1. A system for treating cardiac arrhythmia, the system comprising:

  • a sensing lead configured to sense electrical signals attendant to the depolarization and repolarization of a heart;

    a processor configured to receive the electrical signals, to detect cardiac arrhythmia from the electrical signals, to discriminate between an atrial arrhythmia and a ventricular arrhythmia as a function of the electrical signals, and to generate an arrhythmia signal as a function of the type of arrhythmia discriminated from the electrical signals; and

    a drug delivery system configured to receive the arrhythmia signal, the drug delivery system comprising;

    a first drug pump containing a first drug;

    a second drug pump containing a second drug;

    a first infusion apparatus coupled to the first drug pump; and

    a second infusion apparatus coupled to the second drug pump, wherein the drug delivery system is configured to activate the first drug pump to dispense the first drug via the first infusion apparatus when the arrhythmia signal is indicative of atrial arrhythmia, and wherein the drug delivery system is configured to activate the second drug pump to dispense the second drug via the second infusion apparatus when the arrhythmia signal is indicative of ventricular arrhythmia.
