Prognostic value of N-terminal pro-brain natriuretic peptide in patients with chronic stable angina.

abstract：:Heart potentials were recorded from the entire chest surface in 42 patients suffering from Wolff-Parkinson-White syndrome. We were able to identify six types of surface maps, according to the location of the potential maximum and minimum during the delta wave. For each of these types we suggested the most likely locat...
