Abstract:
1. A method for evaluating ventricular pacing sites for cardiac resynchronization therapy (CRT) comprising: applying ventricular pacing at a first pacing site; obtaining electrocardiogram (ECG) data representing the first pacing site from a set of electrodes as an ECG lead; isolating a QRS complex from the ECG lead; extracting a predictor value representing a frequency component of a QRS complex within the ECG lead, the predictor value comprising one of a maximum power within a frequency band of interest, a minimum power within the frequency band of interest, frequencies having a maximum power, frequencies having a minimum power, a median frequency, a total power within the frequency band of interest, intercept values, a slope within the frequency band of interest, and a mid-band fit for the frequency band of interest; determining a fitness parameter for the first pacing site, representing the likelihood that the CRT will be successful at the first pacing site, from at least the extracted predictor value; and displaying the fitness parameter to a user at an associated display.
