An Overview of QT Dispersion Finding in Cardiac Patients,Review Article

چکیده
Background: QT duration represents the time of whole summated electric cardiac ventricular activity involving stepwise depolarization followed by repolarization. There has been a long history using surface electrocardiogram (ECG) to identify repolarization problems. The 1960s were turning point for precise mathematical methodologies. It customary in clinical practice use only interval and polarity shape T wave when evaluating an (ECG). This terminology, such as non-specific ST segment variations are widely used. An earlier theory on interlead disparities QTI length was resurrected 1990 report group led Professor John Campbell. dispersion range durations proposed measure recovery spatial dispersion. Objective: Determine relevance QTd prediction myocardial its severity. Conclusion: For patients, is easy-to-use, rapid, affordable, helpful tool helping with study interpretation, management, therapeutic orientation.

The impact of chronic hemodialysis on QT dispersion corrected QTdispersion and maximum QT-dispersion
Introduction: Sudden cardiac death is common in patients on hemodialysis and may occur in the immediate postdialysis period when ventricular premature complexes are common. QT dispersion reflecting hetovogelity in ventricle repolarization has been used for predicting patients with risk of malignant arrhythmia and sudden death. The purpose of the study was to assess the effect of hemodialysis on...
متن کاملQT dispersion: time for an obituary?
Perhaps the believers and disbelievers represent two different poles of scientific and research attitude. Some believe that the original concept of QT dispersion is correct merely because the technology can be applied to existing ECGs, and that the results more or less frequently (irrespective of the reproducibility) statistically distinguish between clinically defined groups. Others point to t...

Food fish farming is regarded as one of the most important sectors of the aquaculture industry. Salmon farming is a major contributor to the growth of the aquaculture sector. Climate change is predicted to have a complex impact on aquatic ecosystems, including fisheries and aquaculture. Climate change can cause a fluctuation in water temperature of rivers, lakes, seas, and oceans. This can chan...
