Filter by:Sepsis, a life-threatening syndrome, is often accompanied by tachycardia in spite of adequate volume resuscitation to correct hypovolemia and vasopressor medication to correct hypotension. Recently, relevant studies have shown that sustained tachycardia in sepsis was also related to high mortality, and appropriate control of heart rate could improve prognosis. Ivabradine reduces heart rate directly without a negative inotropic effect through inhibition of the If ionic current，which is absent from the traditional rate control drug (beta-blockers). This is a prospective, multicenter, randomized, open label study designed to compare ivabradine with placebo on the difference of heart rate and haemodynamics in patients with sepsis.
The idea that music has an effect on heart rate and blood pressure has existed for some time. In 1918, Hyde and Scalapino [1] reported that minor tones increased pulse rate and lowered blood pressure, whereas "stirring" music increased both blood pressure and heart rate. In the management of many cardiovascular disorders heart rate control is paramount. Furthermore, many cardiovascular investigations (e.g. Cardiac CT) require adequate heart rate control in order to achieve diagnostic images and therefore results. Whilst pharmacologic therapy is available and remains the main strategy for heart rate control, this is not always without consequences. Side effect profiles, patient intolerance and also variable efficacy are limiting factors for pharmacological therapy. Alternative strategies to achieve adequate heart rate control are therefore needed. The aim of this study is to explore the potential use of music to control heart rates and other physiological parameters such as respiratory rate and blood pressure. The central study team hypothesize that by changing the tempo of the music they will be able to influence the natural variations in heart rate. 1. Hyde IM, Scalapino W.

Monitoring individual responses to training is an important key factor to prescribe to most effective training programs. Heart-rate variability (HRV) could be used for monitoring the training status of endurance athletes in order to detect the fatigue status and to assess the adaptation to training. This direct fatigue measuring method has been little used to prescribe or regulate exercise prescription. Moreover, it allows new possibilities for the training load prescription according to an athlete's status, the response to the training load, and the adaptation to training. Regardless HRV-guided training, the athlete performance could also be influenced by precompetitive mood and anxiety, which can also be reflected in the precompetitive HRV scores and the subjective effort perception.
The purpose of this study is to assess the effects of Dexmedetomidine (DEX), on heart rate control in patients with rapid atrial fibrillation (AF) through a pragmatic, randomized, double blinded study comparing the addition of Dex or placebo to standard of care (SOC) treatment.
