FAQ
Frequently Asked Questions
No. An electrocardiogram (ECG/EKG) records the heart's electrical activity. A sphygmogram records the mechanical pressure wave of the pulse in an artery.
No. The sphygmograph and its sphygmogram are obsolete instruments and records. Modern, more sophisticated techniques like ultrasound, pressure catheters, and photoplethysmography are used instead.
It derives from Greek roots: 'sphygmos' (pulse) and 'gramma' (something written). The initial consonant cluster 'sphygm-' is uncommon in English and the 'g' is hard, not soft.
For most learners, there is little practical value. Its utility is limited to reading very old medical texts or understanding the history of medical technology. It serves as an example of highly technical, Greco-Latin derived scientific vocabulary.

Sphygmogram is usually technical / medical in register.
Learning
Memory Aids
Mnemonic
Think: 'Sphygmo' (relating to pulse, as in sphygmomanometer) + 'gram' (something written/drawn, as in diagram). So, a 'pulse-drawing'.
Conceptual Metaphor
THE PULSE IS A WAVE (graphically represented as a line on a chart).
