Overview

The diagnosis of pulseless ventricular tachycardia is based on ECG and physical examination findings. An ECG should be the initial study, and other investigations may be carried out afterwards to determine the underlying aetiology.

Diagnostic Study of Choice

Study of choice

  • An ECG should be the initial study,[1] and other investigations may be carried out afterward to determine the underlying etiology.[2]
  • In order to evaluate left and right ventricular function in patients with ventricular arrhythmias, echocardiography should be performed.[3]
  • If echocardiography fails to determine ventricular function, MRI, cardiac CT scanning, or radionuclide angiography can be useful assessments of structural heart changes.
