"gabapentin eliminated almost all the pain i have had for eight years due to a staph infection from heart surgery. however, after a few days i developed an irregular heartbeat and had to quit taking it. i called my doctor who said the gabapentin could not cause the irregular heartbeat, so i started taking it again. it worked wonders for the pain, but after a few days the irregular heartbeat reappears. i would love to be able to take gabapentin because it is a great pain reliever but i can&#039;t deal with the irregular heartbeat."
