With the case discussion, we provide a review of various causes of fever that are associated with bradycardia.Differential diagnosis of the underlying causes of bradycardia.Bradycardia (also sinus bradycardia) is a slow resting heart rate, commonly under 60 beats per minute (bpm) as determined by an electrocardiogram.Awareness of this possible clinical finding could help in the early recognition of dengue and potentially reduce complications andThe pathogenesis remains poorly understood with proposed mechanisms including release of inflammatory cytokines, increased vagal tone, direct pathogenic effect on the myocardium, and.
No exact and useful definition exists and the underlying mechanisms are unknown.Despite this, the term is often used in the literature and in clinical practice both as a clinical sign for an individual patient and as a characteristic feature of certain specific diseases.Relative bradycardia is a poorly understood paradoxical phenomenon that refers to a clinical sign whereby the pulse rate is lower than expected for a given body temperature.Relative bradycardia is found in a wide variety of infectious and noninfectious diseases.Physiologically, for each 1 A?f rise in body temperature, there is a commensurate increase in the heart rate of 10 beats/min.
Many infectious and noninfectious causes of relative bradycardia in febrile patients have been described (e.g.Temperature deficit is called relative bradycardia, which is referred to as faget's sign.For every 1 degree of fever the pulse increases by 10 beats/min.The increase in pulse rale is more than 10 beats/minute with per degree (1A?f) rise of temperature.Relative bradycardia is an important diagnostic finding in a variety of infectious diseases.
