What is the diagnosis and treatment algorithm for taquiarritmias?

The diagnosis of taquiarritmias is based on the evaluation of hemodynamic tolerance and a twelve-lead ECG.
The treatment of taquiarritmias depends on the differentiation between ventricular and supraventricular tachycardia.
In case of poor hemodynamic tolerance, urgent cardioversion or external defibrillation may be necessary.
The presence of a previous myocardial infarction or acute myocardial ischemia should be ruled out or confirmed in the initial evaluation.
