A new study by the American Heart Association shows more Americans are living with pacemakers than ever before.
The use of pacemakers has gone up 50 percent in the last decade, according to the study.
"My chances of even being here are so small that it has to be a miracle. That's all it can be, is God's miracle," said Les Johnson from Delavan.
His wife, Kitty, said that Les collapsed after a morning run last August.
"I heard this thud, I turned around and he was lying flat out on the brick walkway," Kitty Johnson said.
One the most common heart problems is an irregular heartbeat. Dr. Tom Teelin, a cardiologist with Mercy Health System who specializes in studying heart rhythms, said a pacemaker can be a good alternative to open heart surgery.
"Les was really doing everything a physician would want their patient to do -- dieting, he was exercising," said Teelin.
