Filter by:The aim of this study is to evaluate the reliability of smartphone seismocardiographic detection of AF in comparison to the gold standard of continuous telemetry ECG recording.
Feeling of palpitations with no clear arrhythmia is frequently encountered in clinical practice. The majority of these patients have documented sinus rhythm even while having symptoms. Gastrointestinal association with such symptoms was first described by Ludwig von Roemheld (1871-1938).The investigators thought to investigate the effect of proton pump inhibition in patients with feeling of palpitations but no clear cause.

This study evaluates the role of colchicine in the prevention of atrial fibrillation in patients undergoing open heart surgery. Half of participants will receive colchicine and the other half will not
2-3% of emergency department (ED) syncope patients suffer arrhythmia/death within 30 days of disposition (either as an inpatient or at home) and we have recently developed the Canadian Syncope Risk Score (CSRS) to predict these outcomes. Currently, only Holter monitoring is used and is applied a few days later. New and innovative remote (out-of-hospital) external cardiac monitoring technology has made prolonged monitoring possible. The primary objective is to compare diagnostic yield (identification of arrhythmia that requires treatment) for the following two strategies among higher-risk syncope patients discharged home from ED: 15-day external cardiac monitoring (intervention arm) versus 48-hour Holter monitor (control arm) Methods: The study will be a double-blind RCT comparing two different approaches for detecting serious arrhythmias among high-risk ED syncope patients who are discharged home. Cardiophone (live monitor) will be used for the intervention arm and the Mobile Cardiac Telemetry (MCT) device will be used for the control arm and both devices applied prior to ED discharge. For patient safety purposes and to ensure that the patients are similar in both arms, all of the study patients will be monitored for 15 days. MCT will function as a holder for the first 48 hours and this will be used to compare the diagnostic yield in the two study arms. After written informed consent, patients will be randomized 1:1 with allocation concealed by web-based randomization and stratified based on the total CSRS scores. Data collection: patient demographics, medical history, score predictors, device data (failure, false alarms, duration worn), patient symptoms, and comfort. The primary outcome will be the diagnostic yield at 15 days in the two study arms and primary analysis will compare the diagnostic yield by intention to treat principle controlling for the stratification factor. Sample Size: 300 patients per arm (600 total) to detect a 10% difference in diagnostic yield between the arms. Impact: Our study will increase the early identification of patients with serious underlying arrhythmia by combining the CSRS risk tool with innovative remote monitoring technology.
The purpose of this research study is to learn about arrhythmia detection in obstructive sleep apnea (OSA). For several years patients with OSA have an increased likelihood of having irregular heartbeats. This study will determine how often patients with OSA have irregular heartbeats. This study will also define which OSA patients are most likely to have irregular heartbeats. The participant is being asked to be in the study because the participant has been diagnosed with obstructive sleep apnea (OSA).
The aim is to evaluate if internet- delivered CBT, based on behavioral activation and exposure principles, improves wellbeing and QoL in symptomatic AF patients.The study will include 30 patients with symptomatic AF despite optimal medical treatment in accordance with current guidelines.
This is a randomized trial of a best-practice alert delivered via the electronic medical record (Apex) to physicians on the Medicine service at UCSF Medical Center over a six month period. The alert notifies physicians that their order for continuous cardiac monitoring (telemetry) for a given patient has exceeded the duration recommended by national guidelines and offers them the opportunity to discontinue monitoring if they feel it is clinically appropriate. Physicians will be randomized to either receive the BPA or not, with the anticipation that physicians in the intervention arm will discontinue unnecessary telemetry.
Prospective observational multicentric study evaluating the efficacy of considering unipolar signal modification during radio frequency catheter ablation of patients with symptomatic paroxysmal atrial fibrillation in France between November 2013 and January 2015. All procedures were conducted according to the standard clinical care and current guidelines. Pulmonary vein isolation was guided according to force (at least 10 grams) and application vector (perpendicular to the wall) developed until the atrial unipolar electrogram recording became a complete positive signal. Patients were discharged from hospital free of any anti-arrhythmic drugs. Recurrence of arrhythmias at 12 months (primary outcome) was assessed by continuous 48-hour Holter at 1, 3, 6, 9 and 12 months post-catheter ablation.
Sedation for catheter ablation of atrial fibrillation should be performed to achieve analgesia, immobilization, and maintenance of airway. Various anesthetic agents such as propofol, dexmedetomidine, and midazolam were investigated to achieve this goal. However, propofol and midazolam causes respiratory depression and dexmedetomidine occasionally accompanies hypotension or hypertension and bradycardia. Therefore, anesthetic agent that does not induce respiratory depression with stable hemodynamics is needed. Propacetamol (Denogan®, Yungjin, Seoul, Korea) is injectable prodrug of acetaminophen and 1st line drug for fever and pain. In a previous study, paracetamol reduced morphine consumption after surgery. And paracetamol does not cause respiratory depression. Thus, the investigators hypothesized that addition of propacetamol to previously used sedatives midazolam-remifentanil will reduce opioid consumption during the catheter ablation. Therefore, the investigators designed this study to investigate the role of addition of propacetamol to previous used midazolam-remifentanil sedation. This study will compare the opioid consumption and respiratory effect of propacetamol with placebo-control for catheter ablation of atrial fibrillation.
