The QRS complex and ST segment in the ECGs of 80 patients who died of an acute myocardial infarction (MI) were studied in relation to the extent of the MI (subendocardial vs. transmural). Changes in the QRS complex developed in nine out of the 15 cases with an acute subendocardial MI. Five of these cases fulfilled the conventional QRS criteria for a myocardial infarction. A definite ST segment depression (a J point depression of 2 mm. or more in at least one lead, and a horizontal or downward sloping ST segment with a minimum duration of 0.08 sec.) occurred most frequently in connection with a circumferential subendocardial MI (88 per cent), but it was also found in a regional subendocardial (43 per cent) and transmural MI (43 per cent). In 17 per cent of the cases with a transmural MI, this was the only ECG abnormality. It is concluded that cases with a subendocardial MI cannot always be distinguished from transmural MI on the basis of the presence or absence of the QRS changes, and that an ST segment depression, as defined in this study, can give additional information in the evaluation of an acute phase of an MI. 相似文献

A terminal r wave in Lead V1 lower than 0.6 mV. was studied in the ECGs of four groups: (1) 104 healthy children, (2) 207 healthy young adults, (3) 171 patients with no autopsy evidence of a cardiopulmonary disease, and (4) 1,078 autopsy patients with a cardiopulmonary disease. Cases with a complete right bundle branch block were excluded. A terminal r wave occurred in 2.9 per cent healthy children, 1.4 per cent of healthy young adults, 0.6 per cent of patients without and in 5.9 per cent of patients with autopsy evidence of a cardiopulmonary disease. The occurrence of a terminal r wave was most common in pulmonary patients (10 per cent). But it was also found in patients with an anterior or a posterior myocardial infarction and in some cases of left ventricular hypertrophy. In the autopsy series RVH occurred in 57 per cent of patients with a Qr pattern, in 30 per cent of patients with a terminal r wave higher than the initial one, and in none of the patients with a terminal r wave lower than the initial one. It is concluded that the height of the terminal r wave has clinical significance. A terminal r wave higher than the initial one in Lead V1 is associated with a cardiopulmonary disease in subjects over 30 years of age, while an r wave lower than the initial one seems to be an innocent finding. 相似文献

AIM: In previous experiments we have demonstrated that by administering low doses of cholecystokinin-octapeptide (CCK-8), the process of regeneration following L-arginine (Arg)-induced pancreatitis is accelerated. In rats that were also diabetic (induced by streptozotocin, STZ), pancreatic regeneration was not observed. The aim of this study was to deduce whether the administration of exogenous insulin could in fact restore the hypertrophic effect of CCK-8 in diabetic-pancreatitic rats.METHODS: Male Wistar rats were used for the experiments.Diabetes mellitus was induced by administering 60 mg/kg body mass of STZ intraperitoneally (i.p.), then, on d 8, pancreatitis was induced by 200 mg/100 g body mass Argi.p. twice at an interval of 1 h. The animals were injected subcutaneously twice daily (at 7 a.m. and 7 p.m.) with 1 μglkg of CCK-8 and/or 2 IU mixed insulin (300 g/L shortaction and 700 g/L intermediate-action insulin) for 14 d after pancreatitis induction. Following this the animals were killed and the serum amylase, glucose and insulin levels as well as the plasma glucagon levels, the pancreatic mass/body mass ratio (pm/bm), the pancreatic contents of DNA, protein, amylase, lipase and trypsinogen were measured. Pancreatic tissue samples were examined by light microscopy on paraffin-embedded sections.RESULTS: In the diabetic-pancreatitic rats treatment with insulin and CCK-8 significantly elevated pw/bm and the pancreatic contents of protein, amylase and lipase vs the rats receiving only CCK-8 treatment. CCK-8 administered in combination with insulin also elevated the number of acinar cells with mitotic activities, whereas CCK-8 alone had no effect on laboratory parameters or the mitotic activities in diabetic-pancreatitic rats.CONCLUSION: Despite the hypertrophic effect of CCK-8 being absent following acute pancreatitis in diabetic-rats,the simultaneous administration of exogenous insulin restored this effect. Our results clearly demonstrate that insulin is necessary for the hypertrophic effect of low-doses of CCK-8 following acute pancreatitis. 相似文献
