چکیده
Methods We studied 90 consecutive patients without myocardial infarctions (mean age 53 years, 50% female) referred for CMR with T1 mapping that had a 12 lead EKG within 90 days. Numerous EKG parameters were evaluated visually and electronically (heart rate, PR duration, QRS amplitude and duration, QRS morphology, QRS-T angle, QRS fragmentation, T wave amplitude, QTc duration, corrected QT peak duration, T peak T end) to determine their association with myocardial fibrosis as measured by ECV.

Quantification of myocardial extracellular volume fraction in systemic AL amyloidosis: an equilibrium contrast cardiovascular magnetic resonance study.
BACKGROUND Cardiac involvement predicts outcome in systemic AL amyloidosis and influences therapeutic options. Current methods of cardiac assessment do not quantify myocardial amyloid burden. We used equilibrium contrast cardiovascular magnetic resonance (EQ-CMR) to quantify the cardiac interstitial compartment, measured as myocardial extracellular volume (ECV) fraction, hypothesizing it would ...

متن کاملCorrelation between QRS Complex Changes and Cardiac Iron Overload in Beta Thalassemia Major Patients Using T2*MRI
Background and purpose: Cardiac magnetic resonance imaging (MRI) is a costly method to assess cardiac iron overload. The presence of fragmented QRS (fQRS) indicates changes due to iron overload in cardiac tissue. The aim of this study was to evaluate the correlation between fQRS and cardiac iron overload using cardiac MRI in patients with β-thalassemia major (β-TM). Materials and methods: This...

متن کاملElectrocardiographic Predictors of Cardiovascular Outcome in Women
OBJECTIVES We sought to analyze the value of infrequently measured parameters of the 12-lead electrocardiogram (ECG) in predicting cardiovascular events in women with suspected myocardial ischemia who were referred for cardiac catheterization. BACKGROUND Routinely analyzed ECG parameters have low predictive value for cardiovascular events in women with preserved left ventricular function and su...
