    There are single lead devices that works in conjunction with a smart phone.

    eg. KardiaMobile -



    Also there are Hospital grade 8/12 lead ECG devices that works with Smartphones but quite expensive.

    thanks machan..is this graph same as the hand pulse graph
    These graphs can differ because of the phase lag obviously. But KardiaMobile and many other diagnostic devices uses custom algorithms to get a higher degree of accuracy to the true values. The accuracy of the KardiaMobile algorithm measured independently is quoted as sensitivity of 88% (95% CI 32.3%-99.1%) and a specificity of 97.2% (95% CI 95.1%-98.5%)

    If you have surface electrodes, you can just attach to the chest area and use a simple data acquisition device to get a graphical display on a computer.
