The actual pathophysiology behind this unusual phenomenon remains unclear, but it has been hypothesized that a sudden catecholamine surge is the cause. Angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs) may … Clipboard, Search History, and several other advanced features are temporarily unavailable. Alas, we are told that cath showed clean coronary arteries, with a picture consistent with Takotsubo Cardiomyopathy. Clinical correlates and prognostic significance of electrocardiographic abnormalities in apical ballooning syndrome (Takotsubo/stress-induced cardiomyopathy). Her arteries were found to be clear, and Takotsubo cardiomyopathy was diagnosed. 2019. The “good news” is that these patients generally have a favorable longterm prognosis — often with full recovery over ensuing weeks (, Accessory pathway conduction illustration, Atrial fibrillation with a rapid ventricular response, Atrioventricular nodal reentrant tachycardia, M.I. Takotsubo cardiomyopathy (TC) is a unique transient nonischemic cardiomyopathy that mimics acute myocardial infarction (MI). ST segments have an abnormally flat shape in Leads aVL, II, III, aVF, V5 and V6. Takotsubo cardiomyopathy is a self-limiting disease typically resulting in normalization of the ECG and of left ventricular systolic function within 1–2 weeks. In my experience — the ECG picture often, the distribution for that of a typical STEMI … — but not uncommonly, cath will be needed to make the diagnosis. Introduction:  |  I agree that this is an atypical ECG pattern for the diagnosis. Eight of 11 patients were found to have ST elevation, of which two patients had ST depression in reciprocal leads. Electrocardiographic findings of takotsubo cardiomyopathy as compared with those of anterior acute myocardial infarction. Electrocardiogram mimics of acute ST-segment elevation myocardial infarction: insights from cardiac magnetic resonance imaging in patients with tako-tsubo (stress) cardiomyopathy. This ECG is taken from an elderly woman with chest pressure radiating to left shoulder for 30 minutes. Santoro F, Brunetti ND, Tarantino N, Romero J, Guastafierro F, Ferraretti A, Di Martino LFM, Ieva R, Pellegrino PL, Di Biase M, Di Biase L. Clin Cardiol. That would have been my guess for the “culprit artery” in this case. Our thanks to Lew Steinberg and Palm Beach Gardens Fire Rescue for donating this interesting ECG. Interesting case from an elder woman with chest pressure! 2017 Nov;40(11):1116-1122. doi: 10.1002/clc.22798. These same drugs can actually worsen hypotension if the basal segments of the myocardium are so hypercontractile that they actually cause dynamic left ventricular outflow tract obstruction similar to that seen in hypertrophic obstructive cardiomyopathy (HOCM). Pathological Q waves were found in five patients, of which two patients had transient Q waves, suggesting less myocardial damage. Treatment is therefore supportive and aims at minimizing complications. 2019 Sep;17(3):123-128. doi: 10.1007/s12574-019-00424-1. eCollection 2019 Apr. J Electrocardiol. In my experience — the ECG picture often “does not fit” the distribution for that of a typical STEMI … — but not uncommonly, cath will be needed to make the diagnosis. Signs and symptoms of Takotsubo cardiomyopathy are similar to acute myocardial infarction. While recognizing that Tako-Tsubo can present with various ECG findings, the present ECG looks rather atypical to me in comparison to "classical " appearance of Tako-Tsubo syndrome: though neither absolutely definitive nor diagnostic, I would have expcted more prolonged QTc and especially ST elevation in inferior leads (in accordance with the peculiar myocardial involvement. I had one patient who had a recurrent episode, but in most cases it occurred only once per patient. I will try to find out more. Methods: Echocardiography is the best means to diagnosis the severe left ventricular systolic dysfunction and wall motion pattern present in a stress-induced cardiomyopathy. The great news is that, universally, the left ventricular function returns to normal relatively quickly, from 1 to 4 weeks. J Electrocardiol. The ECG abnormalities described may be important clues for the clinician to suspect diagnosis of TC in the right clinical setting. She was admitted to the hospital and sent to the cath lab. NIH Interestingly, a similar acute left ventricular dysfunction pattern can occur with cocaine intoxication. Introduction: Takotsubo cardiomyopathy (TC) is a unique transient nonischemic cardiomyopathy that mimics acute myocardial infarction (MI). J Community Hosp Intern Med Perspect. She also complained of nausea with vomiting. 2009 May;157(5):933-8. doi: 10.1016/j.ahj.2008.12.023. Dynamic changes of QTc interval and prognostic significance in takotsubo (stress) cardiomyopathy. Her family offered a history of  unspecified cardiac disease, hypertension, hypercholesterolemia, and dementia. Spectrum and significance of electrocardiographic patterns, troponin levels, and thrombolysis in myocardial infarction frame count in patients with stress (tako-tsubo) cardiomyopathy and comparison to those in patients with ST-elevation anterior wall myocardial infarction. Here is a clip from an echocardiogram of a patient with a stress-induced cardiomyopathy: Here is left ventricular angiography (LV gram) from a patient with a stress-induced cardiomyopathy: The ECG pattern during a Takotsubo cardiomyopathy episode can vary from normal to ST depression, ST elevation or even a left bundle branch block. Anyway, as we all know the diagnosis should be confirmed on echo or ventriculography (apical balooning) or at worst by observing improvement of EF over time. 2008 Jun 15;101(12):1723-8. doi: 10.1016/j.amjcard.2008.02.062.
