'''Electrocardiographic findings of [[procainamide]] effects''' include:

# Unlike [[Quinidine]] it is not anticholinergic
# EKG changes are less pronounced than those accompanying [[quinidine]]
# The [[QRS interval]] is increased in proportion to the plasma level
# The [[QTc interval]] is prolonged but to a lesser degree than [[quinidine]]
# [[U wave]]s become more prominent
# In high or toxic doses, it may cause high-degree block and marked widening of the QRS duration, [[PVC]]s, [[VT]], [[Torsades de pointes]], [[VF]] or [[asystole]]. These effects are seen more frequently with the IV preparation than the oral preparation
