1
It can present with symptoms such as palpitation, presyncope or syncope.
2
We confirmed much lower rates of syncope and presyncope among young black donors.
3
He received two appropriate shocks which were associated with presyncope.
4
Incidence of syncope and presyncope was compared between randomization groups using multivariable logistic regression.
5
Background: Blood centers rely heavily on adolescent donors to meet blood demand, but presyncope and syncope are more frequent in younger donors.
6
Our adolescent donors had lower overall syncope and presyncope rates than similar populations in the United States, limiting the statistical power of the study.
7
Conclusion: Preloading adolescent donors with 500 mL of water did not have a major effect in reducing syncope and presyncope in South African adolescent donors.
