Abstract

A method of treating cardiac arrhythmias resulting from errant electrical signals conducted through the cardiac tissue from a source location. The magnitude of the errant signals is reduced by shunting electrical signals from the source location with an electrically conductive element having a sufficiently low impedance.

Claims

1. A method of treating cardiac arrhythmias resulting from errant electrical signals conducted through the cardiac tissue from a source location in the heart, the method comprising reducing the magnitude of the errant signals by shunting electrical signals from the source location to at least one location that reduces the errant electrical signals and establishes a normal heartbeat with an electrically conductive element having a sufficiently low impedance introduced into the body.

2. A method of treating cardiac arrhythmias resulting from errant electrical signals conducted through the cardiac tissue from a source location in the heart, the method comprising shunting electrical signals from the source location to at least one location that reduces the errant electrical signals and establishes a normal heartbeat with an electrically conductive element introduced into the body having an impedance sufficiently low to reduce the errant electrical signals conducted through the cardiac tissue.

3. The method according to claim 2 wherein the electrically conductive element is connected between the source location and at least one location where the electrical signal conducted by the element does not interfere with the rhythm of the beating heart.

4. The method according to claim 3 further comprising applying a pacing signal to the heart to replace the shunted signal and establish a substantially normal beating rhythm.

5. The method according to claim 2 wherein the electrically conductive element is connected between the source location and at least one location where the electrical signal conducted by the element establishes a normal beating rhythm.

6. The method according to claim 2 wherein the conductive element has threaded anchors threaded into the cardiac tissue.

7. A method of treating cardiac arrhythmias resulting from errant electrical signals conducted through the cardiac tissue from a source location in the heart, the method comprising securing one end of an electrically conductive element to the source location, and contacting the other end of the electrically conductive element introduced into the body to a plurality of locations on the surface of the heart until a location is found that reduces the errant electrical signals and establishes a normal heart beat;

and securing the second end of the element to the location that reduces the errant electrical signals and establishes a normal heart beat.

8. A method of treating cardiac arrhythmias resulting from errant electrical signals conducted through the cardiac tissue from a source location in the heart, the method comprising securing one end of a electrically conductive multi-branched element introduced into the body to the source location, and securing the end of each of the branches to locations on the surface of the heart to shunt the errant signals.

9. The method according to claim 8 wherein the branches of the electrically conductive element are connected to locations where the electrical signal conducted by the element does not interfere with the rhythm of the beating heart.

10. The method according to claim 9 further comprising applying a pacing signal to the heart to replace a shunted errant signal and establish a substantially normal beating rhythm.

11. The method according to claim 8 wherein the branches of the electrically conductive element are connected to locations where the electrical signal conducted by the element establishes a normal beating rhythm.
