How to Pronounce Diastolic Dysfunction

Say it like this: dy-ah-STOL-ik dis-FUNK-shun. The stress goes on the third syllable of the first word (STOL) and the first syllable of the second word (FUNK). Think of it as "dy-uh-STAHL-ik" with a strong emphasis on the STOL part.

Diastolic comes from the Greek word 'diastole,' which means 'separation' or 'expansion.' It describes the phase when your heart relaxes and expands to fill with blood, as opposed to systole (the contraction phase).

Dysfunction is a combination of two parts: 'dys-' (meaning bad or abnormal) and 'function' (how something works). So dysfunction simply means something is not working the way it should.

Break it like this: di-a-STOL-ic dys-FUNC-tion. That's five syllables for the first word and three for the second word, making it an eight-syllable term in total.

Many people put the stress on the wrong syllable and say 'dy-ah-stol-IC' (with stress on the last syllable), but the correct way is 'dy-ah-STOL-ic' (with stress on the third syllable). Listen for that strong STOL sound in the middle.

It's a condition where the heart's relaxation phase isn't working properly, making the heart feel stiff. In plain English, it means the heart has trouble filling up with blood the way it should during the resting part of the heartbeat.

Other words using this root include 'diastole' (the relaxation phase itself) and 'diastolic pressure' (the lower number in a blood pressure reading, measured during heart relaxation). Both words focus on that filling and relaxation phase of the heartbeat.

You might hear someone say: 'The doctor explained that the imaging showed diastolic dysfunction, meaning the heart wasn't filling as efficiently as it should during the relaxation phase.' This uses the term to describe a specific heart function issue.
