What should be given to lower a sustained heart rate of tachycardia?

From the Guidelines

For a patient with a sustained heart rate in the 180s, beta-blockers or calcium channel blockers should be given to lower the heart rate. First-line options include intravenous metoprolol (5 mg slow IV push, which can be repeated up to 3 times at 5-minute intervals) or diltiazem (0.25 mg/kg IV over 2 minutes, followed by a second dose of 0.35 mg/kg if needed) 1. The choice of medication depends on the underlying cause of tachycardia, presence of structural heart disease, and patient comorbidities. Some key points to consider when choosing a medication include:

• The patient's hemodynamic stability: if unstable, immediate synchronized cardioversion may be necessary instead of medication.
• The presence of contraindications to beta-blockers or calcium channel blockers, such as heart failure or bronchospasm.
• The potential for interactions with other medications the patient is taking.
• The need for ongoing monitoring and adjustment of the medication dose as needed.

It's also important to note that other medications, such as amiodarone, may be used in certain situations, such as in patients with contraindications to beta-blockers or calcium channel blockers 1. However, the use of these medications should be guided by the patient's specific clinical situation and the potential risks and benefits of each medication. Overall, the goal of treatment is to slow the heart rate and improve the patient's symptoms, while also minimizing the risk of adverse effects. Some key medications and their dosing regimens include:

• Metoprolol: 5 mg slow IV push, repeated up to 3 times at 5-minute intervals.
• Diltiazem: 0.25 mg/kg IV over 2 minutes, followed by a second dose of 0.35 mg/kg if needed.
• Amiodarone: 150 mg IV over 10 minutes, followed by an infusion of 1 mg/min for 6 hours. These medications work by blocking specific receptors or ion channels in the heart, reducing the conduction of electrical impulses and slowing the heart rate 1. Before administering any medication, it's essential to ensure the patient is hemodynamically stable; if unstable, immediate synchronized cardioversion may be necessary instead of medication. The patient's response to treatment should be closely monitored, and adjustments made as needed to achieve the desired heart rate and minimize adverse effects. In addition to medication, other treatments, such as vagal maneuvers or electrical cardioversion, may be used in certain situations to help slow the heart rate and improve the patient's symptoms 1. The choice of treatment will depend on the patient's specific clinical situation and the potential risks and benefits of each option. It's also important to consider the potential risks and benefits of each medication, as well as the patient's individual characteristics and medical history, when making treatment decisions. Some potential risks and benefits to consider include:
• The risk of adverse effects, such as hypotension or bradycardia, with beta-blockers or calcium channel blockers.
• The potential for interactions with other medications the patient is taking.
• The need for ongoing monitoring and adjustment of the medication dose as needed.
• The potential benefits of slowing the heart rate and improving the patient's symptoms. Overall, the goal of treatment is to improve the patient's symptoms and minimize the risk of adverse effects, while also considering the patient's individual characteristics and medical history. The patient's response to treatment should be closely monitored, and adjustments made as needed to achieve the desired heart rate and minimize adverse effects. Some key factors to consider when monitoring the patient's response to treatment include:
• The patient's heart rate and rhythm.
• The presence of any adverse effects, such as hypotension or bradycardia.
• The patient's symptoms, such as chest pain or shortness of breath.
• The need for ongoing adjustment of the medication dose or addition of other treatments. By considering these factors and individualizing treatment to the patient's specific clinical situation, it's possible to improve the patient's symptoms and minimize the risk of adverse effects.

From the FDA Drug Label

Verapamil Hydrochloride Injection, USP is indicated for the following: • Temporary control of rapid ventricular rate in atrial flutter or atrial fibrillation except when the atrial flutter and/or atrial fibrillation are associated with accessory bypass tracts (Wolff-Parkinson-White (W-P-W) and Lown-Ganong-Levine (L-G-L) syndromes) About 70% of patients with atrial flutter and/or fibrillation with a faster ventricular rate respond with a decrease in ventricular rate of at least 20%. Slowing of the ventricular rate in patients with atrial fibrillation/flutter lasts 30 to 60 minutes after a single injection

To lower a heart rate of 180s, verapamil (IV) can be given, as it is indicated for the temporary control of rapid ventricular rate in atrial flutter or atrial fibrillation 2.

• Key considerations:
  • Verapamil should not be used in patients with atrial flutter and/or atrial fibrillation associated with accessory bypass tracts.
  • The initial use of verapamil should be in a treatment setting with monitoring and resuscitation facilities.
• Expected outcome: About 70% of patients can expect a decrease in ventricular rate of at least 20%, lasting 30 to 60 minutes after a single injection.

From the Research

Treatment for Sustained Heart Rate of 180s

To lower a sustained heart rate of 180s, the following treatments can be considered:

• Vagal maneuvers as the first line of treatment 3, 4, 5
• Adenosine administration in increasing doses of 6,12, and 18 mg until sinus rhythm is achieved or transient atrioventricular block is recorded 3
• High-dose adenosine (up to 36 mg) may be considered for refractory supraventricular tachycardia 6
• Beta-blockers and/or calcium channel blockers may be used acutely or for long-term suppressive therapy 4, 5
• Synchronized cardioversion is recommended for hemodynamically unstable patients 5

Adenosine Administration

Adenosine is commonly used to treat supraventricular tachycardia, and its administration is recommended as follows:

• Initial dose of 6 mg, followed by 12 mg and 18 mg if necessary 3
• High-dose adenosine (up to 36 mg) may be considered for refractory cases 6
• Adenosine is effective in converting narrow-complex tachycardias to sinus rhythm, with a success rate of 74% in one study 3
• Adenosine is also effective in prehospital settings, with a conversion rate of 90.3% in one study 7

Long-term Management

Long-term management of supraventricular tachycardia depends on several factors, including frequency of symptoms, risk stratification, and patient preference 4, 5. Options for long-term management include:

• Conservative management for patients with rare symptoms and low risk
• Catheter ablation, which has a high success rate and is recommended as the first-line method for long-term management of recurrent, symptomatic paroxysmal SVT 5
