Disturbances in cardiac electrical Systole and its relationship with sudden death

Abstract

The upper limits of these measures should not exceed 10% or more. If so, it would be pathological. However, there are tables for us that are much more useful (Figure 3). These table types are very useful when we trying to find out if a QT-interval is normal, short or long (prolonged) in relation to the heart rate (Table 3).
