We analyze the occurrence of infarctions in relation to geomagneticactivity through the Ap index considering low and high activity levels. The distribution of the infarctions in geomagneticallycalm (Ap<10 g) and geomagnetically perturbed (Ap >50 g) periods is different. Performing a superposed epoch analysis, wenotice a prominent maximum in the distribution of infarctions one day after the Ap maximum. We conclude that the acutemyocardial infarctions morbidity seems to be responding to a threshold level of Ap between 20 - 50 g. 2004 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56843214 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.2 Vol.43 |
