Summary

Some patients with heart failure require treatment called cardiac-resynchronisation therapy (CRT) which involves putting a pacemaker into the heart to make both ventricles (the lower chambers of the heart) contract together, making the pumping of the blood to the rest of the body more efficient.

it is important to get the CRT pacemaker checked to make sure that it is working correctly and performing its job. However, it can be difficult to adjust the settings of the pacemaker just the right amount to ensure the heart is pumping efficiently.

One of the ways this can be done is by using a special machine which uses ultrasound to make a 2-dimensional image of the heart called an echocardiogram. This technique can also be used to measure the flow of blood in the heart and calculate how efficient it is at pumping blood. However adjusting the settings of the pacemaker with this device is difficult to use and time consuming.

Electrocardiogram (ECG) a 2-dimensional electrical tracing of the hearts activity is another tool used to help adjust the settings of pacemakers, to make the heart pump more efficiently. Furthermore, recent research has shown that this is better than echocardiogram at optimising pacemaker device settings.

A new type of ECG called cardiogoniometry (CGM) has recently been developed which creates a 3-dimensional view of the hearts electrical activity and has already been shown to be better than normal ECG at diagnosing certain conditions like angina and heart attacks. However it has never been used to try optimise the settings of the pacemakers used in CRT and may be quicker and easier to use than then other methods available. More importantly it is hoped by doing this it will reduce the symptoms that patients suffer as it is making the heart pump more efficiently.

As it has been untested and never used in this setting before, and there it is necessary to find out if the CGM machine will recognise when the settings on the pacemaker are changed.

The aims of this study is to see if the CGM machine can pick up changes to pacemaker settings, with the hope of running a later study to see if it can be used to optimise settings on the pacemaker used in CRT.
