摘要:

Background:The signal‐averaged ECG is a widely used and accepted technique for analysis of low‐level cardiac signals. This article reviews a new and enhanced form of ECG signal averaging: the time‐frequency plane Wiener (TFPW) filter.Methods:The TFPW filter accelerates the process of noise reduction. It facilitates use of signal averaging in settings previously unexplored with the technique, where a limited number of beats may be available.Conclusion:Example applications of the TFPW filter include improved analysis of ventricular late potentials and analysis of dynamic events, such as transient isc

摘要:

ABSTRACT:The 1887 introduction of electrocardiography as a noninvasive investigative technique on man by Augustus Waller, and Wilhelm Einthoven's electrocardiograph from 1901 remain the two major landmarks in the 100‐year history of electrocardiography. The progress in our knowledge of the mechanism and interpretation of the ECG hasevolved throughout these 100 years in a succession of relatively small steps contributed by many unsung heroes, although often even relatively minor contributions by a few dominant 'stars notably Thomas Lewis and Frank Wilson, are perceived as giant leaps. The gradual evolution of our concepts of the ECG are reviewed against the historical background of the events involved from the time of Waller's discovery to the end of the second world wa
