Level of Magnesium in patients with Arrhythmias.
Pak J Med Health Sci Jan ;12(1):365-7.

Background: In literature many practical methods leading fewer complications were used to treat post surgical arrhythmias. There exist a controversy for magnesium (Mg) sulfate effectiveness in protecting postop arrhythmias. Many studies highlight its effective role and others are with unsolved questions. Aim: To assess the Mg levels among patients with arrhythmias and its effective role. Methods: The study design opted for the present research was observational cross section, where the cardiac patients were assessed for the levels of Magnesium in their blood serum at three points. The study duration was of six months from January to June 2017. The venue of the study was Faisalabad institute of cardiology, Faisalabad. The exclusion criteria include all patients with renal failure, past surgical history and valvular heart disease whereas all the patients of both genders above 18 years of age with normal sinus rhythms of coronary artery bypass grafting (CABG) were included in this study. Results: A total of 80 patients were recruited for this study. The mean age of the patients was 54 +/-8.9 with range 18-60. 25(31.3%) of the patient were in The age category of 36 to 45. Whereas 15(18.7%) belong to 18-35 and 40(50%) were above and equal 45 years of age. 52(65%) of the patients were male and 28(35%) were females. One patient reported complication because of high serum Mg level, and with Long CPB duration. But the level dropped to 3.5 and 5.3mg/dl on second point (ICU admission) and 3rd point (1st day postoperative) respectively. Conclusion: We may conclude a relation between serum Mg levels and the postoperative arrhythmias. The dose of supplemental Mg sulfate shows a defending role in arrhythmias occurrences.
