Bundle branch block patterns, age, renal dysfunction, and heart failure mortality

The determinants of bundle block patterns and their relationship to mortality in heart failure patients is not completely understood. We evaluated 2907 consecutive patients admitted to an intensive care unit with decompensated heart failure over 8 years. Clinical and echocardiographic factors were a...

Description
Summary:The determinants of bundle block patterns and their relationship to mortality in heart failure patients is not completely understood. We evaluated 2907 consecutive patients admitted to an intensive care unit with decompensated heart failure over 8 years. Clinical and echocardiographic factors were analyzed using multivariate techniques. All-cause mortality was available on greater than 99.0% of patients at a median of 23 months after discharge. Right and left bundle branch blocks occurred in 211 (7.3%) and 386 (13.2%), p
