BACKGROUND The clinical spectrum of Brucella infection is quite diverse and characterized by multi-system involvement. Patients present with myocarditis, endocarditis, or pericarditis. Infective endocarditis is the most common cardiovascular complication in patients with brucellosis. Although conduction abnormalities are seen in cases with endocarditis, they are reported very rarely in the sett...

It is difficult for developers, researchers, and consumers to compare results among emerging wearable technology without using a uniform set of standards. This study evaluated the accuracy commercially available heart rate (HR) monitors Consumer Technology Association (CTA) Participants (N = 23) simultaneously wore Polar chest strap (criterion measure), Jabra Elite earbuds, Scosche Rhythm 24 ar...

We present the case of a 59-year-old woman with intense precordial pain 1 h in duration, arterial pressure at 136/84 mm Hg, and cardiac frequency at 72 BPM. The ECG (Figure 1A) showed a preinfarction stage with level 3 ischaemia (pointed T, elevated ST, and disappearance of the S wave) due to occlusion of the right coronary artery (TII>TI) distal to the first right acute marginal one (depressed...

BACKGROUND Little is known of the variations of the heart rate during spontaneous cardioinhibitory neurally-mediated syncope. Their knowledge has both academic and practical implications for the optimization of rate drop response (RDR) pacing mode. METHODS AND RESULTS We describe variations of the rhythm occurring during 48 syncopal episodes documented by implantable loop recorder. The presyn...

INTRODUCTION AND OBJECTIVES The magnitude of the change in heart rate during the first few minutes of the head-up tilt test has been used to predict the test's result. The aim of this study was to investigate whether the heart rate increase during the head-up tilt test potentiated with nitroglycerin is related to the development of syncope. PATIENTS AND METHOD The study included 158 consecuti...

INTRODUCTION AND OBJECTIVES Our aim was to investigate the prognostic value of the resting heart rate (RHR) in a broad unselected population of patients with stable coronary artery disease (sCAD). METHOD Between February 1, 2000 and January 31, 2004, 1264 ambulatory patients with sCAD were recruited into the prospective study. Patients were followed up for major events (i.e. death, acute coro...

Introduction Association of heart rate (HR) with mortality in patients with acute coronary syndrome (ACS) and aged ≥ 80 years are underrepresented in clinical trials. We therefore aimed to investigate the association of HR in atrial fibrillation (AF) versus sinus rhythm (SR) with all-cause mortality in octogenarian patients with ACS. Methods A total of 336 patients with ACS patients and aged ...
