Daewoong Pharmaceutical Detects Atrial Tachycardia Early with One-Day Mobicare Wearable

"Importance of Long-Term ECG Screening in Health Checkups"

Recent cases have shown that wearable long-term electrocardiogram (ECG) screening tests can detect arrhythmias that were not identified by conventional 12-lead ECGs, highlighting the growing need to introduce long-duration ECG monitoring at the health checkup stage for early arrhythmia screening.

On March 12, Daewoong Pharmaceutical announced that, during health checkups at the Korea Health Management Association Gyeongnam Branch, a case was identified where the wearable ECG solution 'Mobicare' was used for a one-day arrhythmia screening test, leading to the early detection of atrial tachycardia.

According to the Korea Health Management Association Gyeongnam Branch, a female examinee in her late 60s recently experienced chest pain that felt like tightness every time she walked uphill. As her symptoms persisted, she consulted with a medical professional during her health checkup about the symptoms she had been experiencing. In addition to her pre-scheduled tests, she underwent an ECG, a Mobicare test, and a detailed cardiac examination including a coronary CT scan.

The conventional 12-lead ECG, performed during the checkup, is a short-duration test that concludes within a few minutes. If an arrhythmia does not occur at the time of the test, there is a risk that abnormal findings may be missed. In contrast, Mobicare enables long-term ECG monitoring during daily activities, making it more effective in detecting intermittently occurring arrhythmias.

In this case, the one-day arrhythmia screening test with Mobicare detected signs of atrial tachycardia. Based on the initial opinion of the specialist who reviewed the test, the consulting physician determined that immediate treatment was necessary, recommended a cardiology consultation, and issued a referral letter.

The examinee subsequently received care from the cardiology department at a general hospital in Changwon. A coronary angiography revealed mild stenosis. She is currently managing her condition through medication and ongoing daily care.

Generally, the 12-lead ECG used in health checkups involves attaching 10 electrodes to the chest and limbs to measure the heart's electrical signals from 12 directions, evaluating the heart’s condition over a short period of about 10 seconds. Because the test duration is brief, it is difficult to detect intermittent arrhythmias that do not manifest during the examination.

To observe arrhythmias over a longer period, a 24-hour Holter ECG test is used. However, the Holter test requires expensive equipment and interpretation by an arrhythmia specialist, making it difficult to utilize in checkup centers or primary medical clinics.

In contrast, Mobicare is a wearable ECG solution utilizing two electrodes. The ultra-lightweight device, weighing approximately 19g, can be worn relatively comfortably during daily activities, and it continuously records ECG data for one to nine days, facilitating the effective detection of intermittent arrhythmias. After the test, the device can be returned via courier pickup service, providing convenience for examinees.

Additionally, Mobicare collects ECG data continuously, enabling AI-based analysis and providing a review and interpretation report by an arrhythmia specialist, thus supporting its use even at checkup centers or clinics without an in-house cardiology specialist. This case demonstrates the significance of early detection and rapid referral to specialized medical care for intermittent arrhythmias at the health checkup stage, underscoring the importance of long-term (1-day, 3-day) ECG-based screening.
