A fusion beat occurs when electrical impulses from different sources act upon the same region of the heart at the same time. [1] If it acts upon the ventricular chambers it is called a ventricular fusion beat , whereas colliding currents in the atrial chambers produce atrial fusion beats .
Capture beats (normal QRS complex in between when the heart picks up the sinus rhythm from the impulses generated by the SA node), fusion beats (due to the fusion of the abnormal and the normal QRS complexes), which has a unique morphology; Positive or negative concordance; Extreme axis deviation or northwest axis (axis between -90 and +180 ...
Ventricular escape beats occur when the rate of electrical discharge reaching the ventricles (normally initiated by the heart's sinoatrial node (SA node), transmitted to the atrioventricular node (AV node), and then further transmitted to the ventricles) falls below the base rate determined by the rate of Phase 4 spontaneous depolarisation of ventricular pacemaker cells. [1]
The first experiments used beams of positives and negatives as fuel, and demonstrated energy capture at a peak efficiency of 65 percent and a minimum efficiency of 50 percent. [7] [8] The following experiments involved a true plasma direct converter that was tested on the Tandem Mirror Experiment (TMX), an operating magnetic mirror fusion
Junctional tachycardia is a form of supraventricular tachycardia characterized by involvement of the AV node. [1] It can be contrasted to atrial tachycardia.It is a tachycardia associated with the generation of impulses in a focus in the region of the atrioventricular node due to an A-V disassociation. [2]
