肥厚型心肌病具有复杂的病因,通常可随着疾病的进展引起急性心肌梗死、恶性心律失常及猝死等其他疾病与症状,导致病情进一步的加重,其中以恶性心律失常最为常见[1]。因此,对肥厚型心肌病引起恶性心律失常的情况给予早期判断并采取积极有效的方法进行治疗至关重要。QTcd、QTd作为能够反映出心室负极的离散度指标,用于判断心肌电活动稳定状况具有一定的价值[2]。现我院对肥厚型心肌病患者QTcd、QTd与恶性心律失常
Hypertrophic cardiomyopathy has a complex etiology and often causes other diseases and symptoms such as acute myocardial infarction, malignant arrhythmia and sudden death as the disease progresses, resulting in further aggravating conditions, of which malignant arrhythmias are the most common [1]. Therefore, it is important to give early judgment and take a proactive and effective approach to the management of hypertrophic cardiomyopathy-induced malignant arrhythmias. QTcd, QTd as a ventricular can reflect the degree of dispersion of indicators of the negative, used to determine the stability of cardiac electrical activity has a certain value [2]. Now our hospital on patients with hypertrophic cardiomyopathy QTcd, QTd and malignant arrhythmia
