Miniature ECG data acquisition device

A system for recording a plurality of ECG traces, said system comprising

• an ECG acquisition device and a receiving processor;
• said ECG acquisition device comprising:
• a device having at least two outer surfaces and sized to be held on two of said at least two outer surfaces between two fingers of a first hand of a user, said device having a plurality of ECG electrodes on said at least two outer surfaces, a first of said two outer surfaces facing a first direction and a second of said two outer surfaces facing a second direction, said first direction different from said second direction;
• a controller;
• and
• circuitry that generates an ECG recording from signals of said plurality of ECG electrodes;
• said plurality of electrodes each being adapted to make electrical contact with the user's skin simultaneously at a plurality of respective locations on said user's body, each said electrode adapted to make electrical contact with a respective one of the plurality of locations on the user's body, said locations including both hands of the user;
• said controller being adapted to measure signals between said electrodes as a function of time, while the plurality of electrodes make electrical contact with the plurality of respective locations on the user's body;
• and
• said ECG acquisition device further comprising a circuit that generates a common mode cancellation signal injected through one of said plurality of electrodes;
• said receiving processor being configured to receive signals from said ECG acquisition device indicative of said measured signals, and to generate an ECG recording.
