atrial
Significado: Relating to the atria — the two upper chambers of the heart that receive blood from the veins before passing it to the ventricles below.
The adjective appears most commonly in 'atrial fibrillation' (AF), the most prevalent sustained cardiac arrhythmia, affecting roughly 1.5 million people in the UK. Other uses include 'atrial flutter,' 'atrial septal defect,' and 'atrial natriuretic peptide.' In anatomy, atrium can also refer to any chamber-like space, though the cardiac sense dominates in medical usage. Understanding the atrial/ventricular distinction is fundamental to cardiology.
Ejemplos
- Atrial fibrillation significantly increases the risk of stroke if left untreated. 心房颤动如果不治疗,会显著增加中风的风险。La fibrilación auricular aumenta considerablemente el riesgo de ictus si no se trata.心房細動は治療しなければ脳卒中のリスクを著しく高める。심방세동은 치료하지 않으면 뇌졸중 위험을 현저히 높인다.
- The echocardiogram showed an atrial septal defect — a small hole between the two upper chambers of the heart. 超声心动图显示了一个房间隔缺损——心脏上方两个腔室之间的一个小孔。El ecocardiograma mostró una comunicación interauricular, un pequeño orificio entre las dos cavidades superiores del corazón.心エコー検査で心房中隔欠損——心臓上部の二つの腔室の間にある小さな穴——が確認された。심장 초음파 검사에서 심방중격결손, 즉 심장 상부 두 방 사이의 작은 구멍이 확인되었다.
- The consultant explained that atrial flutter is closely related to fibrillation but involves a more regular electrical pattern. 顾问医生解释说,心房扑动与心房颤动密切相关,但涉及更规则的电信号模式。El consultor explicó que el aleteo auricular está estrechamente relacionado con la fibrilación, pero implica un patrón eléctrico más regular.担当医は、心房粗動は心房細動と密接に関連しているが、より規則的な電気パターンを伴うと説明した。담당 전문의는 심방조동이 심방세동과 밀접한 관련이 있지만 보다 규칙적인 전기 패턴을 수반한다고 설명했다.
