Effect of burden and origin sites of premature ventricular contractions on left ventricular function by 7-day Holter monitor.
Recent studies have shown that premature ventricular contractions (PVCs) could enlarge the heart, but its risk factors are incompletely understood as a single 24-hour recording cannot reflect the true PVC burden due to day-to-day variability. Our purpose was to investigate the effect of burden and origin sites on left ventricular (LV) function in patients with PVCs by 7-day Holter electrocardio...
متن کاملClassification of Premature Ventricular Contraction in ECG
Cardiac arrhythmia is one of the most important indicators of heart disease. Premature ventricular contractions (PVCs) are a common form of cardiac arrhythmia caused by ectopic heartbeats. The detection of PVCs by means of ECG (electrocardiogram) signals is important for the prediction of possible heart failure. This study focuses on the classification of PVC heartbeats from ECG signals and, in...

Day - to - Day Variation of the Normal Orthogonal Electrocardiogram
Day-to-day variation of the corrected orthogonial electrocardiogram was investigated in 20 normal subjects. Ten recordings were made in each individual witlh chest electrode positions left unmarked first, after which 10 subjects underwent another series of 10 consecutive daily recordings with marked electrode locations. Mean and maximal day-to-day variations of durations and amplitudes of diffe...
متن کاملA population approach to the study of emotion: diurnal rhythms of a working day examined with the Day Reconstruction Method.
To date, diurnal rhythms of emotions have been studied with real-time data collection methods mostly in relatively small samples. The Day Reconstruction Method (DRM), a new survey instrument that reconstructs the emotions of a day, is examined as a method for enabling large-scale investigations of rhythms. Diurnal cycles were observed for 12 emotion adjectives in 909 women over a working day. B...
