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;[1] these can help assess myocardial ischemia or infarction. They include;
- Troponin I and Troponin T
- Creatinine-kinase MB
- Serum electrolytes;[2][3] 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
- Potassium
- Phosphate
- Magnesium
- A toxicology screen should be obtained to measure levels of therapeutic and illicit drugs (cocaine) as they can result in ventricular tachycardia.
