Claim Text:
1. A method, comprising: receiving respective electrocardiograph (ECG) signals from body-surface electrodes at respective locations in proximity to a heart of a subject; processing the ECG signals to generate respective signal parameters thereof characteristic of positions of the body-surface electrodes with respect to the heart by finding baselines for the signals; generating the respective signal parameters by determining whether differences between maximum deviations from the baselines are positive or negative; enumerating as a first number the body-surface electrodes having a positive difference, and enumerating as a second number the body-surface electrodes having a negative difference, wherein achieving the specified geometrical relationship comprises the first and the second numbers differing by no more than a preset number; and adjusting the respective locations so as to achieve a specified geometrical relationship between the body-surface electrodes and the heart in response to the respective signal parameters.
