T-wave changes in spontaneous intermittent and alternating LAH have been described. Attention has been called to the fact that, with the onset of LAH conduction, the T-wave axis shifts oppositely to that of the QRS, thus widening the QRS-T angle in the frontal plane by about 95 degrees. This has the effect of causing T-waves to become upright in leads II, III and AVF, even in those in whom T-waves were previously inverted. This described dicordance of QRS and T-wave axes is considered as evidence that LAH conduction is in fact a true conduction abnormality. As a corollary, an inverted T-wave in leads II, III or AVF in the presence of LAH is a primary abnormality and may be an indication of inferior wall myocardial ischemia or infarction. T-waves are lowered but not inverted in lead I as a result of LAH conduction and precordial leads are variably but not significantly altered.

Fifty six persons (15 men and 41 women) aged between 90 and 99 years were examined to assess their health determining longevity. Circulatory system was evaluated with the aid of anamnesis, physical examination, chest X-ray and ECG. Clinical symptoms of the circulatory disease were diagnosed in 55.4% of tested persons, including: ischaemic heart disease in 42.9%, arterial hypertension in 35.7%, and circulatory failure in 23.2%. Normal ECG records were noted in 10.7% of the tested elderly persons. The most frequent electrographic abnormalities included: decrease in ST, LAH and atrio-ventricular block of the I degree. Incidence of ECG abnormalities did not depend upon the clinical state. An advanced age (over 90 years) is achieved also by the persons with marked circulatory disorders.

Elderly diabetic patients were followed up prospectively for 4 years to see the effects of blood pressure and dyslipidemia on the development of diabetic micro- and macroangiopathies. We studied 84 elderly diabetic patients whom we divided into four groups according to the association of above complications: (1) diabetes alone group (DM), (2) hypertensive diabetic group (DM + HT), (3) hyperlipidemic diabetic group (DM + HL), and (4) hypertensive and hyperlipidemic diabetic group (DM + HTL). The treatment of diabetes was different among the groups. Glycemic control such as fasting blood glucose and HbA1c did not change between groups or through the follow-up years. As a matter of course, blood pressure of DM was lower and triglyceride of HTL was higher than in other groups. Microangiopathies such as retinopathy, nephropathy, and neuropathy and macroangiopathies such as ischemic heart disease (IHD), cerebral vascular disease (CVD), and arteriosclerosis obliterans were evaluated by using a grading scale according to the severity. The grade of microangiopathies in DM + HT increased gradually during the follow-up years and the grade of IHD and CVD in DM + HTL was relatively higher than in the other groups. Our findings support the general principle of control of hypertension and hyperlipidemia for the prevention of diabetic microangiopathy and macroangiopathy in the elderly diabetic patients.
