The time of the day-specific distributions of the PM2.5 and QTI, as an example of ventricular repolarization measures, are presented in Figures 1 and 2, respectively.
E/e′ may be more representative of ventricular elastance than ventricular volumes per se.
When three such contractions occur in succession, as in his case, doctors speak of ventricular tachycardia.
Indications include all types of ventricular failure, for example, intraoperative or perioperative low CO syndrome, severe acute myocardial infarction, and cardiac resuscitation.
For example, DHA and EPA can ultimately increase arrhythmic thresholds, increase the threshold of ventricular fibrillation, increase heart rate variability, reduce ischemic damage, and favorably affect autonomic tone [ 30- 32].
For example, the CAST trial [29, 30] enrolled patients at risk of ventricular arrhythmias and randomized to the anti-arrhythmics moricizine, encainide or flecainide versus placebo.
MVPA has been successfully applied in many different medicine fields, for example, in gene selection for large cluster analyses [29] or in detection of ventricular fibrillation [30].
However it potentially provides important clinical insights, for example leading to a better understanding of the pathophysiology and the follow up of ventricular remodelling after therapy.
For example, assessing the haemodynamic outcome after surgery requires a reproducible and accurate assessment of ventricular function as clinical decisions are usually based on a change in serial measurements rather than a single absolute value [10].
Examples include follow-up for traumatic or non-traumatic haemorrhage, raptured aneurysms, stroke or evaluation of ventricular size in cases of hydrocephalus [6, 43, 44].
