Filter by:The benefits of regular physical activity are well-established. Furthermore, the investigators have previously shown that in a population of patients with implanted pacemakers, those who exercise more than 2 hours daily have improved survival compared with those who exercise less than 2 hours daily. In this study, the aim f the investigators is to determine whether the offering subjects with pacemakers who have low levels of physical activity at baseline counseling to increase physical activity levels is effective as measured by their implanted device as well as by an external pacemaker. The investigators seek to enroll about 30 patients into a 6-month 1:1 randomized interventional trial comparing the levels of physical activity in 2 groups, those who receive physical activity counseling versus usual care. The activity levels will be measured with external pedometers and with accelerometers embedded within the pacemaker device.
The use of vasopressor supplement materials to local anesthetics is commonly used in procedures in various fields of dentistry, ENT (ear, nose, and throat), Plastic Surgery, Hand surgery and gastroenterology. Epinephrine is used to constrict small blood vessels, thus reducing bleeding during a medical procedure, reducing the toxicity by reducing systemic absorption of local anesthetic, and prolonging the duration and intensity of neural blockage created by the local anesthetic. There are descriptions in the literature of cases in which the use of lidocain and adrenaline caused adverse cardiac events such as arrhythmias, edema and increase in blood pressure during ENT and dentistry procedures. As far as we know there has never been a systematic examination of the incidence and severity of arrhythmias during procedures with local anesthesia. The purpose of the study: 1. To examine the prevalence and types of arrhythmias in patients undergoing a medical procedure performed under local anesthesia 2. Examine whether adding adrenaline to the local anesthetics affects the incidence of arrhythmia Determining the prevalence and types of arrhythmia will help determine the need for monitoring and type of monitoring required during procedures under local anesthesia. The patients: 500 patients undergoing surgery or a medical procedure in which a local anesthetic is used at Meir Hospital. Patients with a medical history of known cardiac arrhythmia will not be included. Methods: Patients will undergo the medical procedure prescribed for them, using local anesthesia with or without adrenaline, at the discretion of the surgeon, in accordance with the usual routine being applied nowadays. The amount and type of anesthesia used will be registered. In addition to the routine monitoring that is currently performed (blood pressure cuff and non-invasive blood oxygen saturation) a continuous ECG monitoring device will be connected prior to the beginning of the surgical procedure, until the patient is discharged from the recovery room. The ECG monitoring results will be analyzed to detect arrhythmia. Side effects being reported by patients (palpitations, dizziness, fainting, CPR {cardiopulmonary resuscitation} ) will be recorded. In cases that an arrhythmia is detected, the type of arrhythmia and the presence of clinical symptoms will be investigated.
Valiosa is a national, multicenter and prospective post market study. The objectives of the study are to generate and validate an instrument to evaluate patient and clinician's satisfaction with remote monitoring and to create awareness of the importance of remote monitoring among patients, physicians and decision makers.
The primary requirement of the implantable cardioverter defibrillator (ICD) is to preserve life by terminating life-threatening arrhythmias (VT/VF). The treatment options vary in terms of techniques and medical devices, based on the patient's condition. It is extremely important in the clinical practice to identify which patients' subgroup benefits the most from the ICD therapy, which comorbidity has a major impact on the patients' prognosis, or which pre-intra-post procedural behaviors provoke less complications, and affect the patient's outcome (including prolonged or unwanted hospitalizations).
The objective of this study will be to evaluate the ability of IEGMs (Signal recorded from implanted pacing leads) and pseudo ECGs (derived from various IEGMs) to characterize various electrical conduction patterns. Electroanatomic mapping data and 12 Lead ECG will also be collected to characterize electrical conduction patterns during standard electrophysiology exam.
The aim of this study is to compare the efficacy of group training using a tutorial film and one-to-one face-to-face training in calculating the pulse rate and detecting irregularity in the pulse rhythm in patients with cardiovascular diseases.
Clonidine, an agonist for alfa2 pre-synaptic, has been shown to be an effective adjuvant therapy for acute postoperative pain and has been shown an effect in sedative, intra-ocular and blood pressure and arrhythmias.The objective of this study is evaluating the analgesic effect of clonidine and its repercussion on arterial and intraocular pressure and arrhythmias for cataract surgery.
The ABCD clinical study (ClinicalTrials.gov Identifier NCT00187291) was designed to determine if a T-Wave Alternans (TWA) test is equivalent to an Electrophysiology Study (EPS) in predicting life-threatening heart rhythms in patients with ischemic heart disease, left ventricular dysfunction, and non-sustained tachycardia. The purpose of the ABCD Genetic sub-study is to identify genetic markers that predict TWA status and arrhythmia risk in this same population.
Patients with several heart arrythmia can potentially be cured by catheterablation. For some arrythmias 95% of the patients are cured. Also patients with atrial fibrillation are cured by catherablation even though the effect is not as impressive as for other cardiac arrythmias. About 70% of patients with paroxystic and persistant atrial fibrillation are cured. Most of the remaining obtain a reduction of their symptoms. At conventional ablation of atrial fibrillation the catheters are manually navigated to the ideal anatomic position where to isolate the pulmonary veins from the left atrium. Lately it has been possible to navigate the ablationcatheters using 'remote magnetic navigation' using a magnetic based navigation equipment, Stereotaxis. The Heartcentre of Rigshospitalet had this Stereotaxis equipment installed in the autumn of 2006. We will investigate the utility and safety of using this remote magnetic navigation/Stereotaxis.
Assess whether serum levels of MMP 2 and or MMP 9 correlate with episodes of ventricular tachycardia or fibrillation in patients who have implantable cardioverter defibrillator devices.
