Title:
Detection of hypotension during hemodialysis using the ECG
Type:
conference paper
Abstract:
There is today a lack of clinical techniques for detecting
acute hypotension during conventional hemodialysis treat
-ment, despite the fact that hypotension remains the - mosr common acute complication during hemodialysis.
Hypotension is often followed by nausea, vomiting, and
even fainting, not only strenuous for the patient but
requires considerable attention from the nursing staf. The
problem of detecting hypotension was studied by means
of a multimodal database. The database consists of
30 treatments in which each treatment includes several
simultaneously acquired signals. Acute .symptomatic
hypotension occurred in 2 of the 30 treatments. An
ECG-based method for detecting hypotension has been
developed. n e method involves information on heart
rate variability (HRV) and ectopic beat patterns. The
proposed method does not only detect the two cases of acute hypotension but also provides information of the patient's propensity to hypotension at an early stage of hemodialysis.
