Postural orthostatic tachycardia syndrome (POTS, also called postural tachycardia syndrome) is a medical problem. When a person has POTS, their heart beats faster than normal when they stand up. POTS may also cause many other symptoms .
Junctional ectopic tachycardia (JET) is a rare syndrome of the heart that manifests in patients recovering from heart surgery. [1] It is characterized by cardiac arrhythmia , or irregular beating of the heart, caused by abnormal conduction from or through the atrioventricular node (AV node).
Sustained atrial tachycardia can lead to a tachycardia-induced cardiomyopathy. Differs from sinus tachycardia in that the impulses are generated by an ectopic focus somewhere within the atrial myocardium rather than the sinus node.
Reentry can produce single ectopic beats, or it can trigger paroxysmal tachycardia. Triggered beats are considered to be due to after-depolarizations triggered by the preceding action potential. These are often seen in patients with ventricular arrhythmias due to digoxin toxicity and reperfusion therapy after myocardial infarction (MI).
视频字幕. 心跳过速（tachycardia，tachyarrhythmia）又称心动过速 [1] 、心搏过速 [2] ，是指心跳速度超出正常范围。 一般來說，成年人在靜止狀態下心跳达到每分钟一百次以上即屬心跳過速 [3] 。
Dec 15, 2023 · The goals of tachycardia treatment are to slow a rapid heartbeat and to prevent future episodes of a fast heart rate. If another health condition is causing tachycardia, treating the underlying problem may reduce or prevent episodes of a fast heartbeat. Slowing a fast heart rate. A fast heart rate may correct itself.
Wide-complex tachycardia. Assume any wide-complex tachycardia is ventricular tachycardia until proven otherwise (it is safer to incorrectly assume a ventricular dysrhythmia than supraventricular tachycardia with abberancy) Regular Monomorphic ventricular tachycardia; PSVT with aberrant conduction: PSVT with bundle branch block^ PSVT with ...
