Emergency Response Inside the Cage
Norbert Bidrman, Oktagon MMA’s chief medic, described the emergency situation in a statement posted on social media. He said the medical team acted quickly when Janecka collapsed.
“We just had a very emergency situation here, where one of the fighters, specifically Jindra, went into a sudden cardiac arrest,” Bidrman said. “After some cardiopulmonary resuscitation, we delivered a shock.”
The medical staff gave Janecka oxygen as part of the resuscitation effort. He regained consciousness while still inside the cage.
Bidrman said Janecka was able to communicate with the medical team before paramedics arrived. “He is fully oriented to place, time, and person,” the chief medic stated.
BRNO ambulance service transported Janecka to the hospital. Bidrman thanked the ambulance team for their quick response.
Possible Cause Under Investigation
Bidrman said the medical team believes a blow to the chest may have caused the cardiac arrest. The impact could have triggered an irregular heart rhythm called arrhythmia.
“Most likely this could have been some kind of arrhythmia caused by a blow to the chest that he received earlier,” Bidrman explained. However, he said the exact cause has not been confirmed.
The medical team will investigate what happened to Janecka. “Now we just want to find the cause of why this happened,” Bidrman said.
Janecka was already conscious when he arrived at the hospital. He had been able to speak with doctors at the cage before the ambulance took him away.
The Oktagon MMA promotion released Bidrman’s statement on X (formerly Twitter) shortly after the incident. The statement confirmed that Janecka was conscious and communicating before leaving the venue.
This type of cardiac event is rare in combat sports. Commotio cordis, a condition where a blow to the chest causes sudden cardiac arrest, can occur when impact happens at a specific moment in the heart’s rhythm.
The medical team at Cage Game 2 had emergency equipment ready at cageside. Their quick response with CPR and the defibrillator saved Janecka’s life.
Bidrman confirmed that Janecka was fully conscious in the cage after being revived. The fighter was able to communicate with the medical staff before paramedics took over his care.
