What is the rhythm torsades de pointes from?

Answer 1

Torsades de Pointes is a very dangerous condition that can lead to irregular heartbeats, which can lead to lightheadedness or passing out, and even death.

It is caused by a delay in what is called the "Q-T interval". This is the time it takes the heart to beat, then recover and become ready for another beat. A prolonged QT interval may be inherited, caused by some medications, or low levels of certain electrolytes.

If you experience heart palpitations, episodes of lightheadedness, bouts of rapid heart rate, you must see your doctor for an EKG. You might have undiagnosed genetic prolongation of your QT interval, and you will need close monitoring.

If you have a chronic health condition such as liver or kidney disease, you may have rapid changes in your electrolyte levels which may lead to a prolonged QT interval. Electrolytes typically involved are Potassium and Magnesium. Of note, bouts of diarrhea will lower your Potassium levels. If you have diarrhea for longer than two days, you should consult with your doctor to check your electrolytes. Using Sports drinks while you have diarrhea may be helpful. This does not apply to individuals with a chronic illness.

If you are ever told that you have a "long QT interval", you must take this very seriously, and not miss any appointments with your doctor or a specialist for further evaluations.
