This question provides an answer explanation that states this:
"Class IA IC III anti arrhythmic drugs prolong repolarization, as evidenced by prolongation of the QRS duration and QT interval on cardiac tracings."
Is this an accurate statement for class IC or is this an error?
I believe IC is only going to slow down phase 0 depolarization and would not change APD therefore would not prolong QRS or QT...
Can anyone back me up on this?
