Intermittent Atrioventricular Block following Fingolimod Initiation

Figure 2

Patient’s heart rate variability analysis of the frequency domain during the 1st day of Fingolimod. Low frequency (line with rhombi) implying cardiac sympathetic tone, high frequency (line with rectangles) implying parasympathetic tone, and the ratio of them (line with triangles) implying ANS abnormality.
