Ventricular arrhythmias in heart failure: to treat or not to treat?

abstract：:Despite the decline in rheumatic heart disease worldwide and the use of antibiotic prophylaxis, there is no evidence that the incidence of infective endocarditis is decreasing. In fact, some data suggest it may be increasing. The classical fever of unknown origin presentation represents a minority of infective endocar...
