Laboratory Findings
- Hypocalcemia, hypokalemia, and hypomagnesemia make patients vulnerable to monomorphic VT or torsade de pointes.
- Diuretic usage can lead to hypokalemia which can provoke ventricular tachycardia.
- Cardiac troponin I and cardiac troponin T levels along with CK-MB and LDH can help access myocardial ischemia or infarction.
- Digoxin and tricyclic antidepressant blood levels should be ordered.
- Sometimes recreational drugs like cocaine, can result in ventricular tachycardia so a toxicology screen should also be obtained.
