What is an electrocardiograph?

A device to monitor electrical brain activity
A device to monitor electrical heart activity
A device for measuring blood pressure
A device for observing muscle contractions

The correct answer is: A device to monitor electrical heart activity

An electrocardiograph is a device used to monitor and record the electrical activity of the heart, specifically the rhythm and strength of heartbeats. The incorrect options are - A: This option refers to an electroencephalograph (EEG), which is used to monitor electrical brain activity, not heart activity. - C: This option refers to a sphygmomanometer, which is used to measure blood pressure, not heart activity. - D: This option could refer to a variety of devices used to observe muscle contractions, such as electromyography (EMG) or electrotherapy machines, but not specifically for monitoring heart activity like an electrocardiograph does.
