A new study conducted by the Stanford School of Medicine indicates that smartwatches may serve as a valuable tool for healthcare professionals in detecting and diagnosing heart irregularities in children. This conclusion has been derived from an analysis of digitized health records of pediatric patients suffering from heart ailments, who are currently under the care of Stanford Medicine Children's Health.

The study has been published in the Communications Medicine journal. Over a period of four years, there were 145 instances where Apple Watch was mentioned in the medical records of patients. Among those patients, there were 41 instances where the smart device was successful in identifying irregular heartbeats, confirmable with conventional diagnostic methods. Of these, 29 received a diagnosis of heart arrhythmia for the very first time.

The frequency with which the standard monitoring methods failed to detect these abnormalities, while the smart device was successful, was surprising, stated Dr. Scott Ceresnak, senior author of the study and professor of pediatrics. Ceresnak, who also happens to be a pediatric cardiologist serving patients at Stanford Medicine, finds it quite impressive how the technology has aided in patient care.

The chief author of the study is Dr. Aydin Zahedivash, a pediatric clinical instructor. Although most arrhythmias detected did not pose a threat to life, patients could experience some troubling symptoms, like rapid heartbeat, fainting, and dizziness, Ceresnak declared.

There are two major complications when it comes to diagnosing heart arrhythmia in children. Firstly, the conventional cardiac diagnostic tools, although they have considerably improved through the years, are still far from being perfect for a child's use. Not too long ago, a child was obliged to wear a Holter monitor for 24 to 48 hours which was about the size of a smartphone, connected with wires to electrodes that were stuck to the child's chest.

Nowadays, the child can wear event monitors, which are essentially a single sticker placed on the chest and can be worn for a few weeks. Notwithstanding the fact that event monitors are more user-friendly and can be worn for a longer period, they occasionally fall off prematurely or cause problems such as skin irritation.

Secondly, even several weeks of unbroken monitoring may not be sufficient to detect the heart's erratic behavior, as the occurrence of arrhythmia in children is quite unpredictable. They might go even months without an episode, making it hard for the doctors to fully understand the situation. In cases like that of Connor Heinz, where he began experiencing an accelerated heart rate at the age of 12, an adhesive monitor was too uncomfortable, and his inconsistent heart rhythms occurred once every few months at most. Knowing that the smartwatch could provide an instant reading the next time Connor's heart rate soared, Ceresnak recommended it to both Connor and his mother, Amy Heinz.
