概括
在心转动后,中区域性前性尿素 (MR-proANP) 水平的升高独立地预测了前性的复发. 这一发现可能有助于在一年内识别高风险的AF复发患者.
科学领域:
- 心脏病学
- 生物标志物
- 电生理学
背景情况:
- 在电心转移后,心房动的复发是常见的.
- 需要预测性标记来维持鼻节律.
- 研究了大脑尿素的N终端前激素 (NT-proBNP) 和其他生物标志物.
研究的目的:
- 评估MR-proANP,可溶性ST2 (sST2) 和B型尿素 (BNP) 在持续性AF电动心脏转移成功后的一年内维持鼻腔节律的预测能力.
- 为了确定AF复发预测的新生物标志物.
主要方法:
- 这是一项前性的多中心观察研究.
- 包括经过电动心脏转换的持续性AF患者.
- 在心脏转换前,在周围静脉血液中测量了MR-proANP,sST2和BNP.
- 主要终点:通过心电图或霍尔特监测定义的12个月内AF复发.
主要成果:
- 包括61名患者,83. 6%的患者在心转动后获得了鼻腔节律.
- 复发性AF患者的MR- proANP水平 (314. 45 pmol/ L) 与没有复发性AF患者的MR- proANP水平 (214. 50 pmol/ L) 显著更高 (p < 0. 01).
- 一个MR-proANP的值为311.5 pmol/ L最好的预测AF复发 (HR 4. 74). sST2和BNP没有预测价值.
结论:
- 增加的MR-proANP水平可以独立预测心转动后一年内AF的复发.
- 作为一种有价值的生物标志物,MR- proANP可用于识别高风险的AF复发患者.
- 需要在更大的研究中进行进一步验证.

Dysrhythmias VI: Management of Dysrhythmias
106
Dysrhythmia management involves a multifaceted approach, incorporating pharmacological treatments, medical procedures, surgical interventions, lifestyle modifications, and patient education.Pharmacological ManagementAntiarrhythmic Drugs:Class I (Sodium Channel Blockers): This class includes quinidine and procainamide, which reduce the speed of impulse conduction in the heart, stabilize the cardiac membrane, and control arrhythmias. Quinidine and procainamide are Class IA agents that prolong the...

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias
160
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...

Pulse rhythm
925
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

Dysrhythmias IV: Characteristics of Bradyarrhythmias
118
Bradyarrhythmias are cardiac rhythm disorders characterized by a slower-than-normal heart rate, typically defined as fewer than 60 beats per minute. Some of which are discussed here:Sinus BradycardiaSinus bradycardia presents a heart rate lower than 60 beats per minute, with a regular rhythm originating from the SA node. The ECG typically shows normal P waves preceding each QRS complex, a normal PR interval (0.12 to 0.20 seconds), and a normal QRS duration (0.06 to 0.10 seconds).First-Degree AV...

Disturbances in Heart Rhythm
1.2K
Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow heart...

Dysrhythmias V: Evaluating Dysrhythmias
117
Dysrhythmias, also known as arrhythmias, are disturbances in the heart's rhythm that range from benign to life-threatening. A thorough evaluation is crucial for appropriate management and involves a comprehensive medical history, physical examination, and various diagnostic tests.Medical HistorySymptoms: Collect detailed information on palpitations, dizziness, syncope, chest pain, and fatigue. Note their onset, frequency, and triggers.Previous Cardiac Issues: Document any history of heart...
