まとめ
マラソン大会における突然心停止（SCA）はまれである。この研究では、SCAイベントは、遅いランナーだけでなく、一般的なマラソン完走者集団と同様のペースで発生することが判明した。
科学分野:
- 心臓病学;スポーツ医学;公衆衛生
背景:
- 突然心停止（SCA）は、マラソンなどの持久系イベントにおける重大なリスクである。;トレーニングはSCAのリスクを軽減するが、レース当日のランニングペースが脆弱な個人を特定する上で果たす役割は不明である。
研究 の 目的:
- マラソン中のSCAのリスクが高い個人を特定できるランニングペースがあるかどうかを調査すること。;ランニング速度と完走者パーセンタイルに関連するSCA発生を分析すること。
主な方法:
- 認定マラソンにおけるSCA症例の将来的な収集（2011年4月～2020年3月）。;最後のスプリットタイム/フィニッシュタイムに基づくランニングペースの計算。;年齢および性別で層別化されたマラソンランキングと比較した予測フィニッシュタイム。
主要な成果:
- 453万人の出走者の中から74件のSCA症例が特定された（10万人あたり1.6件）。;中央値ペースは4時間33分フィニッシュタイム（48パーセンタイル）に相当した。;SCAイベントは、主にレースの最終段階またはフィニッシュ後に発生した。
結論:
- マラソン関連のSCAイベントは、一般的な完走者集団と同様のランニング速度で発生した。;これは、コンディショニングの悪いランナーだけがSCAのリスクが高いという考えに異議を唱えるものである。

01:17Wald-Wolfowitz Runs Test II
534
The Wald-Wolfowitz runs test, commonly referred to as the runs test, is a nonparametric test used to assess the randomness of ordered data. The test evaluates the number of runs, which are consecutive sequences of similar elements within the data. If the number of runs is significantly higher or lower than expected, the data is considered non-random, indicating a detectable pattern or structure.
For binary data, runs are identified using symbols such as + and −, or equivalently, 1s and 0s. In...

The Wald-Wolfowitz test, also known as the runs test, is a nonparametric statistical test used to assess the randomness of a sequence of two different types of elements (e.g., positive/negative values, successes/failures). It examines whether the order of the elements in a sequence is random or if there is a pattern or trend present. This nonparametric test applies to any ordered data despite the population and sample data distribution, even if a higher sample size is available.

01:22Cardiac Output II: Effect of Stroke Volume on Cardiac Output
3.2K
Cardiac output (CO), the amount of blood the heart pumps per minute, is a parameter in cardiovascular physiology determined by stroke volume and heart rate. Stroke volume, the amount of blood pushed from one of the ventricles per heartbeat, is influenced by preload, afterload, and contractility.
Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...

01:19Cardiac Output I:Effect of Heart Rate on Cardiac Output
2.5K
Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart...

01:29Cardiac Cycle
12.3K
The cardiac cycle refers to the sequence of events that occur in the heart from the beginning of one heartbeat to the next. It's characterized by alternating periods of contraction (systole) and relaxation (diastole) of the heart muscles.
During the cardiac cycle, blood flow through the heart is regulated entirely by changing pressure gradients. This sequence of events begins with the heart in a state of total relaxation, known as mid-to-late diastole, during which blood passively flows from...

01:13The Cardiac Cycle
97.8K
The heart beats rhythmically in a sequence called the cardiac cycle—a rapid coordination of contraction (systole) and relaxation (diastole).
The Process
Electrical signals—sent from the sinoatrial (SA) node in the right atrial wall to the atrioventricular (AV) node between the right atrium and right ventricle—cause both atria to simultaneously contract. When the signal reaches the AV node, it pauses for approximately a tenth of a second, allowing the atria to contract and...
