Paroxysmal tachycardia encompasses various heart rhythm disorders that cause rapid heart rates. Its episodic occurrence makes it difficult to identify and measure its prevalence and trends in the population. Additionally, there is limited data on disparities and trends in mortality due to paroxysmal tachycardia, which is essential for assessing current medical approaches and identifying at-risk populations. Trends in AAMRs were analyzed using the Joinpoint Regression Program to identify significant changes and inflection points in mortality trends throughout the study period.
Between and , , deaths were reported in patients with paroxysmal tachycardia. Overall, AAMR decreased from 4. Men had consistently higher AAMRs than women 4. Nonmetropolitan areas had higher AAMRs than metropolitan areas 3. Our analysis showed a significant decrease in mortality from paroxysmal tachycardia since , although there has been a slight increase in recent years. These findings call for immediate public health actions to curb the rising trends and reduce potential disparities.

Competing interests: The authors have declared that no competing interests exist. Paroxysmal tachycardia, also known as episodic tachycardia, encompasses a subset of abnormal heart rhythms, including re-entry ventricular arrhythmia, supraventricular tachycardia SVT , and ventricular tachycardia VT. Mismanagement of any of these conditions can have lethal consequences. Among them, re-entrant arrhythmia has been associated with relatively low mortality rates.
However, it still has been found to pose long-term health risks, including stroke and thromboembolism in specific subtypes [ 1 β 3 ]. Therefore, due to its association with SHD, it is considered the most common arrhythmia in children, affecting around 1 in otherwise healthy children [ 2 , 3 ].
