Electrocardiograms (ECGs) recorded with wearable devices and additional smartphone apps play an increasing role in cardiology.
We present two cases in which it was possible to record an ECG during cardiac-related symptoms using the patients' smartphones. Previous standard resting and 24-hour ECGs had revealed no pathologies. In one case, AV nodal reentry tachycardia was detected and treated accordingly. In the second case, ischemic ECG changes were recorded in a young woman without cardiovascular risk factors during a chest pain episode. Suspecting a coronary vasomotion disorder, an invasive diagnostic procedure was performed. The acetylcholine spasm provocation test revealed coronary microvascular spasm and appropriate therapy was initiated.
Smartphone-based ECG systems which can be used by the patient independently while experiencing cardiac-related symptoms are a modern diagnostic tool. Considering the use of these systems is beneficial for early diagnosis and appropriate treatment for paroxysmal arrhythmias and coronary vasomotion disorders.
可穿戴设备及配套智能手机应用程序记录的心电图在心脏病学中发挥着越来越重要的作用。
我们介绍两例使用患者智能手机在心脏相关症状发作期间记录心电图的病例。之前的标准静息心电图和24小时心电图均未发现病变。其中一例检测到房室结折返性心动过速并进行了相应治疗。在第二例中，一名无心血管危险因素的年轻女性在胸痛发作期间记录到缺血性心电图改变。怀疑冠状动脉血管运动障碍，进行了侵入性诊断程序。乙酰胆碱激发试验显示冠状动脉微血管痉挛，并启动了适当治疗。
患者在出现心脏相关症状时可独立使用的基于智能手机的心电图系统是一种现代诊断工具。考虑到这些系统的使用有利于阵发性心律失常和冠状动脉血管运动障碍的早期诊断和适当治疗。
