Physiological pacing improves symptoms and increases exercise capacity in the elderly patient . We evaluated the benefits of physiological pacing in the elderly by recruiting 13 subjects > 75 years of age , already fitted with a physiological pacing system . All had been paced for complete or Mobitz II heart block . Double blind cross over study was performed comparing exercise capacity , measuring distance walked on a 6-min walking test and time taken to climb two flights of stairs ; and symptoms , evaluated by an activity of daily living questionnaire , in atrioventricular synchronous and ventricular pacing . Mean distance walked was significantly higher in atrioventricular synchronous than in ventricular pacing ( 360 +/- 65 m vs. 327 +/- 69 m ; P < 0.01 ) . No significant difference was found in the ability to climb stairs but there was a marked improvement in the symptomatic questionnaire score , 19 +/- 5 in physiological pacing increasing to 28 +/- 10 with ventricular . Physiological pacing in the elderly produces an increase in exercise tolerance and improves symptoms ; therefore , age alone should not be a contraindication to a physiological system .
