Overview
Laboratory findings predicting sudden cardiac arrest and ventricular tachycardia include elevated level of Natriuretic peptides—B-type (BNP) or N-terminal pro-BNP as the marker of myocardial stress and fibrosis in heart failure disease, highly sensitive troponin T indicating cardiomyocyte injury, screening about hypokalemia, hypomagnesemia and also toxic level of digoxin, cocaine, tricyclic antidepressant.
Laboratory Findings
Common laboratory findings predicting sudden cardiac arrest and ventricular tachycardia include:
- Elevated level of Natriuretic peptides—B-type (BNP) or N-terminal pro-BNP as the marker of myocardial stress and fibrosis in heart failure disease predicting SCD[1]
- Highly sensitive troponin T indicating cardiomyocyte injury[2]
- Electrolytes abnormality such as hypokalemia, hypomagnesemia relation QT prolongation and torsades de pointes[3]
- Tricyclic antidepressant poisoning associated with QT prolongation [5]
- Cocaine toxicology screening[6]
| Laboratory Pearls for Ventricular Tachycardia | |
|---|---|
| Electrolytes | Hypokalemia and hypomagnesemia frequently associated with torsades de pointes |
| Troponin I | Elevated in myocardial infarction |
| Creatine-kinase MB | Elevated in myocardial infarction |
