Heather Hendershot was watching TV with her husband one night when her smart watch buzzed with an alert. It said her heart rate was over 120.

She felt fine and thought a good night’s sleep would lower it. 

“I couldn’t feel it going fast,” Hendershot said. “I couldn’t feel it beating hard.” 

The next morning her watch indicated her heart rate was still too fast. She said she was worried she might be fighting an infection that could spread to her young children. She decided to have it checked out.

An urgent care doctor was unable to determine what was causing her heart to beat so quickly. They sent her to the emergency room at Stormont Vail.

“They did some lab work, gave me some IV fluid and then with the lab work they noticed my thyroid was out of whack,” Hendershot said.

She was diagnosed with thyroid storm. 

“I had no idea that even existed, but it can be fatal if left untreated,” she said. 

Her husband said what they thought was the flu was something potentially far worse. 

“Come to find out it could be a life threatening thing,” Cody Hendershot said. “So, the watch kind of saved her life when you find that out.” 

Now she says she keeps her watch on day and night, “I will not take it off.”

Hendershot said she didn’t think she’d need the heart rate monitor when she bought the watch, but she’s glad she has it. And now her husband and aunt are planning on getting smart watches as well.
