Filter by:In this randomized controlled trial, amount of sedation exposure and patient satisfaction is evaluated in patients undergoing catheter ablation for rhythm disorders via an audiovisual distraction. Patients are randomized into intervention group (adiovisual distraction) or controll (no intervention).
During Laparoscopic cholecystectomy, carbon dioxide (CO2) pneumoperitoneal laparoscopic surgery, CO2-pneumoperitoneum activates the sympathoadrenomedullary system to increase the release of catecholamines such as epinephrine (E) norepinephrine (NE) and dopamine (DA). During stress, E and NE are secreted by the adrenal medulla into blood circulation to promote glycogenolysis to increase blood glucose, speed up lipolysis and accelerate heartbeats. Stellate g anglion block (SGB) reters to the blockade of sympathetic nerves including the large area covered by middle cervical, vertebral arterial. stellate ganglions and ther pre- and post- ganglions. SGB affects both peripheral and central nervous systems. In the peripheral system. the sympathetic pre- and post-ganglionic fibers in the innervated areas of stellate ganglion are affected. Therefore, the control of vascular dilatation and constriction, muscular movement, bronchial smooth muscle relaxation and contraction, and pain conduction, by sympathetic nerves is inhibited. In the central nervous system, the hypothalamus is mainly involved in the regulation of systemic autonomic nervous, immune and endocrine systems, and to maintain homeostasis. CO2-pneumoperitoneum causes severe stress-related homeostatic disorders including arrhythmia and blood pressure changes. This study will examine the effects of stellate ganglion block (SGB) on hemodynamics and stress response in patients undergoing CO-pneumoperitoneal surgery.
The aim of our study is to examine the effect of social isolation on physical activity level, health literacy and kinesophobia in heart rhythm disorders.
This study is designed to evaluate the energy requirements of two different Nonvascular ICD (NV-ICD) electrode configurations for achieving successful defibrillation of ventricular arrhythmias.
To determine the associations among biometric data, arrhythmias, subject-reported symptoms and subject wellness.
COVID-19 can cause myocarditis, which can cause myocardial fibrosis. This has been shown to increase mortality and morbidity among athletes. Several efforts have been made to guide sports participation after COVID-19, but not much scientific evidence is present to back-up those guidelines. The current initiative aims gain a heightened insight in this matter.To identify the presence of fibrosis athletes who recovered from COVID-19 will undergo CMR (Cardiac MRI). All athletes will also undergo echocardiography, 5-day Holtermonitoring among others. This will allow to determine whether differences between those with and those without fibrosis are present. If fibrosis is present, athletes will be offered an implantation of a very small monitoring device that will be able to detect arrhythmias with a much higher sensitivity. Also an exercise echocardiography will be performed, to determine the safety of continuation of athletic efforts. Amendment: Recently myocarditis and pericarditis have also been observed after the administration of mRNA-vaccines, specifically after the second dose. The effect of vaccination on exercise capacity is less clear. To investigate this we propose to amend the inclusion criteria for COVIDEX with "athletes undergoing or having undergone COVID vaccination"
Holter monitoring is one of the most widely used diagnostic methods to detect cardiac arrhythmias. Newer Holter monitors may provide some advantages over the more traditional ones. This study will compare the findings of a Holter exam using an innovative 3-lead wireless water resistant device with a conventional device.
Patients scheduled for elective abdominopelvic laparoscopic surgery under general anesthesia were included. Rocuronium was used for the neuromuscular blockade (NMB) and the level of NMB was monitored with train-of-four (TOF) measurements. The participants from whom informed consent had been received were allocated to two groups according to the agent used for reversal of NMB, sugammadex, or neostigmine. The ECG recordings of the subjects were followed with a rhythm Holter device throughout the procedure until the postoperative 12th hour. Additionally, preoperative and immediate postoperative 12-lead ECGs were evaluated for corrected QT calculations and QT dispersion. Proarrhythmogenicity was assessed with QT related measurements. The documented arrhythmic events on the Holter monitoring were designated as clinical end-points.
COLUMBIA CARDS is a pilot study to understand how COVID-19 affects the heart. It is known that COVID-19 can affect the heart in different ways. COLUMBIA CARDS is studying why some COVID-19 survivors develop clinical conditions such as heart inflammation, fluid buildup, blood clots, and other cardiac problems during or after their COVID-19 illness, and why other ones do not. In this study, we will use cardiovascular magnetic resonance (CMR) and transthoracic echocardiography (TTE) to better understand the impact of COVID-19 on the heart.
The aim of this study was to investigate the association between different reperfusion timing and ventricular arrhythmias (VAs) to provide evidence for clinical decision-making for patients with ST-segment elevation myocardial infarction (STEMI). All the participants included in the study were diagnosed with STEMI according to the 4th universal definition of myocardial infarction, with a follow-up of 1, 6, 12 months, respectively. Symptom onset-to-reperfusion timing (SO2RT) and 24h-dynamic electrocardiogram parameters were recorded to compare different SO2RT and VAs during 3 follow-up visits.
