The Lead Episode 89: Vasovagal Responses to Human Monomorphic Ventricular Tachycardia Hemodynamic Implications From Sinus Rate Analysis-The Lead Episode 89 Speaker Information

The Lead Episode 89 Speaker Information

Pdf Summary

The discussion, hosted by Dr. Jason T. Jacobson from Westchester Medical Center, focuses on the study of vasovagal responses to human monomorphic ventricular tachycardia and their hemodynamic implications, as analyzed through sinus rate. The article, authored by a team including Dr. Margarida Pujol-Lopez and others, was published in the Journal of the American College of Cardiology. The session includes contributions from Dr. Melissa R. Robinson of Providence Heart Institute and Dr. Sei Iwai, also from Westchester Medical Center.<br /><br />The researchers examine how vasovagal responses, reflex actions of the nervous system that can cause fainting or decreases in heart rate and blood pressure, affect individuals experiencing monomorphic ventricular tachycardia, a type of consistent rhythm disturbance in the heart's ventricles. Understanding the sinus rate, which measures the heart's rhythm originating from the sinus node, could shed light on the hemodynamic consequences of these responses. Hemodynamics involve the flow and regulation of blood in the cardiovascular system, crucial for maintaining sufficient blood circulation.<br /><br />Disclosures indicate that Dr. Sei Iwai and Dr. Jason T. Jacobson have received honoraria and consulting fees from several medical companies and have affiliations with advisory committees. Dr. Jacobson also has a stake in a privately held company, while Dr. Iwai's honoraria involve speaking and consulting engagements with two pharmaceutical firms. These disclosures are vital for understanding any potential conflicts of interest in the research presentation.<br /><br />This discussion aims to provide valuable insights into the physiological responses during monomorphic ventricular tachycardia and offers an understanding of how to potentially manage these events in clinical settings through a detailed analysis of sinus rate data.
