mHolter

How does the device work?

mHolter is a biomedical application for smartphones connected to skin electrodes, whose purpose is to monitor heart activity for 24 hours and record any abnormalities. It's a noninvasive product for all ages, and indicated for the control of various symptoms, from feelings of faintness to severe disease. The data collected on the phone will be processed by a server and the consequent electrocardiogram will be sent directly to the patient or analysed by expert cardiologists affiliated with mHolter. The system needs: • Skin electrodes: already present in the market • Electrodes/smartphone connector • Smartphone app: simple electrical input recorder • Server elaboration software: already present in current ECG machines Potential issues: • Smartphone battery lifetime: the smartphone just records the data and does not elaborate it, requesting few battery consumption • mHolter accuracy: the smartphone is just a bridge between electrodes and the elaboration unit. The accuracy will not change respect to current holter systems.

How will it impact healthcare?

Current standard holters offered by hospitals are sophisticated and expensive devices. Patients receive them after wait times that may extend several months. Since hospitals don’t carry many holters, patients can obtain this device just few times and hope that a cardiac event occurs during one of these holter tests. Advantages of mHolter:

  •  Cheap: the raw materials consist of just some electrodes, electrical cable and connector. Heart patients owning a smartphone compatible with mHolter can afford this reasonable price. mHolter may be intended also for hospitals in developing countries that do not have enough funding to buy standard holters.
  •  Repeatable: more times holter test is repeated, higher is the probability to obtain useful information to diagnose the heart’s disease with high accuracy
  • Easy-to-use: standard people are more able to handle a smartphone than a medical device
