Halifax RLFC is the first in its championship to test players hearts in a preventative campaign against sudden cardiac arrest.
All super league rugby clubs carry out a electrocardiogram (ECG) test on players. But championship clubs do not test for electrical activity of the heart.
Halifax RLFC rugby player and Heartbeat of Sport employee Tony Tonks organised screenings for players at the Shay stadium.
The heart disease test tracks and traces heart rhythm problems and the conduction of the heart beat.
Testing was done by Cardiac Risk in the Young - heart screening for 14-35 year-olds.
Mr Tonks said: “Halifax is the first champions hip club to be tested. Heartbeat of Sport would like to take this further in the future to make sure every semi-professional club and amateur clubs get the chance to have the easy and simple test that takes just five minutes. This can save sportsmen and women’s lives, who are at a greater risk of cardiac problems.”
Player Ricky Sheriffe was found to have minor irregularity which will now be monitored.
Halifax RLFC and 20 fans did a sponsored Three Peak Challenge and raised £3,500 to cover the cost of the test.
