Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Syncope commonly is of benign character in children but it can be the first warning sign of a serious condition. Despite considerable testing and expense accurate diagnosis of the underlying cause of syncope is still challenging. The theoretical possibility of an underlying fatal arrhythmia adds remarkable to the mental health challenges of adolescence and the families. Sudden cardiac death (SCD) is a rare but devastating event in children and adolescents.
Syncope and palpitation deserve even higher attention in patients with congenital heart disease (CHD). These patients have an overall higher risk of developing cardiac arrhythmias as consequence of the pre-existing anatomical alterations, as well as the surgical treatment necessary for its correction. In many cases arrhythmia occur earlier in life and sometimes SCD is the first symptom of manifestation.
To study the origin of palpitation and syncope 12 lead electrocardiogram (ECG) and 24-hours Holter monitoring is typically performed. In case of high clinical suspicion, implantable loop-recorder and electrophysiological study can be performed to finally reach a diagnosis. However, it is an invasive test that is thought to be avoided in children if possible and might be poorly tolerated in patients with CHD.
In recent years, technological development has allowed the validation of different tools for detection of arrhythmias by "smart" devices. The "KARDIA" Mobile Cardiac Monitor is a handheld ECG device that enables users to collect and store single-channel ECG recordings using the smart phone, smart watch, or tablet. A recent study has demonstrated the efficacy of this device in the early diagnosis of arrhythmic disorders in adults by performing ECGs twice weekly plus additional ECG if symptomatic. However, its utility for the early detection and diagnosis of arrhythmias in children and patients with a CHD, which have a different normal physiology of the heart rhythm, has not yet been studied.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Mobile ECG Monitoring
Standard care with clinical follow-up plus Mobile ECG Monitoring.
KARDIA Mobile ECG Monitoring (KMCM)
The KMCM will be introduced to the patient of the KMCM arm in the outpatient clinic. The activation and configuration will be done together with the physician in the outpatient clinic (installation of the ECG app, enabling heart rate rhythm notification). Patients are requested to acquired ECGs twice weekly plus additional ECGs if symptomatic. In case of symptoms the patient is asked to generate an ECG and communicate the event timely to the investigator and to the treating physician by sending a report through the ECG app. An e-mail account created for the study will be checked at least once a day. The arrhythmia diagnosis will be performed by the clinician based on the ECG information, independently of the arrhythmia classification automatically performed by the device. In case of stronger symptoms of any kind at any time the patient is asked to request medical help regardless of the KMCM notifications. Change of management will be collected.
24-hour Holter monitoring
Standard care with clinical follow-up plus repeating 24-hours Holter ECG (month 1, 6, 12)
No interventions assigned to this group

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* 24-hours Holter without diagnosis of arrhythmia.
* Having an smart phone, smart watch, or tablet (the patient itself or a family member who lives together with the patient) compatible with KARDIA mobile ECG monitoring.
* Signed informed consent. In cases under the age of \<18 y.o informed consent should be signed by parents or guardians.
Exclusion Criteria
* Being already diagnosed for arrhythmic events.
* Medical, geographical and social factors that make study participation impractical, and inability to give written informed consent.
