MONTGOMERY, Ala. (AP) — Doctors performed a cardiac procedure on Alabama Gov. Robert Bentley on Wednesday after he was hospitalized for an irregular heartbeat. His office later said he was going home and back to work.

Bentley, 74, was admitted to Baptist Medical Center South with atrial fibrillation, according to a statement released by his office from Tiffany Bass, director of cardiovascular services at the hospital.

His normal heart rhythm was restored with a transesophageal echocardiogram and cardioversion procedure, the statement said. An echocardiogram is used to check for blood clots, and cardioversion involves a shock to reset the heart, according to the American Heart Association.

Untreated, an irregular heartbeat can increase the risk of stroke and heart failure. But the governor’s spokeswoman, Yasamie August, issued a statement saying Bentley “is feeling well and there are no serious medical concerns.”

Around lunchtime, the governor’s office tweeted a photo of Bentley with a hospital worker and the message: “Thanks for the great care from doctors & nurses. God bless you all for your prayers, texts & phone calls. Headed home, getting back to work!”

In an interview, August said the governor began feeling unwell early Wednesday and went to an emergency room, where doctors diagnosed a previously undetected heart arrhythmia.

Bentley appeared fine Tuesday night at a legislative reception hosted by the state’s seafood industry, according to legislators and others who were there.

The second-term governor still faces the threat of impeachment after a scandal involving his relationship with a former aide. The House Judiciary Committee on Wednesday directed its special counsel to resume an investigation, but does not have plans at this time to hold any public hearings.

The House probe was paused in November at Attorney General Luther Strange’s request before Bentley promoted Strange to the U.S. Senate to replace Jeff Sessions. Strange’s replacement then recused himself. The Attorney General’s investigation continues under a retired district attorney.
