In general, it is an irregular, narrow complex rhythm. However, it may show wide QRS complexes on the ECG if a bundle branch block is present. At high rates, the QRS complex may also become wide due to the Ashman phenomenon. It may be difficult to determine the rhythm's regularity when the rate exceeds 150 beats per minute.
A 12-lead ECG showing paroxysmal supraventricular tachycardia at about 180 beats per minute. Subtypes of SVT can often be distinguished by their electrocardiogram (ECG) characteristics. Most have a narrow QRS complex, although, occasionally, electrical conduction abnormalities may produce a wide QRS complex that may mimic ventricular ...
If a person with WPW experiences episodes of atrial fibrillation, the ECG shows a rapid polymorphic wide-complex tachycardia (without torsades de pointes). This combination of atrial fibrillation and WPW is considered dangerous, and most antiarrhythmic drugs are contraindicated. [citation needed]
Ashman beats are described as wide complex QRS complexes that follow a short R-R interval preceded by a long R-R interval. [3] This short QRS complex typically has a right bundle branch block morphology and represents an aberrantly conducted complex that originates above the AV node, rather than a complex that originates in either the right or left ventricle.
The QRS duration must be more than 100 ms (incomplete block) or more than 120 ms (complete block). [9] There should be a terminal R wave in lead V 1 (often called "R prime," and denoted by R, rR', rsR', rSR', or qR). There must be a prolonged S wave in leads I and V 6 (sometimes referred to as a "slurred" S wave).
Accelerated idioventricular rhythm (AIVR) at a rate of 55/min presumably originating from the left ventricle (LV). Note the typical QRS morphology in lead V1 characteristic of ventricular ectopy from the LV. Monophasic R-wave with smooth upstroke and notching on the downstroke (i.e., the so-called taller left peak or "rabbit-ear".) Specialty
Ventricular tachycardia is a regular rhythm with a rate of 140-250 bpm, there are no P waves and the main feature is a wide QRS complex (0.12 and greater) Ventricular fibrillation has no p waves or QRS complexes, there are only wavy irregular deflections throughout the heart rhythm, at this point the heart would have a rate of 0 and be ...
This is in contrast to a permanent dysfunction of the electrical pathways that produces wide QRS complexes in one of the above patterns or combinations of patterns (ie, bifascicular block). In the context of atrial fibrillation , the Ashman phenomenon is a form of aberrancy.
