Cardiac Arrest While Walking: Michael McKee’s Survival Story
Written by Pearl Salkin
Updated September 2026 to reflect current CPR and post-cardiac-arrest guidance.
Walking to work is usually considered one of the healthier ways to start the day.
For 58-year-old Minneapolis resident Michael McKee, however, cardiac arrest while walking to work nearly ended his life in 2008.
McKee was on his usual four-mile route along the Mississippi River when he collapsed without warning.
He had some known cardiovascular risk factors, including high blood pressure, elevated cholesterol, and a family history of heart disease.
But he had no reason to expect that an ordinary walk to work would turn into a sudden cardiac arrest emergency.
Cardiac Arrest While Walking Came Without Warning
McKee has no memory of what happened that morning.
He later learned that he had collapsed along his route and may have been on the ground for some time before help arrived.
Two people were already nearby when a physician riding a bicycle noticed the situation, stopped, and began CPR.
Another nearby resident went into his home and returned with a houseguest who was also a physician.
Together, the rescuers continued working to keep McKee alive until emergency medical personnel arrived.
Bystander CPR Helped After His Cardiac Arrest While Walking
When EMS reached McKee, rescuers used a defibrillator several times in an effort to restore an effective heart rhythm.
He was then transported to Hennepin County Medical Center in Minneapolis.
That sequence remains central to modern cardiac-arrest care:
Recognize cardiac arrest. Call 911. Start CPR. Use an AED or defibrillator as soon as possible.
The American Heart Association continues to emphasize high-quality CPR and prompt defibrillation as key early interventions that can improve survival from adult cardiac arrest.
For McKee, the people who stopped and started CPR helped bridge the gap between his collapse and the arrival of professional emergency care.
Post-Cardiac-Arrest Cooling Has Changed Since 2008
McKee received what was then commonly called therapeutic hypothermia, in which doctors intentionally lowered body temperature after cardiac arrest to help protect the brain.
The science has evolved since then.
Current American Heart Association guidance recommends a controlled temperature-management strategy for adults who remain unresponsive after circulation returns.
Recommended temperature control ranges from 32°C to 37.5°C and should generally continue for at least 36 hours when appropriate.
This is specialized hospital care.
For bystanders, the priorities are much simpler:
Call 911. Start CPR. Use an AED if available.
Bystanders should not attempt to cool someone with ice or cold packs during cardiac arrest unless directed by medical professionals.
A Stent Addressed a Heart Blockage
McKee spent more than a week in the hospital.
According to the original account, doctors identified a coronary blockage and treated it with a stent, a small device placed inside an artery to help restore blood flow.
After leaving the hospital, McKee made changes to his diet and followed the medication plan prescribed by his cardiologist.
Within about six weeks, he had returned to work and was again walking several miles a day.
For someone who had experienced cardiac arrest while walking to work only weeks earlier, that recovery was remarkable.
A Chain of People Made the Difference
One of the most striking parts of McKee’s story is how many people played a role.
A passerby recognized that something was wrong.
A physician stopped his bicycle and began CPR.
Another physician came to help.
EMS provided defibrillation and advanced treatment.
Hospital teams continued his care.
No single link worked alone.
That is exactly why the American Heart Association continues to emphasize the Chain of Survival during cardiac arrest.
Early recognition, CPR, defibrillation, advanced care, and post-cardiac-arrest treatment all work together.
Why Bystander CPR Matters
McKee’s story carries an important message:
Do not assume someone else will act.
If an adult is unresponsive and not breathing normally, call 911 and begin CPR.
You do not need to be a physician.
You do not need to know exactly why the person’s heart stopped.
You simply need to recognize the emergency and begin helping.
CPR buys time.
An AED may restore a shockable rhythm.
And those few minutes can be the difference between life and death.
Cardiac Arrest Can Happen During Ordinary Activities
Sudden cardiac arrest does not only happen during intense exercise or obvious medical emergencies.
It can happen:
- While walking
- At work
- At home
- At the gym
- At church
- While shopping
- During recreational activities
That unpredictability is one reason CPR training is so valuable.
The person who needs help may be a stranger.
Or it may be someone you know.

You may never expect to encounter cardiac arrest while walking, commuting, exercising, or simply going about your day.
Neither did Michael McKee.
