Electrocardiogram in different types of dizziness

We have studied the influence of neurological loadings on heart rate (HR) in patients with dizziness and correlations between types of dizziness and changes in the electrocardiography (ECG) parameters. Two hundred and twenty-one patients aged 44.82 ± 14.15 years were examined. ECG and HR have been recorded before and after neurological loadings: calculation, Takahashi, tracking, lowering the bed and diadochokinesis. All the tests resulted in HR changes. The data obtained have been discussed from the point of view of somatomorphic disorders, cardiac neurosis (F45.3 according to ICD-10) and the possibility of their detection in patients with cardiac complaints in whom ECG studies did not reveal any abnormalities. Correlations between certain types of dizziness and ECG interval indicators are discussed.
