Cardiac arrhythmia treatment methods
Disclosed are methods of preventing or treating cardiac arrhythmia. In one embodiment, the methods include administering to an amount of at least one polynucleotide that modulates an electrical property of the heart. The methods have a wide variety of important uses including treating cardiac arrhythmia.
1. A unitary catheter drug delivery device having a proximal end and a distal end, said device comprising in combination:
an apparatus for delivery of a polynucleotide to a patient;
a reservoir housing a polynucleotide encoding a human protein selected from the group consisting of: a wild-type inhibitory Gα i2 protein subunit, and a constitutively active Gα i2 subunit;
an apparatus for detection of position of the device within the patient: and
electrodes for detecting position of the distal end.
2. The device of claim 1 wherein the device is adapted for an endoscopic procedure.
