Pulse Wave Analysis to Estimate Cardiac Output
Anesthesiology, 2020 Pulse wave analysis enables cardiac output to be estimated continuously and in real time. Pulse wave analysis methods can be classified into invasive, minimally invasive, and noninvasive and into externally calibrated, internally calibrated, and ...

Low cardiac output syndrome after cardiac surgery: A retrospective analysis
International Journal of Medicine and Medical Research, 2023 Low cardiac output syndrome is a prevalent complication observed after cardiac surgery, related to elevated rates of mortality and morbidity. The study aimed to pinpoint independent risk factors for low cardiac output through the analysis of post-cardiac

Contactless Electrocardiogram Monitoring with Millimeter Wave Radar [PDF]
, 2021 The electrocardiogram (ECG) has always been an important biomedical test to diagnose cardiovascular diseases. Current approaches for ECG monitoring are based on body attached electrodes leading to uncomfortable user experience. Therefore, contactless ECG monitoring has drawn tremendous attention, which however remains unsolved.

The effects of repetitive electric cardiac stimulation in dogs with normal hearts, complete heart block and experimental cardiac arrest [PDF]
, 1955 Direct cardiac stimulation was conducted in the open chest. In normal animals, auricular stimulation at frequencies faster than the spontaneous rate caused little change in vascular pressures or cardiac output.
