A grandmother from Middlesbrough is the first woman in the world (outside of a clinical trial) to benefit from a new type of wireless pacemaker - that is just the size of a grain of rice.
71-year-old Joan Smith, from Marton, was diagnosed with cardiomyopathy 21 years ago.
She says she has never let her illness get in the way of living life to the full, with husband Alan and her five grandchildren keeping her busy.
Following two unsuccessful attempts at fitting a conventional pacemaker, Joan was referred to consultant cardiologist Dr Simon James to find out more about the new wireless pacemaker.
I felt a lot fitter straight away.
For Joan, as soon as the device was switched on there was a huge change in the pumping of the heart.
HOW DOES IT WORK?
The new tiny wireless pacemaker is implanted directly into the innermost layer of tissue that lines the left chamber of the heart, where it is most beneficial.
This can then perform the same job as a traditional CRT pacemaker - controlling abnormal heart rhythms using low-energy electrical pulses to prompt the heart to beat at a normal rate - but without the need for wires and the risk of complications that come with them.
