pre-excitation

pre-excitation

premature excitation of a portion of the ventricle caused by stimuli passing along one of the auxiliary pathways of cardiac stimulation that are not subject to the same physiological delays as the A-V node. Characterized electrocardiographically by a short P-R interval and a wide QRS interval. See also accessory tract atrioventricular conduction, wolff-parkinson-white syndrome, lown-ganong-levine syndrome.

The company said ESMOCARD is indicated for supraventricular tachycardia (except for pre-excitation syndromes) and for the rapid control of the ventricular rate in patients with atrial fibrillation or atrial flutter in perioperative, postoperative, or other circumstances where short-term control of the ventricular rate with a short-acting agent is desirable.
Wolf-Parkinson and White Syndrome (WPW) is the most widespread type of pre-excitation syndrome which is associated with an accessory AV connection, called Kent Bundle.
The next most common diagnoses were related to primary rhythm issues such as aborted sudden cardiac death, palpitations, ectopic beats, atrial fibrillation, ventricular pre-excitation or ventricular tachycardia (24.

Starting with deep analysis then moving to quick diagnosis, they consider such aspects as how to take an ECG recording, handshakes with "electrical axis," sinus tachycardia, some details of fascicular blocks, and important pre-excitation syndromes.
3] The classical pre-excitation syndrome was first described by Wolf-Parkinson and White in 1930 as an ECG, consisting of a "functional bundle branch block and short PR interval occurring in otherwise healthy, young people with paroxysms of tachycardia".

These include Holter monitoring (quantification of extrasystoles and identification of tachy-and bradyarrythmias), cardiac magnetic resonance imaging (MRI) scan (ARVC, HCM, and myocarditis), tissue Doppler (ARVC), sodium channel blocker challenge (Brugada syndrome), and adenosine challenge for pre-excitation (familial risk of WPW syndrome and supraventricular tachycardia).
