Two out of four patients who had severe ischaemic E.C.G. changes when first accepted on to the dialysis programme showed much improvement after six months. From an analysis of 40 electrocardiograms (20 before and 20 after dialysis) of a further 17 patients it was found that the height of the T wave is a good index of the plasma potassium level. The tolerance of higher plasma potassium levels by these patients compared with patients with acute renal failure may be explained by the fact that the former do not have a hypercatabolic process and have a lesser degree of acidosis.
在首次接受透析治疗时出现严重缺血性心电图改变的4名患者中，有2名在6个月后有明显改善。通过对另外17名患者的40份心电图（透析前20份，透析后20份）进行分析发现，T波高度是血浆钾水平的良好指标。与急性肾衰竭患者相比，这些患者对较高血浆钾水平的耐受性，可能是因为前者没有高分解代谢过程，且酸中毒程度较轻。
