When Rick Edmund conquered the hike up a butte in South Dakota’s Custer State Park with his granddaughter last year, he had a big smile on his face and offered a huge shoutout.

Edmund, 75, pastor of Chapman Quarries United Methodist Church, 1433 Main St., Bath, recorded thank you videos to Steven Stevens, M.D., FHRS, and James Gallagher, M.D., of St. Luke’s Cardiology Associates.

If not for their care, Edmund said, he may have never made that climb in Custer State Park - or any of the other climbs, as he and granddaughter Elisabeth trekked through North Dakota and South Dakota, visiting several national parks.

Edmund was trying to live with persistent atrial fibrillation (AFIB) that was robbing him of his active lifestyle last year. Before that, he had been an active hiker and walker and had been working out at two gyms. Those activities went by the wayside as he had trouble catching his breath while struggling to climb the church steps.

He has had lifelong blood pressure issues - for which he was on medication - but nothing prepared him for the struggle to breathe during activity that started last spring.

When he told his primary care physician of his struggles, she referred him to Dr. Gallagher, who examined Edmund and referred him to Dr. Stevens, director of Cardiac Electrophysiology-Device and Ambulatory Service Lines for St. Luke’s University Health Network, for an ablation.

An ablation is used to correct the electrical signals that cause the heart to go into AFIB or other heart arrhythmias. The electrophysiologist will run the catheter to the heart from veins in a patient’s leg.

“Mapping” is done when a 3D model of the heart is generated from those catheters and locates the abnormal electrical activity that is triggering the arrhythmias.

“Mapping is GPS for the heart,” Stevens said.

For AFIB, the most common culprit area is from the pulmonary veins, and the procedure is called pulmonary vein isolation. The catheter tip then heats up or freezes to create a small amount of scar tissue and stops that area from firing inappropriately, allowing the heart’s electrical system to work properly again.

“Rick is a really good guy and very interesting,” Dr. Stevens said. “He had persistent AFIB, which means he was in it all the time. He was symptomatic, and it affected his lifestyle.”

Edmund went back into AFIB three days after the ablation, and Stevens knew something else had to be done, as it is relatively common for AFIB to recur transiently early after an ablation.

“We did a cardioversion for Rick,” Stevens said. “It’s like a reset for the heart, not a cure for AFIB.”

Cardioversion uses external electrodes to send mild shocks to the heart and return it to a normal rhythm.

“The ablation fixed the arrhythmia, and the cardioversion just reset the heart,” Stevens said. “This wasn’t unexpected or a complication. If we didn’t do the ablation, just the cardioversion, the heart couldn’t hold the normal rhythm like it does now and he would be going back into AFIB.”

“I recovered from that one right away,” Edmund said. “I came out of it and have felt pretty good ever since.”

He has been hiking every week, heading frequently to Jacobsburg Park in Northampton County. He is very much enjoying being active again, he said, and is especially proud of his performance on a stairclimbing machine - chalking up 180 flights in 30 minutes.

“The World Trade Center was 110 flights,” he said. “Make sure Dr. Stevens and Dr. Gallagher know I did that.”
