Acute atrial fibrillation during dengue hemorrhagic fever

Abstract

Dengue fever is a viral infection transmitted by the mosquito, Aedes aegypti. Cardiac rhythm disorders, such as atrioventricular blocks and ventricular ectopic beats, appear during infection and are attributed to viral myocarditis. However, supraventricular arrhythmias have not been reported. We present a case of acute atrial fibrillation, with a rapid ventricular rate, successfully treated with intravenous amiodarone, in a 62-year-old man with dengue hemorrhagic fever, who had no structural heart disease.

Cardiac Manifestation involvement in Dengue Infection

“…The most common age group affected in our study was 20-39 years (53%). [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39] This is comparable to the study done by Neeraja et al in 2004, in Hyderabad. [18] The mean age in the present study is 30.45 years.…”

“…[21] A diverse range of ECG abnormalities have been reported with dengue, including rate and rhythm abnormalities, heart block, wave form abnormalities, and voltage abnormalities. [22][23][24][25][26][27][28][29][30][31][32][33] Reported rhythm abnormalities include relative bradycardia, [23] sinoatrial block, [24] disorders of atrioventricular conduction (Junctional rhythm), [24,25] second-degree [26] and complete heart block, [22,27] and monomorphic premature ventricular contractions on a background of heart block, [26] atrial flutter, [28] transient [22,29] and persistent [30] atrial fibrillation, self-limiting tachy-brady arrhythmia, [34] sinoatrial block, and uniform ventricular ectopics progressing to ventricular bigeminy. [31] Electrocardiographic features mimicking acute myocardial infarction have also been reported.…”

Fatal Staphylococcal Infection following Classic Dengue Fever

“…18 At first, the patient described in this report did not have any cardiac abnormalities. At the onset of the bacterial sepsis, the patient had only discrete abnormalities in the electrocardiogram, such as sinus tachycardia, despite the anatomopathological diagnosis of bacterial fibrinous pericarditis extending to myocardium.…”

Dengue myocarditis in Singapore: two case reports

“…There have been reports of acute myocarditis, as well as myopericarditis, pericarditis, asymptomatic myocardial dysfunction and cardiac rhythm disturbances, such as atrioventricular blocks, sinus node dysfunction, ventricular ectopic beats, atrial fibrillation, ST-segment and T-wave changes, tachycardia and bradycardia [3,[14][15][16][17][18][19]. Electrocardiogram abnormalities have been reported during the entire course of dengue.…”
