“…In this research, ST abnormalities occurred among nearly 30% of included patients, which was higher than the proportions of patients with other ECG abnormalities. Non-speci c changes in ST-T segment suggested that patients suffered from myocardial ischemia or necrosis [21].…”

Objective This research was conducted to investigate the monitoring values of routine echocardiography (ECG) and two-dimensional speckle tracking imaging (2D-STI) in cardiotoxicity caused by the treatment of breast carcinoma with anthracyclines (ANTH). Methods 100 patients with breast carcinoma were selected and enrolled into normal group (n = 53 cases) and abnormal group (47 cases) according to whether ECG was abnormal. Routine ECG and 2D-STI were employed for the detection, ECG- and 2D-STI-related parameters were compared, receiver operating characteristic (ROC) curves were drawn, and the clinical application values of monitoring methods for two groups were assessed. Results Before chemotherapy, no remarkable statistical difference was detected in routine ECG and 2D-STI parameters between normal and abnormal groups (P > 0.05). After 6 cycles, E/V value of abnormal group was inferior to that of normal group ((0.93 ± 0.16) vs (1.33 ± 0.23). Besides, longitudinal peak strain (SRI) values of rear wall, front spacer, and rear spacer in abnormal group were inferior to those in normal group (P < 0.05). Routine ECG combined with 2D-STI had the best predictive effect followed by 2D-STI and routine ECG. Conclusion To sum up, 2D-STI was a new method for assessing myocardial lesions and possessed significant early clinical monitoring values in cardiotoxicity caused by chemotherapy after the treatment of breast carcinoma with ANTH. It had higher clinical application values than routine ECG.

“…This ECG pattern is associated with an increased risk of ventricular fibrillation, cardiogenic shock, and higher in-hospital mortality rates, especially compared to patients with other types of ST-segment elevation on their ECGs [ 13 ]. It is also associated with hyper-acute STEMI and is considered a sign of impending hemodynamic instability, necessitating rapid and intensive medical intervention for patient survival [ 14 ]. In TCM patients, the emergence of a triangular QRS-ST-T waveform pattern on an ECG is rare (3.2%), but when it occurs, it is linked to more severe physical stress, more severe ventricular dysfunction, higher risk of complications during hospitalization, and worse long-term outcomes in up to 80% of these cases [ 15 , 16 ].…”

Stress-induced cardiomyopathy, commonly known as Takotsubo cardiomyopathy (TCM), is a clinical syndrome characterized by acute and transient ventricular systolic dysfunction that often presents with chest pain and may resemble an acute coronary syndrome. This case report discusses a complex clinical scenario involving an adult female with severe depression who attempted suicide through drug overdose, subsequently developing serotonin syndrome. Her clinical presentation was further complicated by the emergence of a unique lambda-shaped triangular QRS-ST-T waveform fusion ST-elevation electrocardiographic (ECG) pattern closely mimicking an anterolateral occlusive myocardial infarction. The study delves into the clinical implications of this unique ECG pattern in TCM, providing valuable insights into diagnosing and treating such complex cases. This case underscores the importance of recognizing diverse manifestations of TCM and its potential for severe cardiovascular complications.
