Background Dynamic changes in the fQRS complex between the initial and follow-up ECG
in patients with acute pulmonary embolism (APE) have rarely been studied. Objective The …

Background Electrocardiographic (ECG) abnormalities in pulmonary embolism (PE) are
increasingly reported, and mounting data have recommended that ECG plays a crucial role …

Background: Acute Pulmonary embolism (APE) is considered one of the deadliest
cardiovascular diseases. Electrocardiographic (ECG) abnormalities in pulmonary embolism …

Background Presence of fragmented QRS (fQRS) complex in a 12-lead electrocardiogram
(ECG) has been shown to represent alternation of myocardial activation owing to myocardial …

Background Fragmented QRS (fQRS) on electrocardiography is potentially valuable in
prognosticating acute pulmonary embolism (PE). ECG is one of the first tests performed in …

Background This study aimed to investigate the diagnostic value of QRS and S wave
variation in patients admitted to the emergency department with suspicion of acute …

Objectives Pulmonary embolism (PE) is one of the leading causes of cardiovascular
mortality worldwide. Electrocardiography (ECG) may provide useful information for patients …

Registries and hospital discharge datasets of unselected patients with pulmonary embolism
show 30-day all-cause mortality rates of approximately 10%.[1] Clinical findings from …

Aims To test the hypothesis that Qr in V1is a predictor of pulmonary embolism, right
ventricular strain, and adverse clinical outcome. Methods and Results ECG's from 151 …

Objective: The frontal QRS-T angle (fQRS-T) is associated with myocardial ischemia and
ventricular arrhythmias. On the other hand, acute pulmonary embolism (APE) is a major risk …
