Cardiac sarcoidosis diagnosed 7 years after detection of ventricular tachycardia during pharmacologic stress testing

Cardiac sarcoidosis (CS) is a challenging and often elusive diagnosis due to its variable presentation and dynamic nature. Palpitations and arrhythmias are common manifestations of CS, but findings may be subtle or nonspecific. The prevalence of cardiac sarcoidosis is unknown- while it is recognized in only 5% of patients with systemic sarcoidosis, autopsy studies indicate that it is detectable in 20% of cases[1]. Advanced imaging techniques, including cardiac magnetic resonance imaging (cMRI) and positron emission tomography (PET), enhance the diagnosis of cardiac sarcoidosis, but sensitivity may be limited, particularly in cases where the disease is localized or in its early stages.
