Antiarrhythmic and proarrhythmic effects of subcutaneous nerve stimulation in ambulatory dogs [PDF]

, 2019
Background High output subcutaneous nerve stimulation (ScNS) remodels the stellate ganglia and suppresses cardiac arrhythmia. Objective To test the hypothesis that long duration low output ScNS causes cardiac nerve sprouting, increases plasma ...

Noninvasive measurement of cardiac performance in recovery from exercise in heart failure patients

Clinics, 2011
OBJECTIVE: To examine the association between cardiac performance during recovery and the severity of heart failure, as determined by clinical and cardiopulmonary exercise test responses. METHODS: As part of a retrospective cohort study, 46 heart failure

A Narrative Review of Cardiac Output Measurement in Cardiac Surgery

Archives of Anesthesia and Critical Care, 2023
Continuous monitoring of the cardiovascular system and control of the changes affecting it is a constant challenge for the surgical team. The need to control the condition of the heart and better understand its condition is raised in the topic of ...

Cardiorenal syndrome type I recovery following heart rate correction: Cardiac output is not only stroke volume

Clinical Case Reports, 2022
Bradyarrhymias can result in low cardiac output state despite having a normal left ventricular ejection fraction and stroke volume. Because cardiac output is defined as the product of heart rate and stroke volume, a low cardiac output state caused by ...

Lower Cardiac Output Relates to Longitudinal Cognitive Decline in Aging Adults

Frontiers in Psychology, 2020
BackgroundSubclinical reductions in cardiac output correspond to lower cerebral blood flow (CBF), placing the brain at risk for functional changes.ObjectivesThis study aims to establish the consequences of reduced cardiac output on longitudinal cognitive

Machine Learning-based Signal Quality Assessment for Cardiac Volume Monitoring in Electrical Impedance Tomography [PDF]

arXiv, 2023
Owing to recent advances in thoracic electrical impedance tomography, a patient's hemodynamic function can be noninvasively and continuously estimated in real-time by surveilling a cardiac volume signal associated with stroke volume and cardiac output. In clinical applications, however, a cardiac volume signal is often of low quality, mainly because of

Metabolically exaggerated cardiac reactions to acute psychological stress: The effects of resting blood pressure status and possible underlying mechanisms [PDF]

, 2010
The study aimed to: confirm that acute stress elicits metabolically exaggerated increases in cardiac activity; test whether individuals with elevated resting blood pressure show more exaggerated cardiac reactions to stress than those who are clearly ...

Effect of a perioperative, cardiac output-guided hemodynamic therapy algorithm on outcomes following major gastrointestinal surgery: a randomized clinical trial and systematic review.

Journal of the American Medical Association (JAMA), 2014
IMPORTANCE Small trials suggest that postoperative outcomes may be improved by the use of cardiac output monitoring to guide administration of intravenous fluid and inotropic drugs as part of a hemodynamic therapy algorithm.

Lactate acidosis and cardiac output during initial therapeutic cooling in asphyxiated newborn infants.

PLoS ONE, 2019
AimWe hypothesized that compromised cardiac output in asphyxiated infants may influence on the rate of disappearance of lactate due to insufficient perfusion.MethodsThe study was a prospective, observational study, where infants with perinatal asphyxia ...

Cardiac Output Monitoring in Preterm Infants

Frontiers in Pediatrics, 2018
Maintaining optimal circulatory status is a key component of preterm neonatal care. Low-cardiac output (CO) in the preterm neonate leads to inadequate perfusion of vital organs and has been linked to a variety of adverse outcomes with heightened acute ...
