Which type of medical device is an electrocardiograph (ECG)?

• A. A therapeutic device
• B. A diagnostic device used to obtain electrical activity of the heart
• C. Monitoring equipment for vital signs
• D. A surgical instrument

Answer: (B)

An electrocardiograph (ECG) is classified as a diagnostic device primarily because its main function is to record the electrical activity of the heart. This device provides critical information about heart rhythm, heart rate, and can help identify various cardiac conditions such as arrhythmias, myocardial infarctions, and other heart diseases. By visualizing the electrical impulses generated by the heart over time, healthcare providers can diagnose conditions that require medical intervention. The focus of an ECG is not to treat conditions or serve as a surgical instrument, which distinguishes it from therapeutic devices and surgical tools. While it can aid in monitoring vital signs by keeping track of heart activity, its primary role is diagnostic, allowing for assessments that will guide further medical decisions and treatments.
