Different ECG patterns 2

The ECG pattern for VF is characterized by a fast heart rate of more than 350 beats per minute, along with chaotic irregular deflections of varying amplitude, with no identifiable P waves, QRS complexes, or T waves.VF often arises from ventricular tachycardia and is the most common cause of sudden cardiac death. While its underlying mechanisms are still not fully understood, it is generally thought to be caused by a combination of electrical and mechanical factors. The electrical factors are thought to include abnormal myocardial ion channel function, changes in the cell-to-cell coupling, and abnormalities in cardiac autonomic nervous system function. The mechanical factors are thought to includ.شاهد المزيد
