With the rise in home monitoring devices, how should we approach asymptomatic NSVT detected in healthy individuals with no prior cardiac history and with low risk cardiac profile?

With home monitoring devices, we are finding a lot of arrhythmias that would have previously remained unidentified. If episodes of NSVT are being found on home monitoring devices, the patient should receive a formal monitor to confirm NSVT. The formal monitor should be a Holter monitor that is able to quantify the burden and morphologies of PVCs. The patient should also receive an echocardiogram. Presuming the echocardiogram is normal and the burden of NSVT is low, nothing further might be required. An abnormal echocardiogram, particularly low ejection fraction, should prompt an evaluation as to causes and risk for sudden cardiac arrest. If the echocardiogram is normal but the patient has a high burden of PVCs or multifocal PVCs, an MRI may...
