2025年1月5日 · Ventricular tachycardia: usually above ~120 b/m. A heart rate close to or higher suggests a non-sinus mechanism. Usually, max heart rate would only be reached under marked physiological stress. Max sinus heart rate would also be expected to be accompanied by AV nodal stimulation (causing a relatively low PR interval).

Supraventricular tachycardia (SVT) is a common cause of hospital admissions and can cause significant patient discomfort and distress. The most common SVTs include atrioventricular nodal re-entrant tachycardia, atrioventricular re-entrant tachycardia and atrial tachycardia.

2024年10月8日 · The term supraventricular tachycardia (SVT) refers to any tachydysrhythmia arising from above the level of the Bundle of His, and encompasses regular atrial, irregular atrial, and regular atrioventricular tachycardias

2025年3月17日 · Supraventricular tachycardia (SVT) are a group of tachycardias in which at least a structure above the bundle of His is necessary for its continuance. Supraventricular tachycardias include a number of disorders, atrioventricular nodal reentrant tachycardia and atrioventricular reentry tachycardia being the most frequent.

2015年5月5日 · Supraventricular tachycardia (SVT): rapid heart rate originating above/within the atrioventricular (AV) node; not a diagnosis, but a starting point for diagnosis. Sinus tachycardia: focal tachycardia from the sinoatrial node, usually regular.

2020年2月11日 · Flecainide or propafenone should be considered for prevention of SVT in patients with WPW syndrome and without ischemic or structural heart disease (Class IIa). SVTs have been reported as risk factors for sudden cardiac death in patients with adult congenital heart disease (ACHD).

2015年9月23日 · Paroxysmal SVT is a regular, and typically narrow complex tachycardia that is characterized by sudden onset and termination. Its causes include atrioventricular nodal reentrant tachycardia (AVNRT), orthodromic atrioventricular reentrant tachycardia (AVRT) utilizing an accessory pathway, and atrial tachycardia (AT).

2021年1月6日 · SVT Hits A number of events and runs from 2019 have large numbers of SVT hits. Some appear to be pathological whereas others appear to be simply increased occupancy. Fitting the APV25 waveforms for these hits consumes large amounts of CPU time. Handling such large numbers of hits also drastically slows the track- finding pattern recognition.

2019年8月31日 · ESC Clinical Practice Guidelines aim to present all the relevant evidence to help physicians weigh the benefits and risks of a particular diagnostic or therapeutic procedure on Supraventricular Arrhythmias. They should be essential in everyday clinical decision making.

Supraventricular tachycardia (SVT) refers to when abnormal electrical signals from above (supra-) the ventricles cause a fast heart rate (tachycardia). Normally, the electrical signals of the heart start in the sinoatrial node. The sinoatrial node is the heart’s natural pacemaker, dictating when the …
