In this video, Dr. Viveka Kumar, Senior Director - Cath Lab, Max Super Speciality Hospital, Saket, will discuss the role of IV magnesium in acute MI. IV magnesium is given only for patients who have refractive arrhythmias. They get ventricular tachycardia and ventricular fibrillation even if the magnesium levels are normal. He will further talk on the data which suggests IV magnesium of 2 grams in 24 hours can save the patient. Only in arrhythmic complications, the role of magnesium is present otherwise there is no advantage in the regular use for these patients.
