BRONNY IS RECOVERING FROM CARDIAC ARREST. GOOD AFTERNOON TO YOU. I'M JEFF HOGAN. >> AND I'M RENEE CHOU. THANKS FOR JOINING US. BRONNY IS 18 YEARS OLD. HE WAS AT BASKETBALL PRACTICE AT USC WHEN THIS HAPPENED. MICHELLE MACKONOCHIE IS IN THE WRAL LIVE CENTER WITH A STATEMENT FROM HIS FAMILY. YEAH, JUST SUCH SCARY NEWS. HE IS ONLY 18 YEARS OLD, BUT HE WAS AT A WORKOUT AT USC YESTERDAY. THAT IS WHEN HE SUFFERED THE CARDIAC ARREST. ONLY 18 YEARS THE SOUTHERN UNIVERSITY OF SOUTHERN CALIFORNIA FOR A FRESHMAN. >> WAS JUROR AT A WORKOUT. BUT HIS FAMILY DID RELEASE A STATEMENT THIS AFTERNOON SAYING YESTERDAY WHILE PRACTICING BRONNY JAMES SUFFERED A CARDIAC ARREST, MEDICAL STAFF WAS ABLE TO TREAT BROADY AND TAKEN TO THE HOSPITAL. HE IS NOW IN STABLE CONDITION AND NO LONGER IN THE ICU. LEBRON AND SAVANNAH WISH TO PUBLICLY SEND THEIR DEEPEST THANKS AND APPRECIATION TO THE USC MEDICAL AND ATHLETIC STAFF FOR THEIR INCREDIBLE WORK AND DEDICATION TO THE SAFETY OF THEIR ATHLETES. AGAIN, HE IS IN STABLE CONDITION TODAY. THIS ALL HAPPENED YESTERDAY EVENING DURING A PRACTICE. BUT JUST SO SCARY. HE'S ONLY 18 YEARS OLD. >> JOE, THANKS FOR THAT. TO TAKE THIS ONE STEP FURTHER WITH DOCTOR CHRISTOPHER KELLY. A CARDIOLOGIST WITH UNC HEALTH DOCTOR. KELLY, THANK YOU SO MUCH FOR JOINING US RIGHT NOW WITH SOME THOUGHTS ON WHAT LITTLE WE KNOW ABOUT THE CIRCUMSTANCES AROUND BROWNING'S CARDIAC ARREST. THE FIRST THOUGHT I'M SURE CAME INTO A LOT OF FOLKS MIGHT DAMAR HAMLIN. IT WAS INJURED FOR THE BUFFALO BILLS ON THE FOOTBALL FIELD WITH A DIRECT HIT TO THE CHEST. WHAT DO YOU THINK OF WHEN YOU HEAR CARDIAC ARREST IN AN ATHLETE? >> ASIA. YES, AND THANKS FOR HAVING ME ON TO TALK ABOUT THIS. OBVIOUSLY, EVERY PARENT'S WORST NIGHTMARE TO HAVE THEIR CHILD HAVE SOMETHING LIKE THIS. AND FOR EVERY ATHLETE IS OBVIOUSLY A TERRIFYING PROSPECT THAT THIS COULD HAPPEN. >> SO THERE'S THERE'S 2 SORT OF >> BROAD POSSIBILITIES HERE. ONE IS THAT THERE'S SOME UNDIAGNOSED HEART THAT BECOMES A, YOU KNOW, MANIFEST DURING EXERCISE AND CAN CAUSE CARDIAC ARREST, WHICH IS STOPPING OF THE HEART MUSCLE, WHICH IS DEFINITELY ARE RESUSCITATED. AND THEN THERE'S ALSO SOMETHING THAT HAPPENS TO A OTHERWISE HEALTHY PERCENT ON THE FIELD LIKE DAMAR HAMLIN WHO HAD AS FAR AS WE KNOW, NO PREEXISTING HEART PROBLEMS BUT JUST GOT HIT IN THE CHEST PART ABOUT THAN JUST THE WRONG TIME. WE KNOW ABSOLUTELY NOTHING ABOUT WHAT HAPPENED. MISTER JAMES. THAT HE HAS A VERY FAST RECOVERY AND WE HOPE THAT IS ALSO SPURS A DISCUSSION KEEPING ATHLETES SAFE. >> WHAT DOES IT MEAN IN GENERAL TERMS, THE FACT THAT HE WENT INTO ICU CAME OUT OF ICU QUITE QUICKLY. WHAT DOES THAT MEAN FOR HIS RECOVERY? >> YES, SO YOU GET YOUNG PEOPLE WHO EXPERIENCE CARDIAC ARREST. IF THEY ARE PROMPTLY RESUSCITATED WITH CPR AND DEFIBRILLATOR GENERALLY DO WELL, THEY WILL ALWAYS GO TO THE ICU FOR AN INITIAL PERIOD OF BUT AS LONG AS CPR WAS STARTED RIGHT AWAY, THAT USUALLY RECOVER NICELY. AND THANKFULLY, THAT'S WHAT WE SAW WITH MISTER HAMMOND. SOME I'M HOPEFUL THAT THE NEWS THAT HE'S ALREADY OUT OF THE ICU MEANS THAT MISTER JAMES WILL HAVE A QUICK RECOVERY AND BE BACK ON VARIOUS HIM. HE'S 18 YEARS OLD AND A LOT OF ATHLETES WILL BE HEADED BACK TO SCHOOL AND BE ON OUR FIELDS AND COURTS HERE BY THE THOUSANDS. >> ARE THERE THINGS THAT PARENTS AND THOSE ATHLETES SHOULD BE CONCERNED ABOUT? CAN SCREENING OF COMPETITIVE ATHLETES FOR UNDERLYING HEART CONDITIONS IS ACTUALLY A SOMEWHAT CONTROVERSIAL SUBJECT IN MEDICINE. AND THERE'S A LOT OF DIFFERENT PRACTICES FROM ONE DOCTOR TO AN EXIT FROM ONE COUNTRY TO ANOTHER. >> SOME COUNTRIES, 2 VERY AGGRESSIVE SCREENING OF ALL HIGH SCHOOL IN OLDER ATHLETES WITH EKG AND HEART TESTS BEFORE THEY COMPETE. OTHER COUNTRIES DON'T DO ANYTHING. AND THE U.S. IS SOMEWHERE IN THE MIDDLE WHERE DEPENDING ON WHICH DOCTOR YOU SEE, YOU MAY GET A MORE OR LESS THOROUGH EXAM. WE DO RECOMMEND IS CARDIOLOGIST THAT YOU KNOW, FROM MIDDLE SCHOOL ONWARDS COME ENGAGING IN COMPETITIVE SPORTS, UNDERGO A HISTORY OF PHYSICAL WITH THEIR PEDIATRICIAN OR A DOCTOR, WHICH INCLUDES A LOT OF QUESTIONS TRYING TO ELICIT ANY UNDERLYING HEART WHETHER OR NOT YOU ALSO DO HEART TEST LIKE AN EKG WHERE THEY MEASURE THE ELECTRICAL SIGNALS FROM THE HEART OR AN ULTRA SOUND WHERE THEY ACTUALLY LOOK AT THE HAR WILL DEPEND A LOT. AT WHAT LEVEL YOU'RE COMPETING AT WHAT DOCTOR YOU SEE PRO ATHLETES GET THE WORKS. YOU KNOW, MIDDLE SCHOOL STUDENTS GET BASIC EXAMINE. EVERYONE ELSE IS SOMEWHERE IN BETWEEN. >> GOT IT. DOCTOR CHRISTOPHER KELLY, THANK YOU SO MUCH FOR THOSE INSIGHTS. I KNOW OUR
