Taquicardia sinusal y taquicardia sinusal inapropiada

Abstract

IntroductionSinus tachycardia is one of the most frequently encountered arrhythmias in clinical practice and its identification should place us on the trail of an intercurrent process in our patient, which may be benign (anxiety or painful) or life threatening (sepsis Severe or pulmonary thromboembolism, among others). On the other hand, inappropriate sinus tachycardia does not respond to a normal pathophysiological mechanism. DiagnosisThe diagnosis will be based on a correct differential electrocardiographic diagnosis to differentiate it from other arrhythmias, fundamentally the atrial tachycardia and in a complete study that allows us to identify the cause that causes it, or to rule out its existence. A 24-hour holter-ECG may be useful in the diagnosis of inappropriate sinus tachycardia. ManagementIn the case of appropriate sinus tachycardia, the treatment will correspond to the underlying pathology that has triggered the arrhythmia. For the inappropriate sinus tachycardia, the braking agents, particularly ivabradine, are useful because of their selective effect on the sinus node and its excellent hemodynamic profile, which makes them very safe and well tolerated drugs.
