This EVO digital recorder uses a readout system that is similar to what a Holter system uses but is extremely easy to use as it weighs 2.5 ounces and is easy to place under clothing. The ECG display shows signals in real time and can be recorded for forty-eight hours. The pacer detection system is always on as well. The device can also be recharged as data is loaded into it through a Dynamic Energy Source docking station that comes with it. There are no batteries, memory cards or tough parts, thus making this easier to maintain. Also, the lack of individual lead wires makes it easier for this product to be maintained as necessary.
