Why the study?
Does intravenous atropine sulfate alter sympathetic and vagal activities differently in heart failure patients compared to healthy volunteers?
Does intravenous atropine sulfate alter sympathetic and vagal activities differently in heart failure patients compared to healthy volunteers?
Heart failure patients exhibit reciprocal supranormal sympathetic and subnormal parasympathetic outflows that are unresponsive to low-dose atropine, suggesting central nervous system autonomic abnormalities.
Alerts to central autonomic dysregulation in HF; hypothesis-generating for vagal-targeted therapies.
