Sonny Colbrelli will be able to leave the cardiac ward in Girona and return to Italy within the next few days as doctors determine the cause of his unstable arrhythmia after the first stage of the Volta a Catalunya and investigate its long-term impact on his racing career.

Colbrelli's wife Adelina, father Luca, and agent Luca Mazzanti arrived in Spain today, and La Gazzetta dello Sport reports that they will be able to return by the weekend.

Colbrelli has been active on social media during his hospitalization and, according to the paper, remembers little of what happened. He was initially optimistic about an early return to racing, but after suffering an unstable arrhythmia and doctors confirmed that he had restarted his heart with a defibrillator, both he and his doctors are cautious.

"If he had had a heart attack in training and there was no doctor and especially no defibrillator nearby, Colbrelli could have died," Alex Flor Costa, the race doctor for the Volta a Catalunya, told the Spanish newspaper El Periodico. He suggested.

"I think he was lucky, but I don't want it to end like this. ......"

La Gazzetta dello Sport quoted Colbrelli as saying on Wednesday.

According to Bahrain Victorious, initial tests did not show any signs of anxiety or loss of function in Colbrelli's heart, but his future as a professional rider remains uncertain.

On Tuesday, the Bahrain Victorias team confirmed that Colbrelli will use a defibrillator after suffering an unstable arrhythmia.

He confirmed that the Garmin bike computer did not show abnormal heart rate data before Colbrelli fell to the ground, but was cautious about Colbrelli's recovery and future.

"We are on the first page of a book yet to be written. We are going to turn it one page at a time," Zaccaria told Tuttobiciweb.

La Gazzetta dello Sport spoke with Ramon Burgada, head of the cardiology department at the Girona Hospital. He suggested that the cause of Colbrelli's collapse could be either a genetic problem, a blockage in a coronary artery, or a problem related to the intensity of racing or training.

Colbrelli will now undergo a heart scan, a cardiac angiogram, and more genetic testing, but it will take several weeks to know the full results. He will also undergo further tests upon his return to Italy.

Brugada was cautious about predicting whether the incident would affect Colbrelli's racing career.

"Every patient is different, but we must accept that his heart called for a stop and listen to its signals," the Catalan doctor said.

"I know it is difficult for an athlete to move from a race to a hospital bed, but it is important to understand and accept the reality of what happened.

"We have to protect people's health by informing them of all aspects. What to do after that is up to the people involved, their families, and the team. Some players have been able to continue, others have been interrupted. The situation is still unpredictable."[29
