Ventricular tachycardia may represent the first sign of an unknown cardiomyopathy; fewer data are available on the anatomical substrate of the arrhythmia. The aim of the study was to characterize better those patients who usually do not have haemodynamic impairment, but in whom the arrhythmia may be severely invalidating. To that purpose, two recent and sophisticated radiological methods were used, computed tomography (CT) and nuclear magnetic resonance (NMR); both methods allowed a precise characterization of the morphology and function of the right and left ventricle; a tissue analysis was performed that identified regions of lipomatous degeneration both in the right and the left ventricle, particularly with NMR. In conclusion, CT and particularly NMR appear to be able to reveal minimal changes suggestive of a right and/or left cardiomyopathy whose first manifestation is ventricular tachycardias.
室性心动过速可能是未知心肌病的首发症状；关于该心律失常解剖学基础的数据较少。本研究的目的是更好地描述那些通常没有血流动力学损害，但心律失常可能严重致残的患者。为此，使用了两种最新且精密的放射学方法，计算机断层扫描（CT）和核磁共振（NMR）；这两种方法都能精确描述左右心室的形态和功能；进行了组织分析，确定了左右心室脂肪变性区域，尤其是通过核磁共振确定的。总之，CT尤其是NMR似乎能够揭示提示左右心肌病的细微变化，其首发表现为室性心动过速。
