It presents with a variety of clinical symptoms, making diagnosis difficult for physicians. Myocardial involvement in sarcoidosis is rare, but it worsens prognosis and can lead to mortality. Physicians face challenges in diagnosing cardiac sarcoidosis due to its wide range of symptoms. Cardiac sarcoidosis that affects only the heart without involvement of other organs is extremely uncommon.<br />In this case, we examine the scenario of a middle-aged man who experienced palpitations and was diagnosed with ventricular tachycardia. He remained in stable condition without any other clinical signs suggestive of sarcoidosis. This case highlights the importance of considering sarcoidosis as a potential diagnosis in patients presenting with palpitations and ventricular tachycardia on electrocardiogram, particularly when these symptoms are accompanied by sudden new-onset systolic dysfunction despite normal coronary arteries.
