| Symptoms are often mixed with those of the underlying illness but may include cardiac dysrhythmias, confusion, convulsions, muscle cramp and tetany. |
| The role of digoxin in the treatment of a failing heart without dysrhythmias is unclear. |
| Other reasons for sudden death include cardiac dysrhythmias related to hypoxia, hyperinflation leading to air trapping, and tension pneumothorax. |
| Uncorrected hypokalaemia can have many adverse effects including cardiac dysrhythmias and muscle weakness. |
| Post-MI patients had statistically significant increases in heart failure and dysrhythmias. |
