"The heart rate of Philadelphia Flyers forward Scott Hartnell(notes) was elevated between the second and third periods of the team's Friday preseason game against the Detroit Red Wings, so the 29-year-old will be visiting a cardiologist on Tuesday, according to NHL.com.

The uptick was discovered after Hartnell had an abnormal twitching of his right arm between periods, the site notes. "He had a little bit of an elevated heart rate that would not go down even after rest during the intermission," GM Paul Holmgren said, according to the site. "We're getting him checked out. I'm sure it was a scary situation for Scott. We're mildly concerned because he is a young guy.""
