Comparison Study of BNP and Thoracic Impedance Measurements on Arrhythmias

Heart FailureArrhythmias

It is hypothesized that elevated BNP level correlate with an elevated thoracic impedance/fluid index as measured separately by CRT-D devices and external impedance cardiography. Ultimately, it is also hypothesized that both BNP and thoracic impedance/fluid index measurements are predictive of atrial and ventricular arrhythmias.

RECORD-VP: Real-time Evaluation of Cardiac Outpatient Recording Device With VitalPatch RTM

ArrhythmiasCardiac

The primary purpose of this study is to evaluate performance and safety of the VitalConnect Platform when used for mobile cardiac telemetry (MCT) or as an independent diagnostic testing facility (IDTF) system during activities of daily living by subjects 18 years or older who have been recommended MCT by their care provider.

Cloud-Based Mapping for Personalized Ablation

Atrial FibrillationArrhythmias1 more

Atrial fibrillation is a serious public health issue that affects over 5 million Americans in whom it may cause skipped beats, dizziness, stroke and even death. This study seeks to improve our understanding of the causes of atrial fibrillation and to design new and more effective therapy for this heart rhythm disorder.

VitalConnect VitalPatch ECG Interpretation/Arrhythmia Detection

ArrythmiaCardiac

Subjects in this study will wear the VitalPatch with the added ECG Interpretation and arrhythmia detection features which will expedite the identification of patients whose condition may rapidly deteriorate as well as eliminate the majority of non-actionable alarms.

Hypoglycaemia and Cardiac Arrhythmias in Type 2 Diabetes

Diabetes MellitusType 22 more

Twenty-one patients with insulin-treated type 2 diabetes with diabetic complications will be recruited to Part 1 of the study, a three-hour combined hyper- and hypoglycaemic clamp, along with a control group of twenty-one individuals with normal glucose tolerance matched for age, gender, and body mass index. Patients with type 2 diabetes will be scheduled for a three-week run-in period with LR and CGM prior to participation in Part 1. Only patients with a well-functioning loop-recorder and who can comply with CGM will be included. Patients with type 2 diabetes will continue in part 2 of the study, a one year observational study employing CGM and LR and clinical examination after 1, 3, 6, 9, and 12 months and an extended observation period of 2 years employing LR and clinical examination.

Assessment of Ventricular Arrhythmia Risk After CRT-D Replacement for Patients With Primary Prevention...

Cardiac ResynchronizationBiventricular Pacemakers4 more

Cardiac resynchronization therapy (CRT) has been shown to reduce heart failure (HF), hospitalizations and death in patients with left ventricular ejection fraction (LVEF) <35% and wide QRS. CRT provides electromechanical resynchronization and improves LV systolic function. The induced LV reverse remodeling or near normalization in LVEF to ≥45% is associated with a significant reduction in the risk of subsequent life-threatening ventricular tachyarrhythmias (VTA). And at the time of replacement, the need for defibrillator back-up after an event-free first CRT-D service-life for patients with improved LVEF is a controversy question. 80% of Implantable Cardioverter Defibrillator (ICD) patients implanted for primary prevention do not experience VTA during the life-time of their first device. So, regarding patients implanted with a CRT-D for primary prevention at the time of first implantation, the question is will they experience VTA after their device replacement by another CRT-D.
