Why is an electrical shock delivered to correct abnormal heart rhythm?

Why is an electrical shock delivered to correct abnormal heart rhythm?

What are the chances i get qt prolongation or abnormal heart rhythm from taking Zofran (ondansetron) 4mg tabs for nausea?

This would be unlikely at this dosing but should be watched for particularly if low potassium or calcium, or familial qtprolongation (such as in familial sudden cardiac death).

Regarding your irregular heart beat: the most important factor in determining if it's dangerous to you or not is whether or not your heart is normal. So your question is right at the "heart" of the matter! you need an evaluation with history, exam, ekg, echo, blood work, and possibly a stress test. ...Read more
