The CardioSTAT is a single-lead ambulatory electrocardiography monitor that has been validated for use in adult patients. Recording is made through 2 electrodes positioned in a lead-I configuration, and the device allows monitoring for 2, 7, or 14 days. We sought to investigate the efficacy of this device in children with paroxysmal palpitations.
In phase I, the quality of tracings from simultaneous CardioSTAT recordings and D1-lead recordings of a standard 12-lead electrocardiography machine in 23 children were compared. Phase II was a prospective observational cohort study comparing arrhythmia detection using the CardioSTAT vs currently used devices (24-hour Holter monitor and the Cardiomemo loop recorder) in 52 children complaining of palpitations.
In Phase I, all but 3 rhythm strips were correctly identified. The pacing spikes on 3 strips were not adequately identified by the observers for the CardioSTAT recording. In Phase II, symptomatic episodes were reported in 42%, 73%, and 100% of subjects during monitoring with the Holter, Cardiomemo, and CardioSTATdevices, respectively. An abnormal rhythm was detected in 13%, 23%, and 35% of subjects by the Holter, Cardiomemo, and CardioSTAT monitors, respectively. The underlying rhythm during symptomatic events was determined in 90% of cases with the CardioSTAT monitor, whereas it was determined in only 19% and 29% of cases using the Holter and Cardiomemo monitors, respectively.
The CardioSTAT monitor provided good-quality tracings and was superior to the 24-hour Holter monitor and the Cardiomemo loop recorder in determining the presence or absence of pathologic arrhythmia in the study cohort.
CardioSTAT是一种单导联动态心电图监测仪，已被证实可用于成年患者。通过以I导联配置放置的2个电极进行记录，该设备可进行2天、7天或14天的监测。我们试图研究该设备在阵发性心悸儿童中的疗效。
在第一阶段，比较了23名儿童同时使用CardioSTAT记录和标准12导联心电图机的D1导联记录的心电图质量。第二阶段是一项前瞻性观察队列研究，比较了52名主诉心悸的儿童使用CardioSTAT与目前使用的设备（24小时动态心电图监测仪和Cardiomemo动态心电图记录仪）检测心律失常的情况。
在第一阶段，除3条节律条外，所有节律条均被正确识别。观察者对CardioSTAT记录的3条节律条上的起搏尖峰识别不充分。在第二阶段，分别使用动态心电图监测仪、Cardiomemo和CardioSTAT设备监测时，有症状发作的受试者比例分别为42%、73%和100%。动态心电图监测仪、Cardiomemo和CardioSTAT监测仪分别在13%、23%和35%的受试者中检测到异常节律。在有症状事件期间，CardioSTAT监测仪在90%的病例中确定了基础节律，而使用动态心电图监测仪和Cardiomemo监测仪分别仅在19%和29%的病例中确定了基础节律。
CardioSTAT监测仪提供了高质量的心电图记录，在确定研究队列中是否存在病理性心律失常方面优于24小时动态心电图监测仪和Cardiomemo动态心电图记录仪。
