The ZIO Service detected two arrhythmias not captured by the Holter during the initial 24 hour period. An event monitor does not record continuously. Much of the clinical evidence has concluded that there is substantial clinical value in detecting abnormal cardiac. Holter monitors record continuously, usually for about 24 to 48 hours. Traditional 24 hour Holter monitoring has evolved substantially in recent years due to the advent of a wearable 3-14 day long term continuous monitoring or long term Holter monitoring patch. This is another portable device used to analyze the heart’s signaling.
An event monitor is very similar to something called a Holter monitor.
However, all of those arrhythmias were picked beyond 24 hours by the patch during the device’s extended monitoring period. A standard ECG only records the heart signal for a few seconds, and it is not portable. The Nuubo ECG Vest is in a class of its own being the only wearable ECG monitoring technology that continuously records & analyzes every single beat for a period of 3 days up to 30 days. One unexpected finding was that the Holter monitor detected 11 more arrhythmias than the ZIO Service during the initial 24 hour period when both devices were working simultaneously. is proud to introduce the industry’s first true 30-day wearable ambulatory ECG monitor called the Nuubo ECG Vest. A survey of study participants found that 81 percent of them preferred wearing the patch over the Holter monitor, with 76 percent saying the Holter monitor affected their daily living activities. Physicians who reviewed data from both devices reported reaching a definitive diagnosis 90 percent of the time when using the patch results and 64 percent of the time when using Holter monitor data. An arrhythmia event was defined to be 1 of 6 types: “supraventricular tachycardia (>4 beats, not including atrial fibrillation or flutter), atrial fibrillation/fluter (>4 beats), pause >3 seconds, atrioventricular block (Mobitz type II or third-degree atrivoventricular block), ventricular tachycardia (>4 beats), or polymorphic ventricular tachycardia/ventricular fibrillation”. They found that the ZIO Service detected 96 arrhythmia events, while the Holter monitor detected 61. In the current study, the researchers collected data from 146 patients who were equipped with both a Holter monitor for 24 hours, and a ZIO Patch for 2 weeks.
At the end of the 2 weeks, the patch must be sent back to iRhythm for a full analysis using the ZIO Service’s proprietary algorithms, and a diagnostic report is then relayed to the patient’s physician. It sports hydrogel electrodes for clearer ECG tracings and a button to capture symptomatic events. The FDA-cleared ZIO Patch is a small, adhesive, water-resistant one lead ECG sensor that the user can stick onto their chest for a continuous 24-hour monitoring over 2 weeks.
