Hey guys,
I'm an M2 studying cardio now, and antiarrythmic pharm is giving me a bit of a headache. I'm able to understand the effects of the drugs on the AP duration, upstroke (magnitude), QT interval, etc.
What's taking a little more effort is understanding the rationale behind which drug and class to use for specific types of arrhythmias. For example, I know that IA are used in A fib, simply by memorization. My question is WHY is it that the prolonged AP duration with the diminished upstroke are effective in treating atrial fibrillation. I guess I can say that i'm looking for a good resource to understand the Pharmo-physiology (is that even a word?)
If anyone could give me some recommendations it would be appreciated.
