In patients with prior myocardial infarction and recurrent episodes of symptomatic sustained ventricular tachycardia (VT), or who present with VT or ventricular fibrillation storm and have failed or are intolerant of amiodarone (Level of Evidence B-R) or other antiarrhythmic medications (Level of Evidence B-NR), catheter ablation is recommended.

Ventricular tachycardia is defined as three or more consecutive ventricular premature beats. In other cases, such as Supraventricular Tachycardia, Atrial Fibrillation, or bradydysrhythmias, the risk is related to the likelihood of recurrence, and the likelihood that recurrence may result in alteration or loss of consciousness. << /ca 1 For patients who require arrhythmia suppression for symptoms or declining ventricular function suspected to be due to frequent premature ventricular complexes (generally >15% of beats and predominately of one morphology) and for whom antiarrhythmic medications are ineffective, not tolerated, or not the patient’s preference, catheter ablation is useful (Level I).

Congenital heart defects (CHD) occur when the heart or blood vessels near the heart don't develop normally before birth. Most specialists don't know why they occur, but they're always researching. In patients with heart failure (HF) with reduced ejection fraction (left ventricular ejection fraction [LVEF] ≤40%), treatment with a beta-blocker, a mineralocorticoid receptor antagonist, and either an angiotensin-converting enzyme inhibitor or an angiotensin-receptor blocker, or an angiotensin receptor-neprilysin inhibitor is recommended to reduce SCD and all-cause mortality (Class I). Clinical Characteristics 1.1 Definition and prevalence Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT) is an inherited arrhythmia syndrome, characterized by polymorphic ventricular tachycardia induced by adrenergic stress. trailer

To determine the clinical status, the occurrence of chronic ambulatory arrhythmias, and the prognosis of patients with exercise-induced ventricular tachycardia, 26 patients with ventricular tachycardia during or immediately following exercise on a treadmill were evaluated. The mortality rate within two years is reported to be higher than 30 percent in patients with nonsustained ventricular tachycardia on Holter monitoring and impaired left ventricular function.6 Two .
