The CardioCall VS20 can be used as a “loop” recorder, using chest electrodes, or as an event unit. It features 20 minutes of programmable memory and runs on a single AA battery. The ECG may be sent trans-telephonically to a receiving station or downloaded directly onto your PC.
The CardioCall ST80 has an 85-minute programmable memory, for use in patients with more severe syncope episodes. Both offer single- or dual-channel ECG.
