Clozaril and Pulseless electrical activity - a phase IV clinical study of FDA data

Summary:

Pulseless electrical activity is reported as a side effect among people who take Clozaril (clozapine), especially for people who are male, 50-59 old, have been taking the drug for 10+ years also take Divalproex, and have Dyslipidaemia.
