The frequency of the diagnosis of takotsubo cardiomyopathy has increased rapidly over the past few years, possibly due to increasing awareness among cardiologists. At initial presentation the diagnosis remains a challenge because of the close similarity between the presentation of takotsubo cardiomyopathy, and that of ST elevation myocardial infarction (STEMI). Recognition of salient aspects of the medical history at presentation are important in order to organise further appropriate investigations such as echocardiography and left ventriculography at the time of coronary angiogram. Takotsubo cardiomyopathy can be easily missed without ventriculography early after presentation because of the transient nature of left ventricular dysfunction, and in many centres left ventriculogram is not done as standard in the setting of STEMI. The authors advocate left ventriculography in all cases of ST elevation who have unobstructed coronaries. The correct diagnosis of takotsubo cardiomyopathy is very important for future advice and management of the patient. The prognosis of this condition is generally excellent with almost all patients returning to normal within a few weeks. This article examines the takotsubo cardiomyopathy literature and discusses the pathophysiology, clinical features, management, and prognosis of this condition in the context of an illustrated case.

No significant differences were observed between S-ICD eligibility in C-CHD patients and controls. The AV and PV are most suitable in C-CHD patients. No significant impact of postural change was observed for S-ICD eligibility between the two groups. No significant difference was observed in S-ICD eligibility when screening using two or six postures in both groups.

CRT with (atrial transseptal) endocardial LV lead placement is associated with repolarization characteristics that are considered to be less arrhythmogenic than those generated by CS (epicardial) LV lead placement. Further work is needed to determine whether these changes translate to a reduction in proarrhythmia.
