The procedure takes around 10 minutes in an outpatient clinic setting and does not require an inpatient admission. The implant device is then injected, rather than requiring a larger operation. To implant the device, the consultant will make a very small incision superficially in the skin on your chest (less than 1cm). This is because the problems they encounter come and go and may not be present at the time of the initial clinical assessments. It is not uncommon for people with these symptoms to present to various health care professionals and their initial investigations are normal. There are therefore a wide range of patients that can benefit from this type of investigation. Close monitoring offers the ability to diagnose people who have abnormal heart rhythm problems, which present intermittently and can otherwise be difficult to detect.Ĭhanges in heart rhythm can sometimes lead to unexplained falls, dizziness, palpitations, shortness of breath, chest pain, seizures and - on occasion - strokes. The device then allows us to continuously monitor your heart rhythm for up to three years. Advanced technology has allowed the development of a very small implantable device which is easily placed under the skin. 2016 27:1403‐1410.Dr Jeremy Butts, Consultant Cardiologist introduces to Spire Elland Hospital a new cardiac monitoring system.Īccurate information is the key to better healthcare.

The accuracy of arrhythmia detection in both ICMs remains suboptimal.Ītrial fibrillation cryptogenic stroke implantable cardiac monitor remote monitoring syncope. Patient-averaged true positive detection rates were not statistically significant in the two groups (Reveal LINQ vs Confirm Rx, AF: 52% vs 38% bradycardia: 67% vs 59% pause: 24% vs 20% tachycardia: 81% vs 94%).Ĭompared to the Reveal LINQ, Confirm Rx has shorter event transmission time, more frequent event detections, shorter duration to diagnose true arrhythmic events, and higher percentage of diagnosed patients. Kaplan-Meier analysis showed that the Confirm Rx group detected true arrhythmic episodes sooner with higher percentage of diagnosed patients during 6-month follow-up (P =. 01), which is likely due to event transmission setting differences between the two groups. The total number of events was also higher in the Confirm Rx group (25.5 ± 45.6 vs 0.9 ± 1.1 events per patient-month, P <. 0001) was significantly shorter in the Confirm Rx group. ![]() 02) and for patient activated triggers (24 ± 103 vs 475 ± 426 minutes, P <.

Data transmission time is defined as the time from event occurrence to physician notification. Arrhythmic events include atrial fibrillation (AF), pauses, and bradycardia. In this prospective study, 142 patients were randomized 1:1 to receive Reveal LINQ or Confirm Rx ICM system. The objective of this study was to compare the efficiency of data transmission and arrhythmia detection accuracy of the Reveal LINQ with TruRhythm Detection with the Confirm Rx with SharpSense Technology. However, the data transmission time and accuracy of detecting cardiac arrhythmias are unclear. Implantable cardiac monitors (ICMs) are increasingly used to detect arrhythmias in various clinical situations.
