A cousin of mine has had chronic atrial fibrillation since 3 months ago. The cardiologist at a private medical centre was not able to help much to control the
rate, and he was prescribed Herbesser 200mg (diltiazem), Propranolol 20mg (10mg x 2), Lasix, Slow K (potassium supplement), warfarin 2mg and rosuvastatin 10mg (for cholesterol). But his condition persists. He gets breathless easily.
