Coronary Flow During Rapid Heart Rates
Coronary Epicardial and Microcirculatory Determinants of Ventricular Tachycardia Tolerability
Source: ClinicalTrials.gov · Last updated 27 Mar 2026
Brief summary (registry, in English)
The goal of this observational study is to learn about the factors which determine how well ventricular tachycardia (VT) is tolerated. The main questions it aims to answer are: 1. What impact does coronary artery disease have on the ability for a patient to tolerate VT? 2. Does treatment of coronary artery disease with stents improve the tolerability of VT? Participants who are undergoing a clinically indicated coronary angiogram or coronary angioplasty procedure will have measurements of blood pressure, coronary pressure and coronary flow made during pacing at a range of heart rates.
