[Development of arrhythmia in patients after heart surgery in relation to the length of the Q-T interval].
To predict intra- and postoperative ventricular arrhythmias, the length of Q-T interval was determined in 29 patients after cardiosurgical interventions made under artificial circulation by using ECG monitoring. The occurrence of ventricular arrhythmias were found to be related to a Q-T interval index of more than 20% of the normal value. The application of simple computer systems allows the Q-T interval to be monitored on line, identifying patients at a high risk for arrhythmias and using an adequate antiarrhythmic therapy.
