An amateur radio console will not impact a heart device as long as proper distance from the transmitting antenna is maintained. That distance will depend on power transmission:

3 watts or less = 6 in (15 cm)
3-15 watts = 12 in (30 cm)
15-30 watts = 24 in (60 cm)
30-50 watts = 3 ft (1 m)
50-125 watts = 6 ft (2 m)
125-250 watts = 9 ft (3 m)
250-500 watts = 12 ft (4 m)
500-1,000 watts = 20 ft (6 m)
1,000-2,000 watts = 30 ft (10 m)
