| Acutely, it depresses the central nervous system and can also precipitate cardiac arrhythmia. |
| Orthodromic tachycardia is the most common arrhythmia in patients with Wolff-Parkinson-White syndrome. |
| Despite use of continuous ECG recording, there were no signs of arrhythmia. |
| In normal subjects who rebreathed carbon dioxide, QT dispersion was increased, which could signal a risk of arrhythmia. |
| Because cases of ventricular arrhythmia and cardiac arrest may go undiagnosed, we also examined deaths from all causes. |
| Ten mice with the defect thrived after receiving the drug and never developed an arrhythmia, while eight out of nine untreated animals died. |
