Differences in Negative T Waves Between Takotsubo Cardiomyopathy and Reperfused Anterior Acute Myocardial Infarction

Differences in Negative T Waves Between Acute Pulmonary Embolism and Acute Coronary Syndrome

“…7, 8 The mechanisms responsible for the different distributions of Neg T and peak Neg T in APE and ACS are uncertain, but may involve differences in underlying electrophysiologic conditions between these 2 diseases. In ACS, the ischemia-related artery and its perfusion territory can be predicted on the basis of the distribution of Neg T. 7,8,14, 20 In patients with ACS caused by LAD disease, Neg T was distributed primarily around lead aVL in limb leads and leads V2-4 in precordial leads, facing the lateral region and the anterior region of the left ventricle, respectively. Peak Neg T was also mainly found in leads V3-4.…”

Epidemiology and Clinical Profile of Takotsubo Cardiomyopathy

“…This ECG pattern is similar to that in reperfusion-treated acute MI with minimal biomarker release, considered a manifestation of electrophysiologic stunning. 46 It has been suggested that the prolonged QT interval may predispose TTC patients to torsade de pointes ventricular tachycardia (Figure 3). 47 …”

Acute myocardial infarction caused by left anterior descending artery occlusion presenting as inferior ST elevation and anterior ST depression

“…Inferior ST-segment elevation during anterior wall acute myocardial infarction (AMI) due to LAD coronary artery occlusion is uncommon [3,4]. Usually, 2 conditions are thought to be necessary for these findings: relatively small mass of ischemic anterior wall myocardium, resulting in a weaker anterior injury current and less reciprocal inferior ST-segment depression, and a concomitant inferior wall transmural ischemia that further shifts the inferior ST segments upward.…”
