On this episode Dave talks about how the QT interval is a big
deal and how we should be looking at it each time we perform an
QT Interval - The time from the beginning of the Q wave to the
end of the T wave.
Also In This Episode
- Please start looking at the QTc as part of your regular ECG
- Torsades de Pointes is a specific form of 'Polymorphic
Ventricular Tachycardia' caused by a 'Long QT'. Watch out and
- QT little 'c' which stands for (corrected). What it is
correcting for? It's correcting for 'RATE' and averaging everything
to 60 beats per minute.
- QTc > 0.50 sec = a clinically significant prolonged QT
interval and you need to tell somebody about it!!
- Patients at higher risk - Methadone and medications of the
Mycin family are notorious for prolonging the QT interval
to name just a very few. Brush up on all the other
medications that prolong the QT.
- Take a closer look at the QTc in patients who are elderly and
perhaps suffer from chronic renal insufficiency...they are higher
risk patients for a prolonged QT.
- And don't forget...If you encounter a patient in Torsades. Once
you fix the rhythm, immediately as yourself...Hmm why did this
patient have a prolonged QT interval??? So it doesn't happen
