In total, 61 861 (2.30%) unique individuals were diagnosed with syncope. Results Among the study population of 2 694 442 participants, 1 381 453 (51.3%) were male, and the median (interquartile range) age was 32 (22-43) years. Sensitivity analysis excluding families with definite nonreflex syncope diagnosis was performed. Main Outcomes and Measures Odds ratios for syncope were calculated for relatives (twins, siblings, half-siblings, and cousins) of individuals who had syncope compared with relatives of individuals without syncope for reference. Data analysis was performed from June to October 2020.Įxposures Register-based syncope diagnosis among relatives: pairs of twins, siblings, half-siblings, and cousins. Linkage was also made to half-siblings and cousins. Sibling pairs born to Swedish parents between 19 were included. Objectives To determine the familial risk of syncope in first-, second-, and third-degree relatives of affected individuals and to explore the role of genes and family environment in reflex syncope.ĭesign, Setting, and Participants In this national population-based family cohort study, the Swedish multigeneration register was linked to 3 Swedish nationwide registers: hospital discharge, outpatient care, and primary care registers for the period from 1997 to 2015. Better understanding of reflex syncope predisposition may offer new therapeutic solutions. Importance Reflex syncope is the major cause of transient loss of consciousness, which affects one-third of the population, but effective treatment for individuals with severe syncope is lacking.

Sudden fall of the blood pressure of at least 20/10 mm hg when a person stands up.

Fall in blood pressure associated with dizziness, syncope and blurred vision occurring upon standing or when standing motionless in a fixed position.Symptoms generally include dizziness, blurred vision, and syncope. Orthostatic hypotension is a finding, and defined as a 20-mm hg decrease in systolic pressure or a 10-mm hg decrease in diastolic pressure 3 minutes after the person has risen from supine to standing. A significant drop in blood pressure after assuming a standing position.Syncope (fainting) due to orthostatic hypotension.Orthostatic hypotension (low blood pressure upright).nonspecific low blood pressure reading NOS ( R03.1).maternal hypotension syndrome ( O26.5-).
