Introduction Sarcoidosis is a multisystemic, granulomatous disease of unknown aetiology, frequently manifesting as a mild or even asymptomatic pulmonary disease.1 Cardiac sarcoidosis is the second most common cause of death in sarcoidosis patients globally and the first among Japanese sarcoidosis patients.1 The pathology consists of granulomatous inflammation of the pericardium, myocardium and endocardium with patchy, multifocal involvement. Several infectious organisms have been suggested as possible agents in the aetiology of sarcoidosis, although Propionibacterium acnes (P. acnes) is the only microorganism to be isolated from sarcoid lesio

Introduction In ambulatory individuals with high-grade atrioventricular (AV) block, it is well-established that restoration of AV synchrony with dual-chamber pacing confers important physiological benefits over single-chamber pacing, including improvements in exercise capacity, reduction in incident atrial fibrillation (AF), and avoidance of pacemaker (PPM) syndrome.1,2 The impact of dual-chamber pacing on mortality remains disputed and, in older people, it has been proposed that the expected advantages of physiological pacing strategies may be mitigated by the higher prevalence of comorbidities and non-arrhythmic death.1,3 Accordingly, the

Case A 56-year-old man was referred from the emergency department for further evaluation of recurrent dizzy spells. The patient reported that he had intermittent episodes of palpitations associated with pre-syncope, but denied loss of consciousness. Additionally, he was feeling generally unwell and tired.
