Chair test. The functional chair test was performed at the same time of day, in a comfortable room with an ambient temperature of 25 °C. Both patients were asked to rise from a chair after a 5 min rest and perform three turns around the chair as quickly as they could (T1). The performance was repeated 5 min later (T2) and once again without any rest (T3), in order to evaluate the warm-up phenomenon or paradoxical worsening. The time spent to perform the exercise was measured with a stopwatch. The test was performed when the patient was taking mexiletine, then 12 (test #1) and 21 (test #2) months after the introduction of flecainide. The test showed a remarkable improvement in both mother and son with flecainide treatment
