The electrocardiograph is the primary device used for selecting and displaying ECG strip data because it is specifically designed for this purpose. It captures the electrical activity of the heart and presents it in a visual format, typically as a waveform, which can be printed out or displayed on a screen. This essential function allows healthcare professionals to analyze heart rhythms, identify abnormalities, and make informed decisions regarding patient care.

While the ECG monitor does display real-time heart data, its primary function is to continuously monitor and alert caregivers to any changes in the patient's cardiac condition, rather than to specifically select and display recorded ECG strips. The defibrillator is used for delivering an electric shock to restore normal rhythm in case of cardiac arrest and does not function in the detailed recording and display of ECG data. The pulse oximeter measures blood oxygen levels and heart rate but does not provide information about the electrical activity of the heart itself. Hence, the electrocardiograph is the most appropriate choice for selecting and displaying ECG strip data.
