Abstract：ObjectiveTo study the significance of obvious U wave (The criterion: the amplitude of U wave of every lead is larger than half of the amplitude of T wave of the same lead) inspected by electrocardiogram(ECG) of patients with stroke.MethodsRetrospectively analyse 546 cases of patients definitely diagnosed with stroke and separately carry out ECG examinations and biochemical tests.ResultsThere were 22 cases who were observed obvious U waves through ECG, accounting for 4.03% of all the 546 cases. Two cases were detected obvious U waves complicated with hypokalemia, accounting for 0.366% (χ2=17, P＜0.001).ConclusionThe obvious U wave by ECG is not necessarily caused by hypokalemia. We should give compositive analysis clinically.
