Heart Failure
About this trial
This is an interventional treatment trial for Heart Failure focused on measuring cardiac resynchronization therapy, left ventricular Lead, Heart Failure
Eligibility Criteria
Inclusion Criteria: QRS > 130 ms (The QRS interval is a measurement of how the electrical signal involved in a heart beat travels, or is conducted, through the ventricles. A wide QRS (more than 120) suggests that there is a conduction problem, or block, in the ventricles.) Left Ventricular Ejection Fraction (EF) < 35% (Ejection Fraction is a measurement of how well the left ventricle pumps blood out to the rest of the body. The higher the EF the more blood the ventricle is pumping.) Subject has moderate to severe heart failure despite medications Exclusion Criteria: Subjects with a previous lead in the left ventricle or previous implant attempt within 30 days of implant or ongoing complications from a previous unsuccessful attempt Subjects with chest pain or who have had a heart attack within the past month before enrollment in the study Subjects that have had certain surgeries on their heart within the past three months Subjects with chronic (permanent) fast heart beats in the upper chambers of the heart (atrial arrhythmias)
