Uncertainty principle of signal-averaged electrocardiography.
BACKGROUND Signal-averaged ECG (SAECG) reproducibility is reported to have a component that is independent of residual noise. Methods and Results-In group 1, multiple paired SAECGs were obtained to noise levels of 0.3+/-0.1 and 0.5+/-0.2 microV. For the 0.5- and 0. 3-microV noise recordings, QRS duration (QRSd) was 101.2+/-11.3 and 104.6+/-9.6 ms, respectively (P<0.0001), and the differences in...
متن کاملMain indications and long-term outcomes of reoperation after initial repair of tetralogy of Fallot
Background and Objective: The aim of this study was to analyze our indications, surgical procedures, and clinical outcomes of patients undergoing reoperation after surgical correction of tetralogy of Fallot (TOF). Methods: Thirty seven consecutive patients who underwent reoperation late after intra-cardiac repair of TOF within a period of 10 years were assessed. Results: The most co...
متن کاملEchocardiographic Assessment after Surgical Repair of Tetralogy of Fallot
Surgical correction of tetralogy of Fallot is still one of the most frequently performed intervention in pediatric cardiac surgery, and in many cases, it is far from being a complete and definitive correction. It is rather an excellent palliation that solves the problem of cyanosis, but predisposes the patients to medical and surgical complications during follow-up. The decision-making process ...

متن کاملsignal-averaged electrocardiography in patients with advanced heart failure: a better indicator of left ventricular enlargement compared with conventional electrocardiography
background : the signal-averaged electrocardiography is a noninvasive method to evaluate the presence of the potentials generated by tissues activated later than their usual timing in the cardiac cycle. the purpose of this study was to demonstrate the correlation between the filtered qrs duration obtained via the signal-averaged electrocardiography and left ventricular dimensions and volumes an...
