12 LEAD 24 HOURS HOLTER SYSTEM This product is based on 3 lead system combined with the most advanced international electronic technology. The FLASH MEMORY with super-storage capacity applied in the recorder really realizes 12 lead 24 hours continuous synchronous non-compression recording. It ensures the reliability and the high precision of the recording. It?s more exact than 3 lead system in diagnosing arrhythmia, hypertrophy of myocardium and locating and quantifying the lack of blood in the coronary arteries, so it has much better clinical application. 12 lead Holter-star system also has multi-function include HRV, QTD, and QTC besides common arrhythmia and ST segment analysis. In addition, the methods of time domain, frequency domain and non-line HRV analysis meet the international standard.
