Overview

There aren't any specific findings associated with pulseless ventricular tachycardia. However, investigations should be conducted to find the underlying etiology of the arrhythmia.

Laboratory Findings

  • There aren't any specific diagnostic laboratory findings associated with pulseless ventricular tachycardia.
  • To find the underlying etiology of the arrhythmic event, the following investigations should be conducted;
    • Serial cardiac enzymes; these can help assess myocardial ischemia or infarction. They include;
  1. Troponin I and Troponin T
  2. Creatinine-kinase MB
    • Serum electrolytes;[1][2] measuring electrolyte levels are important as imbalances in certain electrolytes predispose patients to torsade the pointes, a common cause of pulseless ventricular tachycardia. Important electrolytes to measure include;
  1. Calcium
  2. Potassium
  3. Phosphate
  4. Magnesium
    • A toxicology screen should be obtained to measure levels of therapeutic and illicit drugs (cocaine) as they can result in ventricular tachycardia.
