概括
TpTe间隔是评估儿童心律失常风险的关键指标,特别是那些体重异常的儿童. 与QT间隔一起测量这个参数可以改善恶性心室节律失常的风险分层.
科学领域:
- 心脏病学 心脏病学
- 儿科 儿科 儿科
- 临床电生理学 临床电生理学
背景情况:
- 电心电图复极异常,包括延长的QT和TpTe间隔,对于识别恶性心室失常风险至关重要.
- 评估儿童的这些参数,考虑到体重变化,对于准确的诊断和风险分层至关重要.
研究的目的:
- 为了比较有或没有心律失常的儿童的心电复极化参数,按体重分层.
- 调查TpTe,QTp和纠正的QT间隔 (QTcB,QTcF) 的诊断值,在患有不同体重指数 (BMI) 和心律失常类型的儿科患者中.
主要方法:
- 再极化参数 (TpTe,QTp,QTcB,QTcF) 从12个心电图中的V5度进行测量.
- 患有心室和心室以上心律不整的儿童,按正常和异常体重分类 (使用BMI和科尔指数),与体重正常的对照组进行了比较.
主要成果:
- 在患有心室失常症的超重儿童中,TpTe和QTcF间隔与患有心室失常症的儿童相比显著更长.
- 与心室失常症相比,在患有心室失常症的超重儿童中观察到显著的TpTe间隔延长.
- 在所有五组中都发现了TpTe间隔的统计学上显著差异 (p < 0.0001),突出了对心律失常和体重状况的敏感性.
结论:
- 在患有心室节律失常的儿童中,TpTe间隔显著长于患有心室节律失常或没有心室节律失常的儿童,无论体重如何.
- 对于患有心律失常的儿童,除了QT间隔外,还建议例行测量TpTe间隔.

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
611
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...
