Cardiac stress test: can assess functional impairment due to coronary heart disease Exercise ECG testing: most often with treadmill exercise Radionuclide myocardial perfusion imaging (rMPI): performed with either exercise or pharmacologic stress Stress echocardiography : also performed with either exercise ...
The invention provides a sensor for measuring both impedance and ECG waveforms that is configured to be worn around a patient's neck. The sensor features 1) an ECG system that inclu
Friedreich’s Ataxia, caused by frataxin gene alteration, results in central sensory pathway dysfunction, leading to progressive gait and limb ataxia, dysarthria, areflexia, decreased vibration sense, and muscle weakness [57]. Cardiac involvement includes LVH progression to systolic dysfunction and arrhy...
To better define the problem the threshold test was combined with the surface ECG recording: threshold tests in VVI and AAI showed respectively atrial and ventricular capture on the surface ECG (Fig.3a,3b), which confirmed the inversion of atrial and ventricular pace/sense connections. Subsequent ...
Voice-over systems and ECG monitoring had neutral results. Lack of direct comparison between different modalities makes it impossible to determine the most effective method. Dutch studies showed predominantly non-significant results, mainly due to underpowered studies or because of a high standard of ...
(ECG),computed tomography(CT) and magnetic resonance imaging (MRI) are gradually becoming more popular. Among these, MRI and echocardiography are the most commonly used diagnostic tools that are used to assess cardiac function through geometric and flow measurements, such as left ventricle (LV) ...
The concept of backward failure was first proposed by James Hope in 1832, who suggested that congestion in HF was attributable to backward pressure in the venous and capillary system as a result of the failing heart's inability to pump forward [35]. This notion is supported by the fact that...
VitalPatch (Vital Connect) is a wearable sensor placed on the chest using an adhesive that collects continuous ECG waveform, 3-axis accelerometry, skin impedance, skin temperature, and information on activity and posture and pairs via Bluetooth to a smartphone which ultimately transmits to a cloud...

Heart failure is a chronic disease, the symptoms of which occur due to a lack of cardiac output. It can be better managed with continuous and real time monitoring. Some efforts have been made in the past for the management of heart failure. Most of these
