If VT is not treated, it can lead to cardiac arrest, which is when the heart stops beating. In fact, VT is the most common cause of sudden cardiac arrest. Patients may feel a fluttering in the chest, chest pain, shortness of breath and dizziness or lightheadedness as a result. Q: How is VT typically treated?

However, he suddenly developed a series of malignant ventricular arrhythmias. He required multiple defibrillations within a period of a few hours. Below are printouts of some of the arrhythmias recorded. This time, the arrhythmia did not spontaneously terminate — but rather degenerated to VFib, requiring defibrillation.

Introduction Sudden cardiac arrest is a major cause of morbidity and mortality worldwide and remains a major public health problem for which better non-invasive prediction tools are needed. Primary preventive therapies, such as implantable cardioverter defibrillators, are not personalized and not predictive.

Alternatively, it also helps enhance arrhythmia management with coronary artery disease. Along with it, a guideline-based algorithm helps identify implantable cardioverter defibrillators.

Prior to Mizusawa's study, it was thought that the incidence of syncope, arrhythmia, or SCD in this cohort was low [7]. In light of the risk of arrhythmia events observed in the Mizusawa trial, a formal EP study might be reasonable to obtain in those with fever induced asymptomatic Brugada ECG changes to help risk stratify these patients.
