14 Clinical Trials for Various Conditions
Researchers are assessing the ease of use and accuracy of the HeraBEAT™ device, a new device used with a smartphone to monitor fetal heart rate during pregnancy.
The purpose of this research is to compare four different heart rate monitors (Apple Watch Nike III,Fitbit Iconic, Garmin Vivosmart HR, Tom Tom Spark 3) to an Electrocardiograph (ECG) machine to determine the accuracy of the devices. Over the last two decades, there has been a proliferation of commercially available heart rate monitors. Elite athletes often use heart rate measurements to monitor training and fitness levels. In response, fitness companies have offered a variety of heart rate monitors to the general public. Previously, chest strap monitors that measured electrical activity were mainly used to track heart rates. More recently, wrist-worn monitors that use an optical sensor (light) to measure heart rate have gained in popularity. While the accuracy of chest strap monitors has been studied, there is currently no data concerning the accuracy of wrist-worn heart rate monitors. Assessment of the monitors' accuracy is important for subjects who rely upon the heart rate measurements to guide their athletic activity.
The objective of this study is to evaluate the accuracy of four heart rate monitors in cardiac rehabilitation patients during typical, supervised cardiac rehabilitation involving exercise on a treadmill and/or stationary bicycle.
The purpose of the research study "Heart Sounds at Home" is for pregnant SSA or SSA/SSB (Sjögren syndrome B) antibody positive mothers to use a Doppler fetal heart rate monitor to detect abnormal heart rates and rhythms in their babies before they are born.
The researchers are investigating if changing an individual's behaviors may have an impact on outcomes for patients with pulmonary arterial hypertension (PAH). This research will test the efficacy of a home-based exercise program to improve exercise tolerance and physical activity.
This study will be conducted on women in labor. Fetal heart rate monitoring will be conducting using the Novii Fetal ECG/EMG system and comparing it to current standard of care external fetal heart rate and tocometry. These approaches will be compared with the respect to need for additional monitoring, amount of nursing intervention, cost and satisfaction of patients and healthcare providers.
The researchers want to determine if ambient light, plethysmographic , can monitor reliably heart rate, respiration rate and oxygen saturation in infant patients in a hospital setting.
Owlet Baby Care, Inc. has developed a wearable fabric band pregnancy monitor, to be worn around the maternal abdomen incorporating electrocardiogram sensors. The purpose of this proposed test is to collect overnight "at-home" fetal ECG recordings on women during the second half of pregnancy using the pregnancy monitor.
Multi center, randomized controlled study, to determine if a significant decrease in the rate of heart failure re-hospitalizations occurs during a follow-up period when - ReDS guided treatment is used as an adjunct to standard of care.
The aim of this observational comparison study is to compare the HR and respiratory RR of intraoperative surgical patients simultaneously recorded by standard intraoperative monitors and the ATLASense RAPHAEL PolyMonitor. A second aim is to determine the extent of data loss and data gap duration, and validate the PolyMonitor alert system for tachycardia and bradycardia. Additional parameters of non-invasive blood pressure (NIBP) and body temperature will also be compared between the PolyMonitor and standard intraoperative monitors. Finally, this study will provide insight into the logistics of intraoperative use of the PolyMonitor.
The purpose of this study is to see if the Artificial Pancreas (AP) Platform can successfully control blood sugar in people with type 1 diabetes mellitus on insulin pump therapy in a hospital setting. Investigators will also be studying to see if the heart rate informed Control To Range (hrCTR) can improve the performance of the system during and immediately after exercise.
The purpose of this study is to see if the Artificial Pancreas Platform (AP Platform = Cell Phone + Closed Loop Control) can successfully control blood sugar in people with type 1 diabetes mellitus on insulin pump therapy in a hospital setting. Investigators will also be studying to see if information about heart rate can help the AP Platform reduce hypoglycemia related to exercise.
The primary objective of this study is to determine the effectiveness of home digital blood pressure monitoring in aiding providers to maintain blood pressure within a therapeutic range in type B aortic dissection patients upon discharge from the hospital.
The goal of this study is to test the feasibility of guiding as-needed pharmacological rate control of atrial fibrillation (AF) by implantable cardiac monitors and to assess the impact of continuous beta-blocker therapy versus as-needed rate control on the following outcomes: (1) exercise capacity, (2) AF burden, (3) symptomatic heart failure, (4) biomarker assessment of cardiac filling pressures and cardio-metabolic health, and (5) quality of life in patients with atrial fibrillation and stage II or III heart failure with preserved ejection fraction.
