COMPLETED
Validation of an iPhone-based Event Recorder for Arrhythmia Detection
Description

In this study, we will evaluate the diagnostic yield of the new AliveCor device versus a 14 day event monitor with the use of both devices simultaneously. We will also examine by means of a questionnaire the compliance, ease of use and patient satisfaction for each device. Hypothesis: 1. The AliveCor monitor will be non-inferior to the 14 day event monitor with respect to diagnosis of the arrhythmia responsible for a patient's symptoms. 2. The AliveCor monitor will have better compliance and acceptability compared to the 14 day event monitor, and thus there will be a greater number of days with recordings from the AliveCor monitor.

Rhythm Express Wearable System vs. Simultaneous Polysomnography for the Diagnosis of Obstructive Sleep Apnea in Adults With Suspected or Observed Atrial Fibrillation
Description

The goal of this observational study is to confirm the accuracy of the sleep algorithm (software) used in the Rhythm Express Wearable System to detect sleep apnea severity. The study involves participants wearing the RX-1 mini cardiac monitor on their chest and a pulse oximeter during a traditional sleep test, known as polysomnography (PSG), conducted in a sleep center. The performance of the device will be evaluated by comparing the results from the Rhythm Express Wearable System with those from the traditional Polysomnography(PSG). Participants will: 1. Complete a Screening Visit to confirm they are eligible to participate in the study. 2. Be trained on the use of the Rhythm Express Wearable System. 3. Wear the RX-1 mini cardiac monitor on their chest for 3-5 days/nights. 4. Wear a pulse oximeter for 2 nights before a scheduled sleep study. 5. Complete a sleep study while wearing the Rhythm Express Wearable System. 6. Complete a telephone follow-up visit 5-10 days after the sleep study.

ACTIVE_NOT_RECRUITING
Detection and Classification of Cardiac Rhythm and Atrial Fibrillation Using a Finger-worn Ring
Description

Everbeat is a finger-worn ring that has a built-in electrocardiogram (ECG). In this study the investigators ensure that the ECG as read by the everbeat correctly classifies heart rhythms and detects atrial fibrillation. Investigators will also correlate the everbeat ECG waveform with a clinical-grade FDA approved electrocardiogram to ensure it may be reliably interpreted by clinicians or other algorithms.

UNKNOWN
Comparison of Continuous Sternal ECG Patch Monitors (Carnation and Zio) Trial
Description

This study is intended to compare the new Carnation patch monitoring system with the Zio patch, which represents the current standard for continuous recording of the ECG over extended periods.

UNKNOWN
Evaluation of a Mobile Cardiac Outpatient Telemetry System Versus Standard Loop Event Monitor
Description

Comparing the arrhythmia diagnostic yield of MCOT as compared to standard loop event monitors in patients presenting with palpitations, syncope or near syncope occurring less frequently than every 24 hours. Patients randomized and are enrolled for 30 days. Prior testing required: 24 hours of non diagnostic monitoring,

ACTIVE_NOT_RECRUITING
Assert-IQ Implantable Cardiac Monitor (ICM) Post Market Study
Description

This is a prospective, non-randomized, multi-center, real-world post-market study to collect and evaluate data regarding the performance of the enhanced atrial fibrillation detection algorithm of the Assert-IQTM Implantable Cardiac Monitor (ICM) device.

COMPLETED
Coffee and Real-time Atrial and Ventricular Ectopy
Description

Atrial fibrillation (AF) and heart failure (HF) are morbid, costly, and incompletely understood diseases that have reached epidemic proportions worldwide. A dose-dependent relationship exists between premature atrial and ventricular contractions (PACs and PVCs) and development of AF and HF, respectively. Identifying and understanding the mechanisms of additional modifiable risk factors for ectopy has the potential to markedly reduce the healthcare burden of these diseases. In considering how to modify the prevalence of these ectopic beats, the investigators believe common exposures in daily life are prime candidates. Current guidelines suggest that caffeine may be an important trigger for frequent ectopy, although large population-based studies have not demonstrated an association between caffeine consumption and development of clinically significant arrhythmias. No study has employed an actual randomization intervention to assess the effects of caffeine on cardiac ectopy. Utilizing the Eureka platform, the investigators plan to utilize the N-of-1 strategy to rigorously investigate the real-time effect of caffeine intake on ectopy.

COMPLETED
Comparison of Continuous Sternal ECG Patch Monitors (Carnation and Zio) Trial
Description

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.

TERMINATED
Ablation of Inappropriate Sinus Tachycardia
Description

Hypothesis- Radiofrequency ablation, targeting the sympathetic input of the sinus node identified by 20Hz stimulation at the junction of the superior vena cava and the right atrium, will effectively reduce sinus rate acutely and will reduce palpitations due to inappropriate sinus tachycardia without the need for pacemaker implantation due to sinus node dysfunction post ablation.

TERMINATED
Efficacy and Safety Study of the Estech COBRA® Surgical System to Treat Patients With a History of Irregular Heart Beats
Description

The purpose of this study is to demonstrate that the Estech COBRA Surgical System is an effective treatment for patients with irregular heart beats who are undergoing heart surgery.
