Background Electrocardiogram (ECG) manifestations of takotsubo cardiomyopathy (TC) produce ST-segment elevation or T-wave inversion, mimicking acute coronary syndrome (ACS). We describe the ECG manifestation of TC, including ECG evolution, and its different points from ACS. Methods We studied 37 consecutive patients (age 67 ± 15 years, range 23-89, M:F = 12:25) from March 2004 to November 2012 with a diagnosis of TC who were proven to have apical ballooning on echocardiography or left ventricular angiography and normal coronary artery. We analyzed their standard 12-lead ECGs, including rate, PR interval, QRS duration, corrected QT (QTc) interval, ECG evolutions, and arrhythmia events. Results Two common ECG findings in TC were ST-segment elevation (n = 13, 35%) and T inversion (n = 24, 65%), mostly in the precordial leads. After ST-segment resolution, in a few days (3.5 days), diffuse and often deep T-wave inversion developed. Eight patients (22%) had transient Q-waves lasting a few days in precordial leads. No reciprocal ST-segment depression was noted. T-wave inversion continued for several months. QT prolongation (>440 milliseconds) was observed in 37 patients (97%). There were no significant life-threatening arrhythmias except atrial fibrillation (n = 6, 16%). Conclusion There are distinct differences between the ECGs of TC and ACS. These differences will help to differentiate TC from ACS.

Background: Critical stenosis in the proximal part of the left anterior descending, severe 3 vessel disease and left main stem stenosis have all been recognized as clinical conditions complicated by a high incidence of large infarction, pump failure, arrhythmias and sudden death in patients with acute coronary syndrome (ACS). As many effective treatment modes are available currently, early recognition of those circumstances is crucial for appropriate management.Methods: this observational study was carried out at the Department of Cardiology, National Institute of Cardiovascular Disease (NICVD), Dhaka. Patients (30 patients) with NSTEACS having ST-segment depression with T-wave inversion maximally in leads I,avL,V4-V6 were considered as cases (Group I) and those (30 patients) with ST-segment depression without T-wave inversion in lateral leads were controls (Group II). Coronary angiogram (CAG) was done during in-hospital stay.Results: In present study, it was evident that among group I patients, 43.3% had stenotic lesion in left main artery (LM) and 26.67% in LM equivalent coronary artery (LME CA), whereas had no stenotic lesion in LM and 3.33% had LME CA lesion in group II patients. Low cost, widely available ECG criteria is supposed to be useful predictor of left main or left main equivalent coronary artery obstruction (Sensitivity=95%, Specificity= 76%, Positive predictive value= 70.0% and Negative predictive value= 97.0%) and high ST–segment changes score (>18 mm (100%) &/or ³10mm (80%) was an additive predictor of LM or LMECA lesion.Conclusion: Maximum ST- segment depression with T-wave inversion in the lateral leads I, aVL, V4-V6 on admission ECG can predict the critical LM or LMECA obstruction in patients with NSTEACS. It can help to provide prompt and appropriate management earlier to reduce the mortality & morbidity.Cardiovasc. j. 2017; 9(2): 135-141

Abstract Physicians have encountered cardiotoxicity in different situations. The most known scenario is heart failure after especially anthracycline treatment. In this case, immediately after chemotherapy typical Takotsubo syndrome developed and was diagnosed with normal coronary angiography with apical ballooning movement in ventriculography. Acute cardiotoxicity may depend on different pathogenesis than ordinary toxicity mechanism. Case report A 65 years old female attended emergency department with epigastric pain after chemotherapy. She had vinorelbine and gemcitabine treatment for malignant urotelial renal carcinoma. The patient was consulted with cardiology department, because of progressive high troponin T levels. She had no prior history except urotelial carsinoma for one year and hypertension for seven years. Her prior chemotherapy protocols included carboplatine and docetaxel. She did not describe typical angina pectoris or shortness of breath. Electrocardiography (ECG) at admission had symmetrical T wave inversion on precordial derivations (figure 1). Echocardiography (echo) showed typical apical ballooning of the left ventricle (figure 2 and 3). We do not know the patient’s prior cardiac performance and acute coronary syndrome and Takotsubo syndrome were our preliminary diagnosis. Normal coronary arteries were seen on coronary angiography, ventriculography revealed apical ballooning movement of the left ventricle (Figure 4) and this supported our diagnosis as Takotsubo syndrome. She was already on valsartane 160 mg daily for hypertension and we included metoprolol 50 mg daily and enoxoparine 6000 IU s.c twice a day. For several days deep symmetrical T wave inversion persisted on ECG. After third day her ECG changings resolved (Figure 5) and echo images had recovered. The patient was discharged uneventfully and is followed. Abstract P256 figures
