Filter by:The goal of this observational study is to evaluate the clinical characteristics of patients undergoing permanent cardiac pacing and to compare procedural efficacy and safety of different implantation approaches in the clinical practice of the participating centres. The contribution of non-fluoroscopic anatomical and electrophysiological reconstruction systems to device implantation procedures will also be evaluated. Participants [patients over 18 years old with an indication to receive a definitive pacemaker/intracardiac defibrillator implant] will receive a permanent cardiac pacing implant as requested according to European Society of Cardiology (ESC) guidelines; the investigators will evaluate procedural efficacy and safety of different implantation approaches.
The goal of this clinical trial is to evaluate the incidence of bradycardia during laparoscopic cholecystectomy. The main question[s] it aims to answer are: - Does bradycardia really occurs during pneumoperitoneum/laparoscopic surgery? - If the patient get Glycopyrrolate, Does it really prevent pneumoperitoneum/laparoscopic surgery induced bradycardia?
PROTECT-SYNC study is a multicenter, randomized, controlled trial. A total of 7 medical centers across Republic of Korea will enroll 450 patients during 2 years of enrollment period, and followed for 2 years of follow-up period. The purpose of this study to compare the clinical outcomes of Left Bundle Branch Area Pacing (LBBAP) compared to Right Ventricular Pacing (RVP) in bradyarrhythmia patients who require high burden of ventricular pacing (>40%).
Study of the ventricular activation patterns during left bundle area pacing and compare it with baseline activation during normal sinus rhythm in patients with and without baseline bundle branch conduction disorder.
The clinical study is intended to implement and test the collection and analysis of paired ECG data from the HeartWatch and two comparator devices, an Event Recorder and Holter. The HeartWatch is indicated for extended diagnostic evaluation of patients with transient symptoms of possible cardiac origin such as syncope and palpitations, as well as patients at risk for arrhythmias, but without significant symptoms. While the use of the device itself can be managed by both healthcare professionals and patients, interpretation of the collected data for diagnosis is restricted to healthcare professionals, as the data must be loaded and analyzed separately after recording. Patients indicated for extended ambulatory ECG testing will be approached for participation. Subjects will wear the HeartWatch and an Event Recorder for up to 72 hours or the HeartWatch and Holter monitor for up to 48 hours. Subjects will be asked to document their activities (standing, sitting, walking, exercise, or laying down). Event recorder subjects will collect user-triggered and auto-triggered data, while Holter subjects will record diary information on their activities and any relevant symptoms. Adverse events and user preference for one device versus the other being used in that arm will also be collected from all subjects. Paired ECG data from the HeartWatch and comparator devices is expected to be similar in terms of the events documented and the proportion of data that is clinically interpretable.
Traditional temporary pacing catheter insertion by intracavitary electrocardiogram (IC-ECG) monitoring which only monitoring tip polar, the negative one. The investigators modified the technique by monitoring both negative and positive polar which will be precisely locating catheter tip and indicating the direction of the catheter tip. Extensively used temporary pacing catheter tip has two electrodes which are about 1 cm apart. Distal electrode is negative (-) and active, proximal electrode is positive (+) and indifferent. Investigators use both distal (-) and proximal (+) electrodes which can be attached to any two of the V leads, record as V(-) and V(+). Monitoring positions of the electrodes by V(-) and V(+) could provide more information about the tip position. Comparing the QRS amplitudes between V(-) and V(+), when catheter tip enters right ventricle chamber: the case of V(-) > V(+) infers tip toward apex ventricle wall ; conversely, the case of V(-)<V(+) indicates tip directs to outflow tract. The investigators hypothesis this monitoring will help precisely placement.
The purpose of this registry study is to collect information about routine clinical practices with device implantation to treat bradycardia and cardiac systolic dysfunction (heart rhythm disorders) across global centers of excellence in cardiac pacing. In particular, this study will examine the use of conduction system pacing (CSP) in clinical practice. Information collected in the registry will help researchers better characterize strengths and limitations of current technology and treatments.
The aim of this study is to evaluate mechanical and electrical cardiac dyssynchrony in patients with pacemakers and the right ventricular electrode implanted in His Bundle area.
BACKGROUND AND RATIONALE: There is very limited literature available on the arrhythmia occurrence in the context of an infection by the SARS-CoV2 virus. On the other hand, treatment strategies against the SARS-CoV2 virus may carry a risk of QTc prolongation and pro-arrhythmia/sudden death which may be amplified by concomitant use of other QTc-prolonging drugs and/or ion disbalances. COVIDAR is an international initiative to monitor the occurrence of arrhythmic events in the context of the SARS-CoV2 infection, to identify potential modifiable predisposing factors to reduce their incidence and to inform the best arrhythmia management options in this patient population. MAIN OBJECTIVE: To describe the incidence and type of arrhythmic events in the context of the SARS-CoV2 infection. STUDY DESIGN: patient registry (observational). Patients will not undergo any additional investigations. Only data that is generated during routine clinical care will be collected. STUDY POPULATION: Patients admitted to the hospital highly suspected of or with confirmed COVID-19.
FFR-guided PCI has been performed in National Taiwan University Hospital(NTUH) for many years. Nevertheless, the method of FFR measurement in NTUH is different from that in literature. In this study, the investigator would like to evaluate the effectiveness and safety of NTUH experience in FFR prospectively. First, the investigator will record any intracoronary (IC) injected adenosine-related complications, such as bradyarrhythmia or chest discomfort. Second, the investigator will follow up on the clinical outcome of the participants for 2 years, record if any target lesion failure, target vessel failure, target vessel-related myocardial infarction, and cardiac death. Finally, left ventricular diastolic pressure, serum pro-brain natriuretic peptide (pro-BNP), and high sensitivity C- reactive protein (hsCRP) will be checked and determined their relationships with the maximum dosage of IC adenosine.
