The electrocardiograph was the first cardiological investigation introduced into Wellington Hospital, and it remains the most commonly performed.
Around 30 years after the hospital acquired its first ECG machine, the ECG as a continuous monitoring tool was introduced into hospital practice in the cardiac catheterisation laboratory and in operating theatres.    Subsequently the monitored ECG became widely used in the special units - CCU, ICU and NNU - and in the A&E, exercise laboratory, and in many other hospital environments.
