A 5 year old girl presented to the coronavirus assessment centre on a remote Scottish island with symptoms consistent with novel coronavirus 2019 (COVID-19). Her mother was concerned as she had noted the patient to have an irregular pulse. COVID-19 has been shown to cause cardiac arrhythmia and following discussion with tertiary paediatric cardiology services an electrocardiograph (ECG) was recommended. In order to minimise potential spread of coronavirus in the healthcare setting a portable ECG device was immediately delivered to the patient with the ECG tracing being sent electronically to the cardiologist. A formal diagnosis was then communicated to the parents within 2 hours of the initial contact.
