Scott McTominay, the midfielder for Napoli, is set to have a minor heart procedure after being diagnosed with a "mild benign arrhythmia," the club confirmed. The 29-year-old was substituted after 56 minutes in Napoli’s 2-1 Serie A loss to Como on Sunday and is expected to receive treatment in the coming days. Napoli anticipates that McTominay will be back in action after the international break in early October. In a message on Instagram, he said, "See you soon Napoli. I won't take long." McTominay's absence may affect Scotland's upcoming matches under new head coach Sebastien Pocognoli. He is likely to miss the first four games of the Nations League, which include home and away fixtures against Slovenia, as well as matches against North Macedonia and Switzerland. These games are crucial for Scotland as they aim to build momentum under their new coach. An arrhythmia is a condition in which the heart beats too fast, too slow, or with an irregular rhythm, according to the NHS. While many cases are benign and may not cause serious issues, some can require medical intervention. McTominay’s condition is described as mild and benign, indicating that it is not life-threatening but may need correction to ensure normal heart function. Napoli has stated that McTominay will undergo a cardiac arrhythmia ablation, a procedure in which heat or cold energy is used to create small scars in the heart. This helps block faulty electrical signals that cause the irregular heartbeat, as explained by the British Heart Foundation. The procedure is commonly used to treat certain types of arrhythmias and is generally considered safe and effective. Following the treatment, McTominay is expected to make a full recovery and return to his club’s lineup soon.
