"I was brushing my teeth when there was a banging on my door and there were all these nurses with jump leads ready," said Mr Stannett. "I stood there with foam around my mouth and said 'god, they think I'm having a heart attack or a fit'. "As soon as I said 'I'm brushing my teeth' you could see the change in the people's expressions, just sheer relief followed by raucous laughter. I want to thank the staff at Yeovil for their absolute professionalism and their dedication," he added. The nurses told Mr Stannett the toothbrush had sent a signal from his heart monitor to the coronary care unit monitor which had gone "off the screen".
