[ECG in patients with hemorrhagic fever].
We analyzed 128 electrocardiograms (ECG) of 43 patients with haemorrhagic fever associated with kidney syndrome (HFKS) during an epidemic in 1989, region around Sarajevo. The greatest number of alternations was noticed in toxic phase, and the smallest number in invasive phase of disease. All alternations were transient. Extended QT interval was dominant, and was found in 19 patients (45%). Tall and peaked T wave in the case of 17 patients or in 40%, during toxic and recovering phase, was the second by its frequency. As the third by its frequency, there was U wave manifestation. We found this kind of alternation in the case of 13 patients or in 31%. Incomplete right bundle branch block was the most frequent find during invasive phase of HTKS and it was found in 3/7 of all patients. The same thing was found in 6 patients more, during toxic phase, so in total it was 21%. First degree AV block was presented in 8 patients or 19%. Other finds, ischemia, P-pulmo, arrhythmia etc. had frequency less than 10%.
