Ventricular extrasystoles P waveP wave detectionPathological ECG signalThis work introduces a new method for P wave detection in ECG signals during ventricular extrasystoles. The authors of previous works which deal with detection of P waves tested their algorithms......
This book elucidates a number of new concepts on P-wave evaluation and QRS depolarization properties, and reports on several repolarization findings never covered in previous ECG books. The content is primarily based on case reports, som... A Capucci 被引量: 0发表: 2019年 The Difficult Extra ...
Since postextrasystolic repolarization changes of VPBs were first reported by P.D.White in 1915 [10], a lot of studies have been attempted to reveal its clinical value [[11], [12], [13], [14]]. At present, it is believed that changes in the U wave after VPBs are associated with...
Serial echocardiographic and electrocardiographic (ECG) evaluations ofTPP1gene therapy-treated CLN2-affected dogs were performed starting at 8.5 months of age and continued until the time of death. Healthy related Dachshunds heterozygous for theTPP1mutation were used as age-matched controls for each t...
(but totally dissimilar in another). The ECG features favoring ventricular extrasystoles over aberrantlyconducted atrial extrasystoles include (1) wide QRS morphology, (2) a full compensatory pause, (3) presence of fusion beats, and (4) absence of a discernible premature P wave. In ...
HHMD inflates and deflates the cuff slowly (6 mmHg/s) and records also ECG and photoplethysmographic signal (PPG) at both index fingertips. Among other parameters the pulse wave transit time, PWTT is calculated. Occlusion with the cuff causes a temporary alteration in the dynamic parameters ...
ambulatory ECGBackground: Changes in U-wave amplitude after premature ventricular contractions (PVC) are known as prognostic markers in the long QT syndrome dependent on bradycardia. The purpose of the study was to find correlation between postextrasystolic ST-U segment changes and a history of ...
The present invention relates to a method for predicting cardiac risk and / or recurrence comprising, after the steps of selecting at least one wave of an electrocardiogram (ECG), segmentation of said wave, parameterization of said selected wave of an electrocardiogram in several parameters, ...
We postulated that measuring the extra-isthmus activation time (EIAT) on the counterclockwise (CCW) ECG flutter (F) wave is correlated with the extra-isthmus conduction time after proven BIB. Methods Files of 76 consecutive patients (pts; 71卤12 y) ablated for CCW AFl were reviewed. Ten ...
The release of shock wawes (1,000 to 2,000 for each treatment) is triggered by the R-wave of the patient's ECG. Arrhythmias and extrasystoles (ES) may occur. In the investigational trial, the preferred anaesthesia was continuous lumbar EA with a large volume of 2 % lidocaine extended ...
