[ECG changes in psychiatric patients under long-term therapy with psychopharmacological drugs (author's transl)]

1726 psychiatric patients, aged 40-69, under permanent hospitalization were examined electrocardiographically. There were few pronounced indications of a relationship between pathological ECG findings and drugs. ECG changes, mainly T-flattening, were rarest among patients treated exclusively with non-tricyclic drugs, and most often among those patients who received tricyclic and non-tricyclic compounds simultaneously. These disturbances appeared more often among women.
