Diagnosis of paroxysmal tachycardia
The disease may already be suspected during the initial examination by a physician. In particular, paroxysms are defined as attacks that can disturb the patient or proceed asymptomatic. The patient is referred to the ECG, where the following signs of paroxysmal tachycardia are defined: the fast rhythm of more than 150 beats per minute (in adults), develops suddenly, looks like extrasystoles, which follow one after another. In some cases, paroxysms can not be fixed on a standard ECG, then do daily monitoring, which may take several days or more if necessary. Bicycle ergometry, ultrasound and heart rate tests help determine the pathology.
