1.   Cardiac arrhythmias rarely result from levodopa administration to patients who have a predisposition related to underlying cardiac disease.

2.   More complicated models for the simulation of cardiac arrhythmias are available for nurses specialising in intensive care work.

3.   One should be aware of the induction of cardiac arrhythmias in older people or those with such a predisposition.

4.   Potential lethal cardiac arrhythmias and convulsions are recognised complications of both iatrogenic and self inflicted overdoses.

5.   Put simply, cardiac arrhythmia is an irregular heartbeat.

6.   While toxic concentrations of these drugs often lead to cardiac arrhythmias, low concentrations have been found to have antiarrhythmic activity.

7.   There was no significant relation between cardiac arrhythmias or ST segment change and age, sex, shortness of breath, or cardiac history.

8.   In addition, there was no relation between cardiac arrhythmias or ST segment change and age, sex, shortness of breath or cardiac history.

9.   It was therefore not possible to predict, on the basis of patient characteristics, those who would develop cardiac arrhythmias.
