WebAn arrhythmia is an abnormal heart rhythm. Your heart is controlled by a conduction system which sends out electrical impulses. This causes a heartbeat. Arrhythmias are caused by a problem in this conduction system, which can make your heart beat too slowly, too quickly, or in an irregular way. There are different types of arrhythmia, the most ... WebA ventricular beat follows each sinus beat and the coupling interval between the ventricular beat and the previous sinus QRS complex is constant (ie, fixed coupling interval). As shown in Figure 4, a ventricular trigeminy is present when two sinus beats are followed by the VPB. Thus, every third beat is a VPB. cheap ar15 kitsWebApr 30, 2024 · During an episode of SVT, the heart beats about 150 to 220 times a minute, but it can occasionally beat faster or slower.
