4.1% of sudden cardiac deaths in the 16-64 age-group are unexplained. In this group, cardiac pathological findings are normal and toxicological tests are negative; termed sudden arrhythmic death syndrome (SADS). We searched for evidence of inherited cardiac disease in cases of SADS. Of 147 first-degree relatives of 32 people who died of SADS, 109 (74%)(More)
We used principal component analysis (PCA) of the QRS complex to assess depolarisation heterogeity during ajmaline test in 96 patients with suspected Brugada Syndrome (BS). PCA was performed on 15-lead ECGs (12 leads +V1, V2 and V3 from 3 rd intercostal space, V1h to V3h using a) V1, V2 and V3 (QRS-PCAstand), b) V1h, V2h and V3h (QRS-PCAhigh), and c) V1 to(More)
Microvolt 2:1 T wave alternans (TWA) and increased beat-to-beat repolarization variability have been reported in Brugada syndrome (BS) and could be related to increased arrhythmic risk. We hypothesized that among patients (pts) with suspected BS, those with positive diagnostic ajmaline test (i.e. likely carriers of BS mutations) have greater TWA or(More)
The goal of this study was to compare several ECG signal decomposition methods in order to enhance the accuracy of T wave end localisation. PTB Diagnostic ECG Database comprising 549 recordings was used. The idea was to combine the 8 independent leads (I, II, V1,…, V6) of the standard 12-leads ECG into a single lead. The signal decomposition methods were(More)
