Response to Letter Regarding Article, "Stress-Induced Cardiomyopathy Presenting as Shock"

First of all, we would like to appreaciate your deep interest in our case report. Fortunately, we have a previous electrocardiogram (ECG) of the patient before the symptom onset (Fig. 1). And we did check the serial ECGs during the admission. At initial admission, there were no prominent ST and voltage changes in precordial leads (Fig. 2). Follow-up ECG taken after 3 hours from the first ECG showed slight ST elevations of precordial leads (Fig. 3). The ECG findings seem to be consistent with low QRS voltage criteria of Takotsubo syndrome of the previous report. During hospital days 2 (Fig. 4) and 3 (Fig. 5), serial ECGs showed progressive worsening of previous low QRS voltages in all leads. On the 14th day of admission, QRS voltages in precordial limb leads became bigger with pISSN 1975-4612 / eISSN 2005-9655 Copyright © 2016 Korean Society of Echocardiography www.kse-jcu.org
