**5. Diagnosis**

The diagnosis of this condition in particular starts with a high index of suspicion; other possible causes must not be overlooked, taking into consideration the wide clinical spectrum of this pathology. The treatment of this condition requires a significant medical effort with clinical imaging and, in many cases, histological correlation.

Cardiac compromise due to sarcoidosis should be suspected when the following conditions take place in which the most frequent causes are excluded [15]:


In addition, clinical suspicion should be higher in all patients with antecedents of extracardiac sarcoidosis that occurred with a cardiovascular symptom such as syncope, arrhythmias, or cardiac insufficiency.

Thus, the diagnosis of this pathology starts with clinical suspicion generated after a detailed medical record and an exhaustive physical exam of those conditions that might explain the current clinical picture is ruled out and identification of extracardiac compromise is found to be due to sarcoidosis.

The use of complementary studies should follow a logical sequence that supports or rules out the suspicion generated in the clinic. The following complementary tests must be performed:
