ECG

What is an ECG?

An ECG is an interpretation of the electrical activity of the heart, and is detected by electrodes attached to the skin. It translates electrical activity into a waveform which can then be interpreted by your cardiologist. It can measure the regularity or irregularity of the heart rhythm, give information on the size of trhe cardiac chmabers, and also indicate damage to the heart muscle, and also show the effect of medication on the heart rhythm

The placement of the ECG electrodes takes around 5 minutes and an interpretation of the result is available almost immediately.
