まとめ
TpTe区間は,子ども,特に異常体重の子どもにおける心律乱症リスクを評価するための重要な指標です. このパラメータをQTインターバルと共に測定することで,悪性心室動脈不律症のリスク分層化を改善することができます.
科学分野:
- 心臓病学 心臓病学
- 小児科は小児科です.
- 臨床電気生理学 臨床電気生理学
背景:
- 延長されたQTとTpTeの間隔を含む電気心臓学的再極化異常は,悪性心室動脈不全のリスクを特定するために重要である.
- 体重の変動を考慮して,子供におけるこれらのパラメータの評価は,正確な診断とリスクの階層化をするために不可欠です.
研究 の 目的:
- 発心不良と発心不良の小児における心電学的再偏極化パラメータを,体重によって層分化して比較する.
- 身体質量指数 (BMI) と心律乱症の種類が異なる小児患者のTpTe,QTp,および矯正QT間隔 (QTcB,QTcF) の診断値を調べる.
主な方法:
- リポラライゼーションパラメータ (TpTe,QTp,QTcB,QTcF) は,12リードのECGのリードV5から測定されました.
- 室内および上室内動脈不律の子どもは,正常および異常な体重 (BMIとコール指数を使用して) によって分類され,正常体重の対照群と比較されました.
主要な成果:
- TpTeとQTcFの間隔は,心室不律症の肥満児では,心室不律症の子どもと比較して,有意に長かった.
- 腹腔動脈不律症の肥満児では,超腹腔動脈不律症と比較して,TpTe間隔の有意な延長が観察されました.
- 統計的に有意な差異 (p < 0.0001) がTpTe間隔で5つのグループ全体で発見され,不律症と体重状態に対する敏感性を強調した.
結論:
- TpTe間隔は,体重に関係なく,心室不律症の子どもでは,心室不律症または心室不律症の子どもと比較して,かなり長くなっています.
- QT間隔に加えて,TpTe間隔の定期的な測定は,心律不良の子供に推奨されます.
- 動脈不良や肥満の小児におけるTpTe間隔の臨床的意義を明らかにするために,さらなる大規模な研究が必要である.

ECG Interpretation of Arrhythmias I: Sinus Arrhythmias
867
Arrhythmias are disturbances in the heart's rhythm that lead to abnormal heartbeats. These irregularities can originate from different parts of the heart and are classified based on their origin and nature.
Types of Arrhythmias
Sinus Node Arrhythmias
Sinus Bradycardia: Originating from the sinoatrial (SA) node, sinus bradycardia involves slower impulses, resulting in a heart rate of less than 60 beats per minute (bpm). Causes include sleep, vagal stimulation, beta-blockers, hypothyroidism,...

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...

Weighted Mean
6.5K
While taking the arithmetic, geometric, or harmonic mean of a sample data set, equal importance is assigned to all the data points. However, all the values may not always be equally important in some data sets. An intrinsic bias might make it more important to give more weightage to specific values over others.
For example, consider the number of goals scored in the matches of a tournament. While computing the average number of goals scored in the tournament, it may be more important to...

Mechanism of Cardiac Arrhythmias
2.3K
Arrhythmias are irregular heart rhythms occurring when the heart's electrical impulses become abnormal. These disturbances can lead to various symptoms, depending on their severity and the underlying cause. Some common factors contributing to arrhythmias include hypoxia, ischemia, electrolyte imbalances, excessive catecholamine exposure, drug toxicity, and muscle overstretching. Arrhythmias can be classified into two main types based on the rate and site of origin of abnormal heart rhythms.

Excess Pressure Inside a Drop and a Bubble
3.5K
The shape of a small drop of liquid can be considered spherical, neglecting the effect of gravity. This drop can further be considered as two equal hemispherical drops put together due to surface tension. The forces acting on the spherical drop are due to the pressure of the liquid inside the drop, the pressure due to air outside the drop, and the force due to the surface tension acting on the two hemispherical drops.

Atomic Weight
14.1K
Protons and neutrons have approximately the same mass, about 1.67 × 10-24 grams. Scientists arbitrarily define this amount of mass as one atomic mass unit (amu) or one Dalton. Electrons are much smaller in mass than protons, weighing only 9.11 × 10-28 grams, or about 1/1800 of an atomic mass unit. As a result, they do not contribute much to an element's overall atomic mass. This means that, when considering atomic mass, it is customary to ignore the mass of any electrons and...
