电心电图先行性与急剧的解剖进展在角性缩性心肌病:一个案例报告
1Department of Cardiology, Shanxi Cardiovascular Hospital, Taiyuan, China. 1611064724@qq.com.
电心电图中T波逆转 (TWI) 的快速进展可能表明心肌缩性心脏病变 (ApHCM). 这个案例显示TWI升级促使ApHCM诊断,突出显示了当心声图无法确定时需要心脏磁共振 (CMR) 的需要.
科学领域:
- 心脏病学 心脏病学
- 医疗成像医学成像
- 电子生理学 电子生理学
背景情况:
- 在心前线的深度T波逆转 (TWI) 是一个标志着垂直缩性心肌病 (ApHCM) 的标志物.
- 在ApHCM中TWI的时间进展可能是可变的.
- 早期的表型线索可能是微妙的,并错过了标准评估.
研究的目的:
- 报告一个带有显著T波逆转 (TWI) 进展的角性缩性心肌病变 (ApHCM) 病例.
- 强调心磁共振 (CMR) 的诊断实用性,在不断演变的心电图发现的情况下.
- 突出认识到快速TWI变化作为ApHCM的潜在指标的重要性.
主要方法:
- 一个39岁的男性的病例报告,心电图的发现正在演变.
- 胸外回声心电图用于评估心脏结构和功能.
- 心脏磁共振 (CMR) 用于心肌缩的详细解剖评估.
主要成果:
- 该患者在四年内表现出稳定,低幅度的TWI,随后迅速进展到巨大的,不对称的TWI (10毫米).
- 最初的心声回声显示轻微的顶顶壁加厚,后来通过CMR证实为孤立的顶顶缩.
- 他被诊断为心肌缩性心脏病变 (ApHCM),这表明了电解剖转换.
结论:
- 经过一段时间的稳定之后,TWI的快速进展证明了对ApHCM的临床怀疑.
- 声心图可以在早期的ApHCM中产生假阴性结果.
- 密切的患者监测和及时的CMR对于准确的ApHCM诊断至关重要.

Correlation between ECG and Cardiac Cycle
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
