Electrocardiogram recording by telephone in antiarrhythmic drug trials.
The purpose of this study was to evaluate ECG recording by telephone as a research tool for documenting the cardiac rhythm during symptoms of paroxysmal atrial tachycardia. Eleven patients were enrolled in the study during the first year. They transmitted 34 rhythm strips during symptoms, 17 of which showed paroxysmal atrial tachycardia; only one of the 34 was uninterpretable. Three patients thought they were having paroxysmal atrial tachycardia when their rhythm strips showed that they were having sinus tachycardia. Patient compliance and satisfaction with our follow-up system were high. Our study supports the use of ECG recording by telephone as an excellent tool to document arrhythmias in patients enrolled in clinical trials.
