SummaryThis narrative review summarizes current available information about cardiac arrhythmias (QT prolongation, Torsade de pointes Tachycardia [TdP], sudden cardiac death) associated with psychiatric medication. Among the most commonly used antipsychotics, amisulpride and ziprasidone are most frequently associated with TdP. Treatment with some antidepressants (SSRIs, tricyclic antidepressants) is associated with a 5- to 6-fold increase in the incidence of out-of-hospital cardiac arrest. Lithium is associated with bradycardia, T-wave changes and AV-block; anxiolytics of the benzodiazepine group do usually not have cardiac side effects. The combination of multiple drugs (including medications from general medicine) that prolong the QT interval has a particularly high cardiac risk.

Abstract:Excitable media, such as nerve, heart and the Belousov-Zhabo- tinsky reaction, exhibit a large excursion from equilibrium in response to a small but finite perturbation. Assuming a one-dimensional ring geometry of sufficient length, excitable media support a periodic wave of circulation. As in the periodic stimulation of oscillations in ordinary differential equations, the effects of periodic stimuli of the periodically circulating wave can be described by a one-dimensional Poincaré map. Depending on the period and intensity of the stimulus as well as its initial phase, either entrainment or termination of the original circulating wave is observed. These phenomena are directly related to clinical observations concerning periodic stimulation of a class of cardiac arrhythmias caused by reentrant wave propagation in the human heart.

Objective: To study the significance of serum magnesium levels during COPD exacerbation and stability.Materials & Methods: The patient population consisted of all patients of COPD admitted as acute exacerbation as defined by the Anthonisens criteria, from June 2006 to may 2008. Same patients one month post discharge presenting to the OPD for routine check up as stable COPD served as controls. Results: A total number of 77 patients of COPD presenting as acute exacerbation were included in the study. The incidence of Hypomagnesaemia was 33.8% at admission; 5% at discharge and 4% at one month of post discharge in COPD patients. The mean serum magnesium levels were significantly lower in cases than controls (1.88±0.67mg/ dl V/S 2.3±0.36mg/dl; p<0.0001). Also, hypomagnesemia was present in higher number of cases (22/77, 33.8%) compared to controls, 3/75, 4.0%; (p<0.0001). Patients of COPD with acute exacerbation and hypomagnesemia, had longer duration of symptoms and had advanced stage III of COPD (p<0.001); and had raised mean corpuscle volume (p<0.045) and longer hospital stay (p<0.008). Conclusion: We conclude COPD exacerbation is associated with hypomagnesemia. The duration of symptoms of more than 8 days, advanced stage of COPD (stage III) and raised MCV were associated with hypomagnesemia. We recommend to monitor serum magnesium levels in COPD patients with acute exacerbation at the time of admission and during their stay in the hospital.J Med Sci.2010;13(1);15-19
