Viatom Checkme Pro

Has anybody else used this monitor? I bought it so I could email ecg recordings to the Cardiology clinic. It will take 24hr single lead holter readings. It can be used with wired skin contacts or direct skin contacts. It can also take overnight SPO2 recordings. The best feature is that it measures the QTc interval so my Sotalol can be monitored at home. It does cost £350 but the holter monitors used in the NHS cost £2000. The EP consultant accepted the QTc readings as accurate enough to monitor the effect of Sotalol on PVCs and the QTc interval.
