From the Guidelines
Nebulizer treatment is not recommended for tachycardia, as the primary treatment involves vagal maneuvers, medications like adenosine, beta-blockers, calcium channel blockers, or antiarrhythmics. The treatment for tachycardia depends on the specific type and underlying cause, and the most recent and highest quality study 1 recommends vagal maneuvers, IV adenosine, verapamil, and diltiazem as first-line treatment strategies in the termination of narrow-complex tachycardias.
Some key points to consider in the treatment of tachycardia include:
- Vagal maneuvers like the Valsalva maneuver or carotid sinus massage can be effective for supraventricular tachycardia
- Adenosine (6mg rapid IV push, followed by 12mg if needed) is often the next step due to its short half-life and effectiveness in interrupting abnormal electrical pathways
- For ventricular tachycardia, amiodarone or electrical cardioversion may be necessary
- Long-term management might include daily oral medications like metoprolol (25-100mg twice daily), propranolol (10-40mg three times daily), or diltiazem (120-360mg daily in divided doses), depending on the type of tachycardia
It's also important to note that addressing underlying causes such as hyperthyroidism, anemia, or electrolyte imbalances is equally important for comprehensive management, as stated in 1. Additionally, catheter ablation by experienced operators is recommended as a first-line treatment in symptomatic patients with idiopathic left VTs, according to 1. However, nebulizer treatment is not a recommended treatment option for tachycardia, and treatment should be guided by the most recent and highest quality evidence.

From the Research
Treatment for Tachycardia
- The primary treatment for tachycardia depends on the type and severity of the condition, as well as the patient's overall health 2.
- Beta-adrenergic blockers are often the drugs of choice for persistent sinus tachycardia, while verapamil and/or digitalis may be used to suppress paroxysmal sinus tachycardias 2.
- For atrial premature contractions, quinidine or disopyramid may be effective, while lidocain is often used to treat ventricular tachycardias 2.
- Calcium channel blockers, such as verapamil, can be used to reduce blood pressure and treat certain types of tachycardia, including supraventricular tachycardias and atrial fibrillation 3, 4.
Acute Treatment
- For acute treatment of tachycardia, adenosine, ajmaline, and amiodarone may be used, and in cases of hemodynamic instability, electrocardioversion may be necessary 5.
- Catheter ablation is often the treatment of choice for supraventricular tachycardias, atrial flutter, and idiopathic ventricular tachycardias 5.
Long-term Management
- Long-term management of tachycardia may involve antiarrhythmic drug therapy, catheter ablation, or implantable cardioverter-defibrillator (ICD) therapy, depending on the underlying cause and severity of the condition 5, 6.
- Anticoagulant therapy may also be necessary for patients with atrial fibrillation, depending on their risk score analysis 5.
