長期心電圖記錄中 RR 間期和 QT 間期的動態交互關聯分析
本研究使用時間滯後互相關分析法，發現 QT 間期與先前 RR 間期的相關性高於後續 RR 間期，且此關聯性會隨著年齡增長而減弱，並受到心率的影響。
장기 심전도 기록에서 RR 간격과 QT 간격 간의 동적 교차 상관관계 분석
본 연구는 장기 심전도 기록에서 RR 간격과 QT 간격 간의 동적 교차 상관관계를 분석하여, QT 간격이 이전 및 이후 RR 간격과 어떻게 상관관계를 갖는지, 그리고 이러한 관계가 성별, 연령 및 심박수에 따라 어떻게 달라지는지 탐구합니다.
長期心電図記録におけるRR間隔とQT間隔の動的な相互相関
本稿では、長期心電図記録を用いて、健常者におけるRR間隔とQT間隔の動的な相互相関を時間遅延相互相関分析により調査し、過去のRR間隔が現在のQT間隔に強く影響することを示唆した。
Cross-Correlation Analysis Reveals Age and Heart Rate Dependence of RR and QT Interval Dynamics in Healthy Subjects
Time-lagged cross-correlation analysis of long-term ECG recordings reveals that while RR-QT interval correlation is strongest with maximum overlap, past RR intervals have a greater influence on current QT intervals, an effect that diminishes with age and higher heart rate.
Cardiac Rupture: A Deadly Complication of Myocardial Infarction Caused by Cells Bordering Damaged Heart Tissue
Cardiac rupture, a devastating complication of myocardial infarction, is caused by a sequence of mechanical and cellular events involving cells bordering the damaged heart tissue.
New Study Finds Erythritol, a Common Sugar Substitute, May Increase Risk of Blood Clots and Heart Disease
Consuming erythritol, a widely used sugar substitute, may increase the risk of blood clots and cardiovascular events by enhancing platelet activation and aggregation.
Cardiac Amyloidosis: A Potentially Underdiagnosed Cause of Heart Failure
Cardiac amyloidosis, though considered rare, may be more prevalent than commonly thought and should be considered in the differential diagnosis for patients presenting with heart failure, especially those with unusual responses to standard treatments.
Navigating the Evolving Landscape of Durable Mechanical Circulatory Support: Insights on Patient Selection, Outcomes, and Future Advancements
The field of durable mechanical circulatory support (MCS) is navigating a complex landscape, balancing the benefits and challenges of device advancements, patient selection, and the impact of policy changes on access to heart transplantation.
Colchicine's Potential in Reducing Cardiovascular Risks: Emerging Evidence and Clinical Implications
Colchicine, an anti-inflammatory drug, has shown promise in reducing the risk of major adverse cardiovascular events (MACE) in patients with established atherosclerotic disease or multiple cardiovascular risk factors.
