The four/five-point restraint uses a lift-latch or a rotary buckle connector (Figure 5) for attachment of the pelvic harnesses. The four/five-point restraint does not have an enabling switch. Systems without an enabling switch are active (or enabled) when the system is completely electrically connected.
As genetic testing becomes increasingly available for these conditions, the Johns Hopkins Center for Inherited Heart Diseases can provide you with appropriate counseling on the risks and benefits of these tests.
In the future, genetic testing to determine personal risk estimates for heart disease may also prove useful, but this approach has not yet been scientifically validated. The chance of developing heart disease can be reduced by taking steps to prevent and control factors that put people at greater risk.uch histories can capture the effects and interactions of shared genetic, behavioral, and environmental factors that lead to disease in a family. Several genetic disorders are associated with increased risk of premature heart attacks.
