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.
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.
Subjects will be consented to wear the AleriTM sensor prior to, during, and after an Electrophysiology Procedure. During this time, the system will measure the following parameters from subjects: HR, temperature, saline volume/rate, urine production volume, USG, BPO. Data will be retrospectively analyzed to determine if the system effectively operates under these conditions, and can effectively monitor hydration levels of subjects compared to currently available methods.
This is a retrospective, multi center clinical study collecting existing, de-identified subject data from medical records to be analyzed using an independent core laboratory to validate performance of a computational ECG mapping system (vMap™).
This study aimed to analyze the usefulness of telecardiology in the primary health care level using an ECG personal sensor developed in Slovenia.Investigators also wanted to evaluate the satisfaction of patients and their physicians and the cost-effectiveness of this tool.
Researchers are gathering information on the safety and effectiveness of proton radiation therapy in reducing the number of ventricular tachycardia (VT) episodes in subjects who continue to experience VT despite treatment with an implantable cardioverter defibrillator (ICD) and undergoing a previous catheter ablation.
Single-lead electrocardiography (ECG) technologies and photoplethysmography (PPG) deriving smartphone apps are gaining interest in the heart rhythm detection space since these apps have the potential to capture and assess heart rhythms. Proprietary arrhythmia detection algorithms are proven to be reliable and accurate. However, insights into the readability of PPG waveforms by human reviewers remain limited. To the investigators' knowledge, there are no publications available regarding the readability of PPG waveforms by human reviewers. The objective of the study was to assess the readability of PPG and single-lead ECG analysis by medical professionals, with respect to the gold-standard 12-lead ECG diagnosis, and investigate whether additional information positively impacts PPG analysis.
The general objective of the study was to evaluate the impact of two emotional regulation programs, one standardized and face-to-face (MBSR: Mindfulness Based Stress Reduction) and, another, implemented through a mobile phone application (REM_Volver a casa; ERBM_Back home: Emotional Regulation Based on Mindfulness), on the quality of life, the state emotional and psychological and biological variables associated with stress, in a sample of patients with ICD (implantable cardioverter defibrillator). The working hypotheses were that after training in emotional regulation, patients with ICD would have better quality of life, lower symptoms of anxiety, depression and hostility, and lower incidence of ventricular arrhythmias than patients in the control group, as well as that there would be no differences between the two tools used for training.
This study will occur in patients undergoing routine cardiac ablation of his/her arrhythmia with planned use of an irrigated ablation catheter. The main objective of this study is to take intracardiac pressure measurements and pressure waveforms with both a "gold standard" balloon tipped pulmonary artery catheter placed for this study and an irrigated ablation catheter placed as standard of care for the procedure.
