Coronary Flow During Rapid Heart Rates
Sponsor: Imperial College London
Summary
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.

Pressure and flow measurement during simulated VT
Participants undergoing coronary angiography will have measurements of blood pressure, coronary pressure and coronary flow during simulated VT. VT will be simulated using pacing at a range of heart rates.
