Abstract :
The aim of this study was to analyze the ability of heart rate variability (HRV) indices to identify patients with heart diseases as a first diagnosis by the general practitioner (GP). In this study we applied linear and non-linear methods of short-term HRV analysis. 78 healthy male subjects (REF) and 378 male patients (PAT) with several heart diseases were investigated considering two age groups: younger men (YM) and elderly men (EM). The identification of patients with heart diseases was performed using a scoring system based on cut-off parameters calculated from REF. Comparing REF with PAT, in both age matched groups the specificity were selected to be 100%. Combining the best indices from all domains revealed sensitivities of 74.07% for YM and 77.44% for EM. In conclusion, short-term HRV analysis might offer a screening of heart diseases as a first diagnosis by the GP. Especially nonlinear parameters contribute to diagnosing heart diseases in men.
