An unusual precipitant of tako-tsubo cardiomyopathy.
A 76-year-old woman presents with acute pulmonary oedema and cardiogenic shock 10h after elective electrical cardioversion for atrial fibrillation. Her echocardiogram shows new wall motion abnormalities with akinesis of the apical and mid segments of the left ventricle and her resting ECG contains deep T wave inversion and QTc prolongation. Angiography reveals non-occlusive coronary artery disease. The echocardiogram on day 6 shows resolution of left ventricular wall motion abnormalities and a return to normal systolic function. The diagnosis of tako-tsubo cardiomyopathy was made. This is the first report of this condition precipitated by electrical cardioversion.
