Abstract:
:Forty-three patients with their first acute inferior wall myocardial infarction (IWMI) were divided into three groups according to the R/Q ratio in standard lead II. This was done to correlate these groups with the characteristic course of electrocardiographic stages. The R/Q ratio was measured on the ninth day of follow-up study, and the electrocardiographic stages were followed from the onset of the IWMI up until the ninth day. Patients with R/Q greater than 2 (group I) had a more rapid progression through the electrocardiographic stages, along with a better clinical course than patients with a lower R/Q ratio. Patients in group III, with R/Q less than 1, had a slower electrocardiographic stage progression, which correlates well with a more complicated clinical course. Group II was an intermediate group in both the electrocardiographic and clinical course. Rapid stage evolution in the first 12 hours of the IWMI was followed by a more rapid progression through stages during the rest of the follow-up period. It is suggested that the R/Q ratio in lead II can be used as a marker of the severity of IWMI, since it correlates well with the course of electrocardiographic stages. The greater the R/Q ratio, the more rapid the progression of electrocardiographic stages, and the better the clinical course. This may be an additional simple and inexpensive electrocardiographic tool for following the natural course of IWMI.
