P-wave morphologyTime domain analysisAtrial fibrillation is the most common arrhythmia with an increasing prevalence related to ageing. Its societal impact is large because of the morbidity, predominantly related to stroke as a consequence of embolization from the thrombi in the atrium, but also to...

ECG Features of Atrial FibrillationIrregularly irregular rhythm No P waves Absence of an isoelectric baseline Variable ventricular rate QRS complexes usually < 120ms, unless pre-existing bundle branch block, accessory pathway, or rate-related aberrant conduction Fibrillatory waves may be present and can...
Atrial fibrillation is a supraventricular tachyarrhythmia and the most common kind. It is caused by rapid, uncontrolled atrial contractions and uncoordinated ventricular responses.
Characteristic findings in the ECG (absence of the P-wave, irregular atrial oscillations replacing the P-waves, and the irregular ventricular response) permit a reliable diagnosis of atrial fibrillation it, most cases. The morphology of f-waves (fine or coarse) seems to be of little clinical re...
ECG localization of the site of origin of retrograde atrial activation. P wave morphology during atrial pacing along the atrioventricular (AV) ring was evaluated to develop electrocardiographic (ECG) criteria for identifying th... DM Fitzgerald,HR Hawthorne,GH Crossley,... - 《Journal of ...
Atrial Fibrillation ECG Wave Strip Pattern AFib shows irregular P wave patterns (the small “spike” just before the QRS or big spike pattern), which indicates irregular atrial contractions interrupted by QRS patterns (heartbeats or effective ventricular cardiac blood pumping). ECG Wave Pattern Strip...
The electrocardiogram (ECG) provides a wealth of information, which is of value in predicting incident AF. The PR interval and P wave...关键词: ECG-derived predictor New atrial fibrillation P-wave indices atrial remodeling DOI: 10.4022/jafib.1724 被引量: 3 ...
摘要: Objective: The aim of this study was to compare the relationship between a novel electrocardiographic (ECG) parameter P wave peak time (PWPT) and classic P wave parameters with atrial fibrillation (AF). 关键词: Electrocardiogram P wave Atrial fibrillation 年份: 2019 收藏...
