From the Guidelines
Ventricular trigeminy should be treated with catheter ablation, as it is a recommended approach for patients with frequent symptomatic PVCs or NSVT, especially those with left ventricular dysfunction 1. When considering treatment options for ventricular trigeminy, it is crucial to evaluate the patient's symptoms and underlying heart disease. According to the 2015 ESC guidelines 1, catheter ablation is a recommended treatment for patients with frequent symptomatic PVCs or NSVT, particularly those with left ventricular dysfunction. Some key points to consider in the management of ventricular trigeminy include:
- Evaluating the patient's symptoms and underlying heart disease to determine the need for treatment 1
- Considering catheter ablation as a treatment option for patients with frequent symptomatic PVCs or NSVT, especially those with left ventricular dysfunction 1
- Addressing underlying causes, such as correcting electrolyte abnormalities, reducing caffeine and alcohol intake, and managing stress 1
- Using antiarrhythmic drugs like amiodarone as an alternative treatment option 1 It is essential to prioritize the patient's morbidity, mortality, and quality of life when making treatment decisions for ventricular trigeminy, and catheter ablation is a recommended approach based on the most recent and highest-quality evidence 1.

From the Research
Treatment Options for Ventricular Tachyarrhythmias
- Beta-blockers are used to treat acquired heart failure in adults and have been shown to have anti-arrhythmic effects 2, 3
- The dose-dependent association between beta-blocker therapy and risk of ventricular tachyarrhythmias, heart failure hospitalizations, and death has been investigated, with results suggesting a dose-dependent effect 4
- Beta-blockers such as metoprolol and carvedilol have been shown to reduce the risk of heart failure hospitalizations and death in primary prevention implantable cardioverter-defibrillator recipients 4
Mechanisms of Beta-Blocker Therapy
- Beta-blockers work by reducing sympathetic activity, which plays an important role in modulation of cardiac rhythm 2
- The molecular mechanisms of β-adrenergic action in the heart, the cellular and tissue level cardiac responses to β-adrenergic stimulation, and the clinical use of β-blockers as antiarrhythmic agents have been reviewed 2
- Beta-blockers have been shown to have anti-arrhythmic effects in the treatment of chronic congestive heart failure, with a reduction in sudden death and ventricular arrhythmias 3
Specific Beta-Blockers and Their Effects
- Metoprolol has been shown to have deleterious effects on right ventricular function in mdx mice, a model for Duchenne Muscular Dystrophy 5
- Carvedilol and metoprolol have been compared in terms of their effects on ventricular tachyarrhythmias, heart failure hospitalizations, and death, with no significant difference found between comparable doses of the two drugs 4
