Research ArticleOpen accessPhrase in the titlePerinatal Cardiovascular Evaluation in Dorper Sheep Echocardiographic Description and Behavior of the Heart Rate Variability on the FieldAmanda Sarita Cruz Aleixo, Mayra de Castro Ferreira Lima, Ana Luísa Holanda de Albuquerque et al.The heart is innervated by the autonomic nervous system, with a predominance of sympathetic and parasympathetic activity associated, respectively, with increases and decreases in the heart rate, as illustrated by the Heart Rate Variability (HRV). Pregnancy induces significant changes in the maternal cardiovascular and hemodynamic systems. This study aimed at evaluating changes in the clinical and echocardiographic parameters of pregnant … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 4 · 3 Nov 2021 · 6,518 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleShort-Term Effects of Aroma Therapeutic Herbal Steam on Heart Rate Variability and StressPeerada Damapong, Pongmada DamapongThis experimental research aims to examine the short-term effects of aroma therapeutic herbal steam on heart rate variability and stress. In this experimental study, the participants were 60 diabetic patients with stress who had rated their stress in the Suang-prung Stress Test-20 at the level of 3 or higher. They were divided into the treatment group (n = 30) and … …American Journal of Applied Sciences, Vol. 15, Issue 7 · 4 Sep 2018 · 8,671 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleVelocity of Heart Rate Recovery in Post-Exercise Under Different Protocols of Active RecoveryMaria Angela Magalhaes De Queiroz Carreira, Felipe Montes Pena, Mauricio B.F. Rachid et al.Abnormalities in the modulation of parasympathetic activity have been identified as a possible pathophysiological link with the association between decreases in heart rate recovery after exercise test. Hypothesis: To investigate if the application of different protocols of active recovery promotes difference in reducing Heart Rate (HR) in Post-Exercise (PE). This was a prospective, randomized trial of patients undergoing Exercise Testing … …Current Research in Medicine, Vol. 4, Issue 2 · 12 Nov 2013 · 7,004 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleHeart Rate Variability Analysis in Different Age and Pathological ConditionsM.E.S. Chelladurai, N. KumaravelProblem statement: Heart Rate Variability (HRV) has been used as a measure of mortality primarily with patients who had undergone cardiac surgery. The analysis of Heart Rate Variability (HRV) demands specific capabilities which are not provided either by parametric or nonparametric conventional estimation methods. The Empirical Mode Decomposition (EMD) adaptively estimates the Intrinsic Mode Functions (IMFs) of nonlinear nonstationary signals. … …Journal of Computer Science, Vol. 7, Issue 10 · 4 Aug 2011 · 6,818 accessesView PDFCite

To determine the cardiovascular effect of AP, we tested the pharmacological responses of aqueous and methanolic extracts of AP on blood pressure (BP) and Heart Rate (HR) of normotensive and ephedrine induced hypertensive rats using a tail-cuff computerized … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 7,654 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIoT-Based Technology Solution for Monitoring Small Breed Cardiac Dogs with Heart DiseaseJeremias Evangelista, Carlos Izarra, José Luis Castillo-Sequera, Lenis WongCaring for geriatric small-breed dogs with heart disease from home is a challenge due to the lack of technological tools available in the market, specifically in South America. This lack limits the quality of life of these canine companions and hinders early detection of cardiac problems. Heart disease is common in geriatric dogs of small and medium breeds and the … …Journal of Computer Science, Vol. 20, Issue 10 · 22 Jul 2024 · 5,465 accessesView PDFCite
