impact of an intensive care unit diary on the severity of this syndrome, psycho traumatic symptoms, and psychopathologic comorbidities - To evaluate the impact of the diary on psycho traumatic symptoms and their severity in patient's relatives - To evaluate the satisfaction of the patients and their relatives regarding medical cares in both groups (with and without diary) - Comparison of nurse diagnostic (psychological distress) and diagnostic made by dedicated personal with a specific formation in psychology - Qualitative evaluation of the diary - Evaluation of the paramedical feeling before and after the diary input in practice
Background: The wearable cardioverter defibrillator (WCD) is an established treatment option for patients at high risk for ventricular tachycardia / ventricular fibrillation (VT/VF), either in whom this risk may only be temporarily present, or in patients at high risk for sudden cardiac death (SCD) or after VT/VF in whom an implantable cardioverter defibrillator (ICD is currently not possible for other reasons (infection, recent MI <40days, recent PCI/CABG < 3months etc.). Methods: Comprehensive registry including all patients in Austria who received a WCD in 2010-2016.
Death rate in anesthesia is one of the most valuable methods to assess the safety of anesthesia practice among different types of patients. In this study, the investigators will follow the death among patients who underwent surgery under anesthesia whether regional or general over the next two years from 2016 to 2018.
Death rate in anesthesia is one of the most valuable methods to assess the safety of anesthesia practice among different types of patients. In the investigators study, the investigator will review the death rate in anesthesia whether regional or general over the past five years from 2010 to 2014, by examining the patients records from the hospital database.
Ventricular tachycardia is one of the commonest cause of sudden death in chronic chagas disease. As most ventricular tachycardias originate from scar in patients with heart disease, catheter ablation is an important step in patient treatment. Identification of fibrosis prior to ablation of sustained ventricular tachycardia (SVT) might reduce the time of anesthesia, procedure time, radiation exposure and possibly the risk of complications. Knowledge of arrhythmia circuit within scar allows planning strategies for each procedure. Condreanu et al. stablished that voltages inferior to 6.52 mV (unipolar) and 1.54mV (bipolar) are useful tools in detecting scar during electroanatomic mapping. Accuracy, however when compared to magnetic resonance imaging is limited due to difficulties in maintaining good contact between ablation catheter and ventricular wall. Contact force catheters might help increase accuracy of voltage mapping because they allow detection of poor contact areas. Although the threshold for identification of scar in ischemic and non ischemic patients during electroanatomical mapping is already known, this parameters still lacking for chronic chagasic individuals. A marked qualitative histological difference between these fibrous scars supports the hypothesis that voltage scar in chagasics might be different. Catheter ablation contact with endo and epicardial surface is an important issue when ablating arrhythmias. Conventional catheter ablation is not equipped with sensors capable of detecting degree of contact with the target. To our knowledge, the literature lacks information in regard to late lesions produced by a known contact force pressure "in vivo". The pattern of electrical activation in these patients and their relationship with local coronary veins for resynchronization likely to approach through the coronary sinus can be useful in defining chagasic that can benefit from resynchronization. 1. Compare endocardial and epicardial impedance and voltage using CARTO 3 with fibrosis on 3T MRI 2. Correlate areas of late activation within scar during activating mapping in sinus rhythm with different signal intensity in 3T MRI 3. Evaluate the influence of contact pressure during application of radiofrequency in making fibrosis analyzed 30 days after the procedure using a 3T MRI. 4. Assess the site of latest left ventricular activation in sinus rhythm and correlate with the coronary veins location
The aim of the present PPS3 study is (1) to assess the determinants of the regulation of heart rate and blood pressure variations and carotid properties (under different physiologic stimulations) and (2) to evaluate the respective contribution of heart rate, blood pressure variations and carotid properties to cardiovascular morbidity and mortality including sudden death during 10 years at least in healthy considered subjects.
This study will assess whether an implantable defibrillator will increase the likelihood of survival in patients who have had a heart attack, have abnormal test results from a 24 hour heart monitor, and who have low normal heart function.
Athletes with complex ventricular arrhythmias are potentially at risk of sudden death. The aim of the study is to investigate the relevance of ventricular tachyarrhythmias induced by an exercise test in a retrospectively evaluated athletic population.
