How to Pronounce Second-Degree Heart Block

Say it like this: SEK-und deh-GREE HART BLOK. The stress falls on the first syllable of 'second' (SEK), so you say it a bit louder and longer than the other parts. Think of it as three separate words: 'SECond' (the number), 'deFREE' (like the temperature measurement), and then 'heart block' as you normally would.

Many people accidentally stress the wrong syllable and say 'se-KUND' instead of 'SEK-und.' Others rush through 'degree' and say 'duh-GREE' instead of 'deh-GREE.' Slow down and remember: the emphasis goes on the very first syllable—SEK.

Here's how it divides: SEC-ond de-GREE HART BLOK. That's four separate words with their own syllables: 'second' has 2 syllables, 'degree' has 2 syllables, 'heart' is 1 syllable, and 'block' is 1 syllable. Breaking it into chunks makes it easier to say out loud.

'Second' refers to the second type or level of something. 'Degree' describes how severe or extensive it is (think of degrees of heat or severity). 'Heart block' means the electrical signals in your heart are being blocked or slowed down. Together, 'second-degree' tells you it's a middle-level severity, not the mildest and not the most severe.

Yes, doctors often write it as '2° AV block' or just '2° block' in medical notes. The small circle symbol means 'degree,' and 'AV' stands for 'atrioventricular' (the technical name for this type of block). You'd say this abbreviation aloud as 'second-degree AV block.'

It means that some—but not all—of the electrical messages that tell your heart to beat are getting through. Imagine a traffic light that stops some cars but lets others pass; some heartbeats happen normally, but some are skipped or delayed. It's called 'second-degree' because it's a moderate type of electrical slowdown.

These terms describe three different levels of how much the heart's electrical signals are blocked. 'First-degree' is the mildest (signals slow down but all get through), 'second-degree' is moderate (some signals don't make it through), and 'third-degree' is the most severe (no signals get through at all). The 'degree' number tells you the severity level.

A doctor might explain it to a patient like this: 'Your heart condition is called a second-degree heart block, which means that not all of your heart's electrical signals are reaching where they need to go.' Or: 'We diagnosed her with second-degree heart block during her checkup.'
