Does a wearable electrocardiogram patch device detect new-onset arrhythmias in patients following myocardial infarction?
An 11-day wearable ECG patch monitoring post-myocardial infarction frequently detects subclinical arrhythmias, including paroxysmal atrial tachycardia, which was inversely associated with beta-blocker use.
Wearable patches detect frequent subclinical arrhythmias post-MI; hypothesis-generating for monitoring-guided therapy trials.
BACKGROUND: Acute myocardial infarction may be associated with new-onset arrhythmias. Patients with myocardial infarction may manifest serious arrhythmias such as ventricular tachyarrhythmias or atrial fibrillation. Frequent, prolonged electrocardiogram (ECG) monitoring can prevent devastating outcomes caused by these arrhythmias. OBJECTIVE: We aimed to investigate the incidence of arrhythmias in patients following myocardial infarction using a patch-type device-AT-Patch (ATP-C120; ATsens). METHODS: This study is a nonrandomized, single-center, prospective cohort study. We evaluated 71 patients who had had a myocardial infarction and had been admitted to our hospital. The ATP-C120 device was attached to the patient for 11 days and analyzed by 2 cardiologists for new-onset arrhythmic events. RESULTS: One participant was concordantly diagnosed with atrial fibrillation. The cardiologists diagnosed atrial premature beats in 65 (92%) and 60 (85%) of 71 participants, and ventricular premature beats in 38 (54%) and 44 (62%) participants, respectively. Interestingly, 40 (56%) patients showed less than 2 minutes of sustained paroxysmal atrial tachycardia confirmed by both cardiologists. Among participants with atrial tachycardia, the use of β-blockers was significantly lower compared with patients without tachycardia (70% vs 90%, P=.04). However, different dosages of β-blockers did not make a significant difference. CONCLUSIONS: Wearable ECG monitoring patch devices are easy to apply and can correlate symptoms and ECG rhythm disturbances in patients following myocardial infarction. Further study is necessary regarding clinical implications and appropriate therapies for arrhythmias detected early after myocardial infarction to prevent adverse outcomes.

Kwun et al. (2022) conducted a cohort in Myocardial infarction (n=71). AT-Patch (ATP-C120) wearable ECG device was evaluated on Incidence of new-onset arrhythmic events. Wearable ECG patch monitoring for 11 days in post-MI patients detected atrial premature beats in up to 92%, ventricular premature beats in up to 62%, and paroxysmal atrial tachycardia in 56%.
