Overview

There are no recommended therapeutic interventions for the management of [disease name].

OR

[name of intervention] is not the first-line treatment option for patients with [disease name]. [name of intervention] is usually reserved for patients with either [indication 1], [indication 2], and/or [indication 3].

OR

The mainstay of treatment for [disease name] is medical therapy/surgery. [Name of intervention] is usually reserved for patients with either [indication 1], [indication 2], and/or [indication 3].

OR

The feasibility of [name of intervention] depends on the stage of [disease or malignancy] at the time of diagnosis.

OR

[Name of intervention] is the mainstay of treatment for [disease or malignancy].

Indications

The mainstay of treatment for TT is medical therapy.

Overview

Radiofrequency ablation is useful for treating patients with high frequency of premature ventricular contraction episodes.

Ablation

Recent studies have shown that those subjects who have an extremely high occurrence of PVCs (several thousand a day) can develop dilated cardiomyopathy. In these cases, if the PVCs are reduced or removed by ablation therapy, the cardiomyopathy usually regresses.[1][2]

2017 AHA/ACC/HRS Guideline for Management of Patients with Ventricular Arrhythmias and the Prevention of Sudden Cardiac Death (DO NOT EDIT)[3]

Recommendations for Autonomic Modulation

Class IIb
1. In patients with VT/VF storm in whom a beta blocker, other antiarrhythmic medications, and catheter ablation are ineffective, not tolerated, or not possible, cardiac sympathetic denervation may be reasonable (Level of Evidence: C-LD).[4][5][6]

Recommendations for Management of Cardiac Arrest

Class I
1. CPR should be performed in patients in cardiac arrest according to published basic and advanced cardiovascular life support algorithms (Level of Evidence: A).[7][8][9]

2. In patients with hemodynamically unstable VA that persist or recur after a maximal energy shock, intravenous amiodarone should be administered to attempt to achieve a stable rhythm after further defibrillation (Level of Evidence: A). [7][10][11]

3. Patients presenting with VA with hemodynamic instability should undergo direct current cardioversion (Level of Evidence: A).[7][8][9]

4. In Patients with polymorphic VT or VF with ST-elevation MI, angiography with emergency revascularization is recommended (Level of Evidence: B-NR).[12][13][14][15]

5. Patients with a wide-QRS tachycardia should be presumed to have VT if the diagnosis is unclear (Level of Evidence: C-EO).

Class IIa
1. In patients with hemodynamically stable VT, administration of intravenous procainamide can be useful to attempt to terminate VT (Level of Evidence: A).[16][17][18]

2. In patients with a witnessed cardiac arrest due to VF or polymorphic VT that is unresponsive to CPR, defibrillation, and vasopressor therapy, intravenous lidocaine can be beneficial (Level of Evidence: B-R).[7][10][19][20][21]

3. In patients with polymorphic VT due to myocardial ischemia, intravenous beta blockers can be useful(Level of Evidence: B-R).[22][23]

4. In patients with a recent MI who have VT/VF that repeatedly recurs despite direct current cardioversion and antiarrhythmic medications (VT/VF storm), an intravenous beta blocker can be useful(Level of Evidence: B-NR).[23][24]

Class IIb
1. In patients in cardiac arrest, administration of epinephrine (1 mg every 3 to 5 minutes) during CPR may be reasonable (Level of Evidence: A).[7][25][26][27][28][29][30]

2. In patients with hemodynamically stable VT, administration of intravenous amiodarone or sotalol may be considered to attempt to terminate VT (Level of Evidence: B-R).[19][18][31][32]


Class III: No Benefit
1. In patients with cardiac arrest, administration of high-dose epinephrine (>1 mg boluses) compared with standard doses is not beneficial (Level of Evidence: A).[33][27]

2. In patients with refractory VF not related to torsades de pointes, administration of intravenous magnesium is not beneficial (Level of Evidence: A).[34][35]

Class III: Harm
1. In patients with suspected AMI, prophylactic administration of lidocaine or high-dose amiodarone for the prevention of VT is potentially harmful (Level of Evidence: B-R).

[36][37]

2. In patients with a wide QRS complex tachycardia of unknown origin, calcium channel blockers (eg, verapamil and diltiazem) are potentially harmful(Level of Evidence: C-LD).[38][39]
