My doctor told me I have multifocal VT but not to worry

In the setting of a healthy structured heart, what would cause a run of multifocal VT? I was told today by my doctor that it is nothing to worry about, but I would like to research the things that can cause it so I can ask for those to be ruled out. Thank you

Multifocal premature ventricular contractions occur when more than one site in the ventricles is the source of the electrical impulse: each peak on the ECG will have a different shape.

In the face of an otherwise normal heart, my concern would be whether you are at risk for long QT syndrome (LQTS) or Torsade de points.

This is a potential dangerous arrhythmia and I have written about this before:

In your case, how much of an evaluation have you had? If this is based on one EKG by your Family Doctor, I recommend consultation with a cardiologist, careful evaluation of your EKG, blood tests for low potassium, magnesium and calcium levels and exercise testing.

Hope this helps, come back if you have more questions,
Dr T
