Over four decades of high frequency electrocardiography research have provided a body of
knowledge about QRS changes during myocardial ischemia, and the techniques to measure …

Chapter 1 presented a description of the ECG in terms of its etiology and clinical features,
and Chapter 2 an overview of the possible sources of error introduced in the hardware …

Abstract Electrocardiographic (ECG) Heart Age conveying cardiovascular risk has been
estimated by both Bayesian and artificial intelligence approaches. We hypothesised that …

The electrocardiogram (ECG) continues to be a critical component of the evaluation of
patients who have signs and symptoms of emergency cardiac conditions. This tool is now …

In this study, the upward (I US) and downward (I DS) slopes of the QRS complex are
proposed as indices for quantifying ischemia-induced electrocardiogram (ECG) changes …

Background Resting conventional 12-lead ECG has low sensitivity for detection of coronary
artery disease (CAD) and left ventricular hypertrophy (LVH) and low positive predictive value …

INTRODUCTION: Our primary objective was to ascertain which commonly used 12-to-Frank-
lead transformation yields spatial QRS-T angle values closest to those obtained from …

Purpose The aim of this proof-of-concept study is to introduce new high-dynamic ECG
technique with potential to detect temporal-spatial distribution of ventricular electrical …

INTRODUCTION: We compared the diagnostic utility of various planar QRS-T angles to that
of the spatial QRS-T angle in detecting various cardiac diseases. MATERIALS AND …

INTRODUCTION: Twelve-lead electrocardiogram (ECG) is used to screen for hypertrophic
cardiomyopathy (HCM), but up to 25% of HCM patients do not have distinctly abnormal …
