Thank you very much for replying... The imformation really helps , and I appreciate it
The concurrent use of class IA or class III antiarrhythmic agents with other medications that can prolong the QT interval should preferably be avoided unless benefits are anticipated to outweigh the risks (i.e. you won't find many doctors that will prescribe 2 antiarrhythmic agents together). Caution and clinical monitoring are recommended if these agents are prescribed together, especially to patients with underlying risk factors. Generally it is commmon to see a anti-hypertensive, a antiarrhythmic, and possibly a cardiogenic agent such as digoxin, and a diuretic, prescribed together when heart disease exists. This is not unusual. Good luck with your research!
