Objectives
Narrative objectives1
Low-level tragus stimulation (LLTS) of transcutaneous vagus nerve stimulation (tVNS) is expected to stabilize the sympatho-vagal balance, and is hypothesized to improve left ventricular function and reduce afterload in patients with Takotsubo syndrome. We investigate the acute effects of LLTS compared with sham stimulation.

Interventions/Control_1
In the active LLTS precedent group, a device clip is attached to the left tragus, and stimulation was performed for 1 hour as vagus nerve auricular stimulation. In the Sham stimulation precedent group, a clip was attached to the left earlobe, and stimulation was performed for 1 hour.
Interventions/Control_2
After the Intervention 1, with resting for 1 hour, Sham stimulation is performed in the Active LLTS precedent group, and Active LLTS is performed in the Sham stimulation precedence group, and crossover is performed.
