metadata.value: The objective of the study was to investigate systolic duration on the basis of the QT interval in an
  ECG. We observed 246 coronary heart disease and hypertensive patients. 134 of them had a functional
  stress test for revealing latent heart failure. Systolic duration reflects ventricular contractile function.
  The difference between the values in the actual QT interval and the one corrected for the heart rate is
  indicative of myocardial contractile dysfunction and heart failure. We have found ventricular systole
  elongation in patients’ ECGs, which expressly depends on heart failure severity. Functional stress tests
  help to reveal that in the event of asymptomatic chronic heart failure. They cause the QT interval
  prolongation, and therefore, contractile dysfunction of the ventricles. So, heart failure is based on
  contractile dysfunction of the cardiac muscle. Refs 19. Tables 2.
