Systems and method for assessing a likelihood of a patient having a heart to experience a cardiac arrhythmia. A sensor is configured to detect a premature ventricular contraction of the heart, the premature ventricular contraction being premature relative to a rate of ventricular contractions during a period preceding the premature ventricular contraction. A processor is configured to determine a dispersion of a predetermined number of repolarizations of the heart of the patient occurring following the premature ventricular contraction of the heart if a compensatory pause is detected in conjunction with the premature ventricular contraction, then determine the likelihood of the patient experiencing the cardiac arrhythmia based, at least in part, on the dispersion of the plurality of repolarizations of the heart of the patient. |
