Automated ECG diagnostic P-wave analysis using wavelets
P-wave characteristics in the human ECG are an important source of information in the diagnosis of atrial conduction pathology. However, diagnosis by visual inspection is a difficult task since the P-wave is relatively small and noise masking is often present. This paper introduces novel wavelet characteristics derived from the continuous wavelet transform (CWT) which are shown to be potentiall...
متن کاملThe prognostic importance of isolated P-Wave abnormalities.
BACKGROUND While certain P-Wave morphologies have been associated with abnormal atrial size and either pulmonary or cardiovascular (CV) disease, their relationship to mortality and specific cause of death has not been reported. METHODS Analyses were performed on the first digitally recorded electrocardiogram (ECG) on 43 903 patients at the Palo Alto Veterans Administration Medical Center sinc...

a survey was carried out in the summer of 1972 in east azerbaijan, northwest iran, to determine the prevalence of cardiovascular disease. ecg tracings were prepared from 198 women and 178 men aged 40-60. only 45% of the tracings were completely normal. q/qs abnormalities were found in 4.7% of tracings, left axis deviation in 4% tall r wave in 37%, st depression in 3.9% of men and 14.1% of women...
متن کاملECG Case of the Month: Chest Pain and ECG Abnormalities.
A 27-year-old man was admitted to the coronary care unit because of chest pain and an electrocardiogram (ECG) read by the computer as an inferior infarct and left ventricular hypertrophy (Figure).
متن کاملAcute “Pseudoischemic” ECG Abnormalities after Right Pneumonectomy
New onset of electrocardiographic (ECG) abnormalities can occur after lung surgery due to the changes in the position of structures and organs in the chest cavity. The most common heart rhythm disorder is atrial fibrillation. So-called "pseudoischemic" ECG changes that mimic classic ECG signs of acute myocardial ischemia are also often noticed. We report the case of a 68-year-old male, with no ...
