Biotelemetry transmitters were surgically implanted in the abdominal cavity of 12 mature swamp rabbits, Sylvilagus aquaticus, to monitor the heart-rate response to forced and voluntary diving. Atropine and propranolol were used to investigate autonomic control of heart rate. Each untreated rabbit showed a marked (- 79%) bradycardia when forcefully submerged for 10 s. Mean heart-rate values during predive, dive, and recovery were 213 ± 12.6, 44 ± 7.5, and 206 ± 14.9 beats/min (X̅ ± SE… Expand
