Filter by:The Physiologic Pacing Registry is a prospective, observational, multi-center registry performed to gain a broader understanding of 1) physiologic pacing implant and follow-up workflows, including pacing and sensing measurements and 2) the clinical utility in creating a 3-dimensional electro-anatomical map of cardiac structures prior to physiologic pacing device implants based on the clinical site's routine care.
Study hypothesis: cardiac autonomic dysfunction may affect vaso vagal syncope recurrences in type 2 patients with diabetes vs. patients without diabetes. Background: vaso vagal syncope and its recurrences may be due to alterations in autonomic system function, that may be more frequent in diabetics. Heart rate variability (HRV) is a valid test to study sympathetic and vaso vagal tone dysfunction. However, in this study authors investigated the correlation between HRV alterations and diabetes in a population of patients affected by syncope, and classified as vaso vagal syncope by Head Up Tilt Test (HUT) exam. Secondly, authors assessed these alterations as causes of vaso vagal syncope recurring at 12 months of follow up in type 2 patients with diabetes under sodium-glucose transporter 2 inhibitors (SGLT2-inhibitors) vs. other hypoglycemic drugs .. Materials and Methods: In a multicenter study authors studied T2DM patients under SGLT2-I therapy (n 426) vs. those that did not receive the SGLT2-I therapy (n 2195), and affectede by vaso vagal syncope. All enrolled patients were in stable sinus rate before to perform ECG Holter, and the Head Up Tilt Test (HUT). However, before to perform the HUT all patients performed a 24 hours ECG Holter, to asses sinus rhythm , heart rate, and HRV. Then, these patients performed a 123I-metaiodobenzylguanidine (123I-MIBG) myocardial scintigraphy to assess cardiac autonomic dysfunction. Moreover, authors performed a propensity score matching (PSM) analysis to evaluate 160 SGLT2-I users vs. 160 Non-SGLT2-I users' patients.
The aim of this project is to better understand the experiences of people who have idiopathic drop attacks. These falls have no identified medical cause but can cause people injuries such as bruising, facial injuries and, in some cases, broken bones. It can also make them worry about having more falls, and the pain and embarrassment this would cause, and stop them from going out. There has been very little research in this area and there are currently no treatments. In this study, ten people who experience idiopathic drop attacks will be interviewed at an outpatient clinic to understand more about them and the falls. They will be asked in particular about the period of time around when they started having the falls and whether there are aware of any triggers. Participants will also be asked to write accounts of these drop attacks, after they have happened, for a period of eight weeks. They will be asked to describe what they were thinking and feeling, and how they felt in themselves before and after the fall. This information will allow the researcher to look at common experiences that people who experience these falls have. This understanding could help to identify whether a psychological approach to treatment could help individuals to manage and cope with this condition.
This is a randomized controlled open-label trial. During the study, adolescents scheduled to receive at least one intramuscular (IM) vaccine will receive either Buzzy®, Music, or Buzzy® and Music intervention(s) in addition to standard care to evaluate the feasibility and acceptability of these interventions prior to being used in a larger study to assess the effectiveness of the interventions in preventing post-vaccination presyncope and syncope. Feasibility will be assessed according to study staff ability to successfully administer the protocol specified clinic-based interventions and per both study staff and healthcare provider responses to written feasibility assessments. Acceptability will be assessed according to the participant's self-report. In addition, baseline needle phobia and anxiety, post-vaccination pain and presyncope symptoms, and pre- and post- vaccination state anxiety will be assessed per participant written self-report to standardized survey questions.
Investigators propose an intervention trial of a comprehensive education and treatment bundle designed to reduce morbidity and mortality associated with heat-related illness for low resource settings. Two set of interventions will be developed each for emergency department and for community/home. These interventions will be developed by an internal expert group and will be customized and implemented at the home and emergency department (ED) levels, will include evidence-based educational training guidelines for ED health providers as well as educational messages targeting home and community in Karachi, Pakistan.
Syncope is a rapid onset, transient, loss of consciousness with a short duration. This symptom has been reported to be a specific presentation of patients with pulmonary embolism. However, the prevalence of pulmonary embolism in patients with syncope remains debated. This prospective cohort study will recruit patients presenting to the emergency department with a syncope, who will systematically undergo formal workup for pulmonary embolism. The main objective of this study is to assess the prevalence of pulmonary embolism in ED patients with syncope
Syncope, or transient loss of consciousness/fainting, is a common emergency department (ED) complaint responsible for over 1 million ED visits yearly. Potential causes include benign conditions such as dehydration or vaso-vagal syncope. Rarely, syncope is the result of serious cardiac conditions. In older patients without a clear cause of syncope hospital admission is frequently initiated at very low risk thresholds, though there is little evidence that these admissions improve patient outcomes. These decisions are often made without significant patient input or discussion of reasonable alternatives. In this situation, a patient's values, preferences, and particular circumstances should be taken into account. This mutualistic approach to clinical management is referred to as Shared Decision-Making. Shared Decision-Making (SDM) is a joint process of choice selection between providers and patients in clinical scenarios where multiple reasonable management options exist. To improve syncope emergency care, the researchers can leverage recent advances in risk stratification to engage patients in SDM and deliver superior, patient-centered care. This study will provide the groundwork for a larger, randomized controlled trial evaluating the effects of the decision aid for management of low-risk syncope.
Different approaches to cardio-neuroablation (CNA) to treat neurally mediated syncope, sinus node dysfunction, and functional atrioventricular block have been published. Investigators have developed a more limited and specific approach of CNA, called cardio-neuromodulation (CardNM). This treatment is based on a tailored vagolysis of the sinoatrial node through partial ablation of the anterior right ganglionated plexus (ARGP); it is also based on an innovative anatomic strategy. The feasibility of CardNM has already been tested in our center in a limited first study in humans (CardNMH1), with a favorable outcome for the patients involved. The results of CardNMH1 have been submitted for publication. The purpose of this second study of CardNM in humans (CardNMH2) is to collect more procedural and clinical data in well-defined patient groups.
The purpose of this research is to test the clinical value of a new P-wave sensitive recording vector compared to a standard ECG limb lead II vector from similar easy-to-use long-term cardiac rhythm monitoring patch systems, the Carnation TM Ambulatory Monitoring (CAM) System and the Zio-XT iRhythm. The P-wave is a critical aspect of the electrocardiogram. The purpose of this study is to see if the P-wave centric focus of the CAM system improves arrhythmia diagnosis.
Almost everyone is aware these days is aware about the risk of smoking. Still many people start this habit specially in early life and during college year. We aim to investigate in this study if there is a drive to smoke in people with vasovagal tendency to improve their symptoms, even if not aware of this. Vasovoagal symptoms are common and include dizziness, smoking, sweating, abdominal pain, fatigue and syncope. Some studies have shown correlation between smoking and a positive tilt table test which is indicative of vasovagal tendency. By collecting the information regarding smoking habit and vasovagal symptoms analysis can be done to see if there is correlation between these two factors
