| Summary: | To assess high-definition ECG potential in evaluating the effectiveness of surgery in Wolff-Parkinson-White syndrome and paroxysmal atrio-ventricular nodal reentrant tachycardia (PAVNRT), as well as to study quality of life (QoL) in these patients, 149 individuals were examined. In total, 61 participants did not have any cardiovascular disease, 45 patients suffered from WPW syndrome, and 43 - from PAVNRT. ECG was recorded in three orthogonal Frank leads. Spectral analysis included fast Fourier transformation and multiple narrow filter usage. All extrema received were divided by frequency (low, middle, high) and amplitude (low, high). Extrema ≤40 microvolt were classified as low-amplitude (LA), >40 microvolt - as high-amplitude (HA). Extrema <40 Hz were classified as low-frequency (LF), 40-90 Hz - as middle-frequency (MF), and 90-150 Hz - as high frequency (HF). QoL was assessed by 36-Item Short-Form Health Survey (SF-36) questionnaire. Spectral-temporal mapping could be used for clarifying diagnosis in patients with supraventricular tachycardias. |
