Surveillance of arrhythmia in post-myocardial infarction patients using wearable ECG patch devices: a prospective cohort study
ABSTRACT
Background:
Acute myocardial infarction may be associated with new-onset arrhythmias. Myocardial infarction patients may manifest with serious arrhythmias such as ventricular tachyarrhythmias or atrial fibrillation. Frequent, prolonged electrocardiogram (ECG) monitoring can prevent devastating outcomes by these arrhythmias.
Objective:
We investigated the incidence of arrhythmias in post-myocardial infarction patients using a patch-type device: ATP-C120.
Methods:
This study is a non-randomized, single-center, prospective cohort study. We evaluated 71 patients with post-myocardial infarction who had been admitted to our hospital. The ATP-C120 device was attached for 11 days and analyzed by two cardiologists for new-onset arrhythmic events.
Results:
One participant was concordantly diagnosed with atrial fibrillation. Atrial premature beats occurred in 91.5% and 84.5% of participants, and ventricular premature beats occurred in 53.5% and 62.0%, respectively. Interestingly, 56.3% of the patients showed less than 2 minutes of sustained paroxysmal atrial tachycardia. Among participants with atrial tachycardia, the use of beta blockers was significantly lower (70.0% vs. 90.3%, p=0.037). However, different dosages of beta blockers did not show significant differences.
Conclusions:
Wearable patch ECG monitoring devices are easy to apply and can correlate symptoms and ECG rhythm disturbances among post-myocardial infarction patients. Further study is necessary regarding clinical implications and appropriate therapies for arrhythmias detected early, post-myocardial infarction, to prevent adverse outcomes.
