What is the EKG? Explain the following waves and intervals: P-wave, P-R interval, QRS wave, S-T segment, QT interval and T wave. Briefly explain how the heart sounds are generated - that is, what activity of the heart causes the heart sounds?
In peripheral pneumatic arterial tonometry (PAT), digital pulse wave amplitude at baseline (preocclusion) and changes during reactive hyperemia are recorded and the reactive hyperemia-PAT index (RHI) is calculated as a standardized post-/preocclusion ratio [47,48]. RHI is correlated with coronary...
Wie häufig ventrikuläre Herzrhythmusstörungen beobachtet werden, wird im wesentlichen durch die Dauer und Art der EKG-Registrierung bestimmt.
