Inappropriate Sinus Tachycardia
Cardiology in Review, 2012Inappropriate sinus tachycardia (IST) is an uncommon form of arrhythmia characterized by an increased heart rate that is out of proportion to a normal physiologic demand. The etiology of IST remains ill-defined and controversial. Clinical presentation of IST is highly variable, from isolated to sustained palpitations, and can cause deterioration in one'

Sinus node re-entry and sinus node tachycardia
American Heart Journal, 1975Five patients are reported with SN echoes which could be produced by the technique of APD. The RA was paced at the basic rate and the SEI was measured repeatedly. SN echoes were diagnosed on the basis of: (1) A1A3 interval shorter than the SEI; (2) upright P-waves in Leads II and III; (3) activation of high RA preceding the activation of low RA; (4 ...

Sinus tachycardia masquerading as ventricular tachycardia.
The Tokai journal of experimental and clinical medicine, 1991We describe here a 87-year-old male who came to the emergency room with the chief complaints of dyspnea and chest pain. His electrocardiogram showed a wide QRS tachycardia with a heart rate of 140 beats/min, a left bundle branch block pattern and low voltage in leads I, aVL, V5 and V6.

Various tachycardias presenting with positive P waves in the standard leads are described in this article. Sinus tachycardia may occur as a normal adaptation reaction to the environment or in the setting of autonomic dysregulation. It may also be mimicked by various arrhythmias which share the earliest depolarisation in the sinus node area. The authors

[Inappropriate sinus tachycardia].
Deutsche medizinische Wochenschrift (1946), 2015Inappropriate sinus tachycardia is characterized by an unexplained increase of the resting sinus rate (> 100 bpm) with excess increase in response to moderate activity (mean heart rate > 90 bpm/24 h). Affected patients may suffer from heart race, palpitations, fatigue, weakness and dizziness.

[Sinus tachycardia in pregnancy].
Ugeskrift for laeger, 2019Sinus tachycardia may have a definite aetiology, but in the remaining cases inappropriate sinus tachycardia (IST) may be considered. IST is primarily treated in order to improve symptoms. During pregnancy, tachycardia-induced cardiomyopathy is rare; however, it needs urgent attention and treatment due to the risk of fast progression.
