Relationship between QRS duration and left ventricular mass and volume in patients at high cardiovascular risk

OBJECTIVE: Longer QRS duration on the ECG is associated with increased cardiovascular (CV) mortality. To evaluate potential mechanisms, we examined in this study the relationship between QRS duration and left ventricular (LV) mass and LV end systolic and end diastolic volume in patients with known CV disease or high-risk diabetes. METHODS: In a substudy of the ONTARGET/TRANSCEND (Ongoing Telmisartan Alone and in Combination with Ramipril Global …
