ECG characteristics of COVID‐19 patient with arrhythmias: Referral hospitals data from Indonesia

Background Arrhythmia is a significant clinical modifier in COVID‐19 patient outcomes. Currently, data on arrhythmia and ECG characteristics in COVID‐19 from lower middle‐income countries are limited. Methods COVID‐19 was confirmed by polymerase chain reaction testing of a nasopharyngeal sample. All clinical records were systematically evaluated to obtain demographic characteristics and medical comorbidities. The ECG was recorded on admission, in‐hospital, and at discharge. Results Total documented arrhythmia events account for 22% of patients, comprising 6% of new‐onset arrhythmia and 16% of existing arrhythmia. Atrial fibrillation is the most common arrhythmia.
