Electrocardiogram series. Shows the electrocardiogram at TTS diagnosis ST segment elevation in anterior and septal walls (V2 and V3), with symmetrical T wave inversion in all anterior segments (DI, aVL, v4 to V6), and prolonged corrected QT interval (more than 500 ms).

Electrocardiograms at TTS diagnosis, at day 2, and day 7 are shown in Figures 1-3, respectively.
Electrocardiogram series. Shows electrocardiogram at day 2 since TTS diagnosis: A slight ST segment elevation (1 mm) in V1 is added compared with previous EKG.

Electrocardiograms at TTS diagnosis, at day 2, and day 7 are shown in Figures 1-3, respectively.
Electrocardiogram series. Shows electrocardiogram at day 7 since TTS diagnosis: A Wellens Pattern (type 1) is now observed in V2 and V3 leads t wave inversions and prolonged QT interval remains.

Electrocardiograms at TTS diagnosis, at day 2, and day 7 are shown in Figures 1-3, respectively.
Global longitudinal strain (Bull's eye plot) at day 0. Akinesia of all middle and apical segments, with circumferential pattern. Global systolic function is severely compromised (GLS -7%).

Global longitudinal strain (GLS) - by speckle tracking technique - was severely reduced (-6.7%), displaying a circumferential pattern in the Bull's eye plot (Figure 4).
Global longitudinal strain (Bull's eye plot) at day 22. There is a remarkable, and practically complete, recovery from the severe initial compromise of the segmentary wall motion abnormalities observed on day 0. Global systolic function is preserved (GLS -21%).

Echocardiographic follow up showed progressive improvement of initial findings, achieving complete recovery at three weeks after diagnosis, with no segmental motion abnormalities, a LVEF of 60%, and a peak GLS of -21% (Figure 5).
