Background: Only a few algorithms for predicting the site of origin of focal atrial tachycardia (AT) have been reported. We aimed to develop a new and more effective algorithm. Methods: Surface ...

Tachycardia describes when the heart beats faster than normal. Sinus rhythm with tachycardia occurs when the sinus node fires electrical impulses abnormally quickly. Inappropriate sinus tachycardia ...

Sinus tachycardia is the most common and often neglected rhythm disturbance encountered in clinical practice. Whether appropriate or not, it is often associated with troublesome symptoms, and ...

Most wide QRS complex tachycardias (WCTs) are ventricular or supraventricular in origin, but to differentiate between the two can present a diagnostic challenge. To develop and test an algorithm that ...

What Is Inappropriate Sinus Tachycardia? Sinus tachycardia is when your body sends out electrical signals to make your heart beat faster. Hard exercise, anxiety, certain drugs, or a fever can spark it ...

Sinus tachycardia is a heart rate that is faster than normal, and it can be triggered by exercise, stress, or anxiety. However, it may also indicate an underlying health problem. Symptoms of sinus ...

The retrospective study population included 61 patients (29 men) with a mean age of 42 ± 5 years. Echocardiography showed normal LA (33.4 ± 1.5 mm) and normal ejection fraction (63.1 ± 2.3%). Two ...
