Isolated septal myocardial infarction (MI) is traditionally characterized by the presence of pathological Q waves in leads V and V on the surface electrocardiogram (ECG). The purpose of this study was to determine the relation between this ECG pattern and septal scar on cardiac magnetic resonance (CMR) imaging.
We retrospectively reviewed the medical records of 996 consecutive patients who received both ECG and CMR.
Nineteen patients had a Q wave in leads V and V. Septal scar was present in all 19 patients. Based on CMR imaging criteria, septal scars were ischemic in 8 patients (42%) and non-ischemic in 11 patients (58%).
The results suggest that the presence of a QS pattern in leads V and V on the surface ECG is highly predictive of the presence of a septal myocardial scar, but is not diagnostic for septal MI, even after excluding comorbidities known to produce a pseudo-septal MI pattern.
孤立性间隔心肌梗死(MI)传统上的特征是体表心电图(ECG)上V导联和V导联出现病理性Q波。本研究的目的是确定这种心电图模式与心脏磁共振(CMR)成像上的间隔瘢痕之间的关系。
我们回顾性分析了996例连续接受心电图和CMR检查的患者的病历。
19例患者V导联和V导联出现Q波。所有19例患者均存在间隔瘢痕。根据CMR成像标准,8例患者(42%)的间隔瘢痕为缺血性,11例患者(58%)为非缺血性。
结果表明,体表心电图V导联和V导联出现QS模式高度预示着间隔心肌瘢痕的存在,但即使排除已知会产生假性间隔MI模式的合并症后,也不能诊断为间隔MI。
