Palpitations in children are common and obtaining symptom-rhythm correlation is diagnostic, but challenging to obtain. The AliveCor KardiaMobile monitor is a smartphone-based single-lead ECG event recorder with limited study in children. We compared using this smartphone recorder to a conventional (Cardiocall) event recorder.
We performed a prospective, randomized study of children presenting to pediatric cardiology for investigation of palpitations who require an event recorder for symptom-rhythm correlation. Patients were randomized to the smartphone or conventional recorder for rhythm documentation for 3 months or 4 weeks, respectively. Diagnostic tracings were defined as one pathologic arrhythmia or three sinus rhythm tracings. We assessed tracing quality, diagnoses obtained, and time to diagnosis between groups. Patients were surveyed to assess perceptions of using the devices.
One hundred participants were enrolled and randomized to 50 in each group. Diagnostic tracings were achieved in 51% versus 44% (p = 0.525) in the smartphone versus conventional group at means of 23.7 (SD 36.4) versus 11.5 (SD 15.2) days, p = 0.181. Participants who used the smartphone monitor were more likely to transmit recordings (70% vs. 49%, p = 0.037) and more often willing to use the device again (87% vs. 42%, p = 0.015), with no differences between groups in finding episodes easy to record (74% vs. 100%, p = 0.15), easy to transmit (70% vs. 46%, p = 0.26), or overall satisfaction (83% vs. 58%, p = 0.13).
Smartphone monitor devices provided similar diagnostic yield to conventional monitors in children. Families who used the smartphone monitor were more willing to use the device again.
儿童心悸很常见，获取症状与心律的相关性对诊断有帮助，但很难做到。AliveCor KardiaMobile监测仪是一款基于智能手机的单导联心电图事件记录仪，在儿童中的研究有限。我们将这款智能手机记录仪与传统（Cardiocall）事件记录仪进行了比较。
我们对因心悸到儿科心脏病科就诊、需要事件记录仪来确定症状与心律相关性的儿童进行了一项前瞻性随机研究。患者被随机分为使用智能手机记录仪或传统记录仪记录心律，分别记录3个月或4周。诊断性心电图记录被定义为一次病理性心律失常或三次窦性心律记录。我们评估了记录质量、获得的诊断结果以及两组之间的诊断时间。对患者进行调查以评估他们对使用这些设备的看法。
共招募了100名参与者并随机分为两组，每组50人。智能手机组和传统组的诊断性心电图记录比例分别为51%和44%（p = 0.5），平均诊断时间分别为23.7天（标准差36.4）和11.5天（标准差15.2），p = 0.181。使用智能手机监测仪的参与者更有可能传输记录（70%对49%，p = 0.037），并且更愿意再次使用该设备（87%对%42，p = 0.015），两组在记录发作是否容易（74%对100%，p = 0.15）、传输是否容易（70%对46%，p = 0.26）或总体满意度（83%对58%，p = 0.13）方面没有差异。
智能手机监测设备在儿童中的诊断率与传统监测设备相似。使用智能手机监测仪的家庭更愿意再次使用该设备。
