31. Also, ventricular fibrillation frequently occurs below and asystole below. 32. Her death certificate lists ventricular fibrillation , or an irregular heart rhythm, as the cause of death. 33. In addition, ventricular tachycardia can quickly degenerate to ventricular fibrillation and death and merits different consideration. 34. The conditions are ventricular fibrillation and ventricular tachycardia, and both involve the ventricles of the heart. 35. Cardiac arrest can be caused by a sudden problem with the heart's rhythm _ ventricular fibrillation . 36. The first electrocardiogram recording of ventricular fibrillation was by August Hoffman in a paper published in 1912. 37. Spontaneous conversion of ventricular fibrillation to a more benign rhythm is rare in all but small animals. 38. Ultimately, ventricular tachycardia leads to ventricular fibrillation . 39. Although the most frequent cause of sudden cardiac death is ventricular fibrillation , other causes include the following: 40. Improved versions were programmed to be able to detect ventricular tachycardia, often a forerunner of ventricular fibrillation .
