5 天之前 · 心房粗動(Atrial flutter) 心房粗動は心房拍数240〜440拍/分の規則的波形を有するマクロリエントリー性頻拍です。 マクロは「大きい」を意味しており、一般的には三尖弁の周囲を大きなリエントリー回路として興奮が旋...

6 天之前 · Review in-depth clinical information, latest medical news, and guidelines about cardiac arrhythmias, including atrial fibrillation, paroxysmal tachycardia, ventricular tachycardia, and ventricular fibrillation.

5 天之前 · After the pulmonary vein isolation in 179 patients with atrial fibrillation (AF), antegrade and retrograde propagation maps were created for all patients. Atrial burst pacing, induced atrial tachycardia (AT) in 38 patients. Among those patients, peri-mitral AT (PMAT) was induced in …

4 天之前 · Patients with atrial flutter exhibit a typical ECG pattern of saw-toothed flutter waves of atrial contractions with a 2:1 to 4:1 ventricular response. Patients with ventricular tachycardia typically have a wide QRS complex tachycardia with a regular rhythm.

4 天之前 · Paroxysmal supraventricular tachycardia refers to a sudden, rapid heart rate originating from a point above the ventricles, often in the atria or the AV node. PSVT episodes typically begin and end abruptly and can last from a few seconds to several hours.

6 天之前 · Atrial systole is an essential component of the cardiac cycle. It is primarily triggered by the electrical impulses generated by the SA node, and its timing is influenced by both intrinsic factors (such as the automaticity of the SA node) and extrinsic factors (such as physical activity and hormonal changes).

6 天之前 · The goal of this activity is for learners to be better able to examine novel approaches for paroxysmal supraventricular tachycardia (PSVT), including their mechanism of action (MOA); to evaluate the latest clinical safety and efficacy data for novel treatment strategies for PSVT; and to discuss the potential value of new therapies for improved ...

5 天之前 · Supraventricular tachycardia (increased heart rate) is initiated in the atria and arises from a number of conditions, including an increase in sinoatrial node impulse rate that normally occurs during conditions of high excitation, such as hyperthyroidism or exercise.

5 天之前 · It can also be caused due to an arrhythmia of any type. Arrhythmias that cause tachycardia include like atrial fibrillation and atrial flutter. Medications can be responsible for causing tachycardia in children too. They do so either through induction of arrhythmia or through the discharge of catecholamines.

4 天之前 · AT = atrial tachycardia; CPVT = catecholaminergic polymorphic ventricular tachycardia; LQTS = long-QT syndrome; SCD = sudden cardiac death. We report hereby a novel TECRL pathogenic variant in a family of European ancestry.
