Does dengue affect heart rate?
Does dengue affect heart rate?
Mean heart rates were significantly lower in the dengue group: 87.6 (±12.5) beats/min (dengue) and 104.6 (±14) beats/min (controls) (p<0.0001). Electrocardiographs (ECGs) were available for 10 of the dengue group, and all showed normal sinus rhythm. Three patients with bradycardia had an ECG.
Does dengue cause low blood pressure?
Mild dengue fever causes a high fever and flu-like symptoms. The severe form of dengue fever, also called dengue hemorrhagic fever, can cause serious bleeding, a sudden drop in blood pressure (shock) and death.
Does viral infection cause bradycardia?
Relative bradycardia is defined as lack of physiological increase in heart rate by 10 beats per minute for each degree increase in temperature beyond 38.9 C (102 F). 1 Several Gram-negative intracellular organisms, viral infections, and tick-borne illnesses are associated with relative bradycardia (Table).
Does dengue cause respiratory problems?
Dengue haemorrhagic fever can result in acute respiratory distress syndrome (ARDS) . Dengue virus antigen is found in alveolar lining cells of the lung.

Is there bradycardia in dengue?
The cardiac manifestations in dengue, also an arboviral infection, are invariably benign, transient and self-limited and are attributed to subclinical viral myocarditis, various ECG abnormalities (sinus bradycardia and prolongation of the PR interval) have been demonstrated in 44- 75% of patients with viral …
