SAN DIEGO Research by the Scripps Translational Science Institute (STSI) has found that a small adhesive wireless device worn on the chest for up to two weeks does a better job detecting abnormal and potentially dangerous heart rhythms than the Holter monitor, which is typically used for 24 hours and has been the standard of care for more than 50 years.
The findings, which were published and made publically available online by the American Journal of Medicine today, suggest that the ZIO Service -- which includes the ZIO Patch, data analysis and a diagnostic report provided by device maker iRhythm Technologies of San Francisco -- could replace the Holter monitor as the preferred method of tracking electrical heart activity in ambulatory patients.
"This is the first large prospective validation that this new technology superseded the device invented by Norman Holter in 1949," said study senior author Eric Topol, M.D., a cardiologist who directs STSI and serves as the chief academic officer of Scripps Health. "By tracking every heart beat for up to two weeks, the ZIO Service proved to be significantly more sensitive than the standard Holter, which uses multiple wires and typically is only used or tolerated for 24 hours.
"For millions of people who present each year with suspected arrhythmia, this may prove to be the new standard for capturing the culprit heart rhythm electrical disturbance, most commonly atrial fibrillation which carries a significant risk of stroke," he said.
The ZIO Patch is a Food and Drug Administration-cleared compact, low-profile, noninvasive, water-resistant device that is worn for up to two weeks throughout normal activity then mailed by the patient to iRhythm for data analysis with a proprietary algorithm. The Holter monitor, which was first introduced in the 1940s, includes a cell-phone sized recorder typically worn at the waist and five to seven lead wires that attach to the chest.
