“…Ventricular arrhythmias related to exercise have been shown to appear more commonly during the recovery period than during the exercise (Gooch et al 1970). Because enhanced vagal nerve activity may suppress the occurrence of arrhythmias, the enhancement of postexercise vagal nerve reactivation with training could reduce the incidence of arrhythmias leading to fatalities.…”

We studied the effects of aerobic exercise training and detraining in humans on post-exercise vagal reactivation. Ten healthy untrained men trained for 8 weeks using a cycle ergometer [70% of initial maximal oxygen uptake (VO2max) for 1 h, 3-4 days.week-1] and then did not exercise for the next 4 weeks. Post-exercise vagal reactivation was evaluated as the time constant of the beat-by-beat decrease in heart rate during the 30 s (t30) immediately following 4 min exercise at 80% of ventilatory threshold (VT). The VO2max and the oxygen uptake at VT had significantly increased after the 8 weeks training programme (P < 0.0001, P < 0.001, respectively). The t30 had shortened after training, and values after 4 weeks and 8 weeks of training were significantly shorter than the initial t30 (P < 0.05, P < 0.01, respectively). The change in the t30 after 8 weeks of training closely and inversely correlated with the initial t30 (r = -0.965, P < 0.0001). The reduced t30 was prolonged significantly after 2 weeks of detraining, and had returned almost to the baseline level after a further 2 weeks of detraining. These results suggest that aerobic exercise training of moderate intensity accelerates post-exercise vagal reactivation, but that the accelerated function regresses within a few weeks of detraining.

“…Thus because of this abundance of blood supply to the AV node, ischemia-induced AV block is rare and appears to require either extensive ischemia or synergistic cofactors such as augmented vagal tone. This may explain the rarity of AV block in the context of exercise induced ischemia [8].…”

“…G o o c h and M c C o n n e l l [8] reported 23.3% reproducibility of ar rhythmias using a submaximal treadmill exercise test. They excluded ar rhythmias having less than three consecutive beats, isolated or paired premature beats, sinus arrhythmias and wandering atrial pacemaker.…”

The yield and reproducibility of various methods of ventricular premature beat (VPB) detection are examined in otherwise healthy middle-aged men first found to have VPB in a 2-min lead I ECG rhythm strip. With a combination of an isometric and treadmill exercise test, VPB were repeatedly detected in 83%. Test-retest reliability in classifying the subjects by frequency of VPB was 67%. The reliability of detecting complex VPB was 47% for multiform VPB, 35% for pairs of VPB, 17% for runs and 36% for VPB showing the R-on-T phenomenon. These data suggest that simple and complex VPB detected by the described methods among normal men are poorly reproducible in the individual. Taking the VPB reproducibility for the group as a whole, the proportion of subjects having different frequency or kinds of ectopic beats is reasonably stable for the different test occasions.
