“…For each subject, V O 2max was estimated by a maximal treadmill test using the Bruce protocol (Bruce et al 1973). Atrial automaticity and atrioventricular conduction were evaluated by transesophageal atrial stimulation (Santini et al 1990), and 24-h heart rate variability was studied by the time-domain index square root of the mean of the sum of squares of dierences between adjacent RR intervals (rMSSD). The protocol was approved by the hospital Research Committee, and each individual gave their written, informed consent to participate.…”

“…However, little is known about the sinoatrial automatism and atrioventricular conduction of trained individuals who present a normal resting electrocardiogram. We used transesophageal atrial stimulation (Santini et al 1990), a minimally invasive technique, to evaluate aerobically trained athletes and sedentary individuals with normal resting electrocardiograms, to test the hypothesis that parasympathetic tone, as detected by heart rate variability, could be associated with changes in sinoatrial automatism and atrioventricular conduction.…”

Little is known about the sinoatrial automatism and atrioventricular conduction of trained individuals who present a normal resting electrocardiogram. We used transesophageal atrial stimulation, a minimally invasive technique, to evaluate aerobically trained athletes (n = 10) and sedentary individuals (n = 10) with normal resting electrocardiograms, to test the hypothesis that parasympathetic tone, as detected by heart rate variability, could be associated with changes in sinoatrial automatism and atrioventricular conduction. Corrected sinus node recovery time tended to be longer in athletes than in sedentary individuals, but this difference did not reach statistical significance. The Wenckebach point occurred at a lower rate in athletes than in the controls. Over a 24-h period of measurement, the mean RR interval was longer in the athletes than in the sedentary individuals. The mean square root of successive differences (rMSSD) tended to be higher in athletes than in controls, but this difference did not reach statistical significance. There was a moderate correlation (r = 0.48, P < 0.05) between the index of atrioventricular conduction, the rate at the Wenckebach point, and the logarithmically transformed rMSSD. Thus, as a corollary to its effects on the sinus node, where increased parasympathetic tone, decreased sympathetic tone, and non-autonomic components may contribute to sinus bradycardia, it is possible that athletic training may also induce intrinsic adaptations in the conduction system, which could contribute to the higher prevalence of atrioventricular conduction abnormalities observed in athletes.

“…5 Transesophageal pacing has been used successfully in human patients for decades and can provide rapid chronotropic support and maintains atrioventricular synchrony in patients without clinically significant atrioventricular block. 6 Most importantly, there are few complications associated with TAP reported in human medicine. 6 In human patients with anesthesia related bradycardias, TAP has been shown to provide chronotropic support more rapidly and without excessive tachycardia when compared to treatment with atropine.…”
