Key result
Patients with acute exacerbation of COPD and ventricular tachycardia had significantly lower heart rate deceleration capacity (4.13 vs 5.62 ms, p=0.036) compared to those without ventricular tachycardia.
Why the study?
Does the presence of ventricular tachycardia correlate with altered cardiac autonomic function in patients with acute exacerbation of chronic obstructive pulmonary disease?
Observational (n=70)
No

Absolute Event Rate: 4.13% vs 5.62%
p-value: p=0.036
Patients with acute exacerbation of COPD and ventricular tachycardia exhibit significant impairment of cardiac autonomic function, characterized by decreased deceleration capacity and increased acceleration capacity, which may indicate an increased risk of sudden death.
No takes yet. Share an insight, caveat, or question.
Altered DC/AC may flag VT risk in AECOPD; hypothesis-generating for autonomic monitoring, prospective validation required.
Wang et al. (2016) conducted an observational in Acute exacerbation of chronic obstructive pulmonary disease (n=70). Ventricular tachycardia vs. Absence of ventricular tachycardia was evaluated on Deceleration capacity (DC) of heart rate (p=0.036). Patients with acute exacerbation of COPD and ventricular tachycardia had significantly lower heart rate deceleration capacity (4.13 vs 5.62 ms, p=0.036) compared to those without ventricular tachycardia.
