[Holter heart rhythm disorders in patients with acute kidney injury during hemodialysis].

BACKGROUND

The presence of acute renal injury has been associated with increased cardiovascular morbidity and mortality (sudden death and arrhythmias).

OBJECTIVE

To know the frequency of heart rhythm disorders documented by Holter in patients in need of intermittent hemodialysis due to acute renal injury.

MATERIAL AND

METHODS

A prospective observational study was conducted including patients with a diagnosis of acute renal injury who received intermittent hemodialysis; demographic, clinical and laboratory data were collected from 28 patients. Monitoring was carried out through Holter before, during and after the hemodialysis session. Nonparametric statistics were used, with a significant value of p < 0.05. Risks were established with logistic regression.

RESULTS

There was a significant difference in supraventricular extra systoles (82.1% vs. 57.1%), ventricular extra systoles (26.7% vs. 3.6%), and supraventricular tachycardia (6.7% vs. 3.6%). The rest of the rhythm alterations without significance.

CONCLUSIONS

Intermittent hemodialysis is a factor associated with the appearance of heart rhythm disorders. The death of patients with acute renal injury and substitution was related to ventricular extra systole detected by transhemodialysis Holter.
