Changes in electrocardiogram in patients with cardiac sarcoidosis
Introduction. Abnormalities in the electrocardiogram are more frequent in patients with cardiac sarcoidosis than in those having other diseases. The aim of this study was to determine the types and incidence of abnormalities in the electrocardiogram in patients with cardiac sarcoidosis. Results. The study sample included 30 patients (22 women and 8 men), their mean age being 45 years (23- 64). The clinical diagnosis was confirmed by echocardiography in 25 (83%) and by radionuclide ventriculography technetium-99m in five patients (17%). Abnormal electrocardiograms were found in 28 (93%) patients. The rhythm disturbance was recorded in 21 (69%): arrhythmias in 11 (37%), conduction disturbances in eight (26%), associated in two (6%), changes in the ST-T in 7 (23%). Micro R from V1 to V3 was observed in 15 (50%).patients. The recorded echocardiography granuloma in the septum and occurrence of arrhythmias were highly correlated with electrocardiogram findings ?micro R? V1 to V3 (p <0.007, p <0.02). Conclusion. Unusual, nonspecific changes in the electrocardiogram of patients with cardiac sarcoidosis, such as the finding of reduced tooth R V1-V3, shows a possible affection of the septum and frequent occurrences of dysrhythmias.
