UNION COUNTY, N.C. -- Tim Blanchard, of Monroe, knew his heart was beating irregularly. Doctors with Carolina HealthCare System found a blood clot and treated it before sending him home.

Knowing his heart wasn't at full strength his team recommended he wear a 'Zoll Life Vest,' a sort of wearable automated external defibrillator. Zoll is the name of the company that makes it.

"I looked up and that's the last thing I remember," Blanchard said, describing falling to the floor as he went into full cardiac arrest. "There's not even a split second warning."

The vest shocked his heart back into action. After Tim was rushed into the hospital doctors implanted a cardioverter defibrillator to keep his heart in normal rhythm.

"The electrical system of the heart goes haywire- which can be deadly within minutes," explained Dr. Jens Eichhorn, a Cardiologist with Sanger Heart and Vascular Institute. "Every minute counts. Usually, help comes too late. He survived which is a miracle."

Tim is looking forward to celebrating his anniversary with his wife soon.
