[The differential diagnosis of the main forms of paroxysmal tachycardias and tachyarrhythmias].

A study is presented of 150 in-patients with paroxysmal tachycardias and tachyarrhythmias. Urgent management was carried out using a diagnostic algorithm designed by the authors that helped to establish early diagnosis using clinical adequate rational methods. Identification of clinico-pathogenetic form was realized in 95% of patients. Invasive examination was carried out in dubious cases. Transesophageal examination of the heart is of high value in emergency cardiology.
