She had irregular heart beats since utero, but went undiagnosed for 2 years. At 3, she had a
pacemaker put in for a 2nd degree heart block. Now, at 7 years old and only 38lbs, she is having bouts of 180-200bpm, at resting rate. Pacemaker has been recording these bouts for 4 years now. Nurse explained to me that her pacemaker is constantly kicking in when it shouldn't be (70-100bpm), even though it's set at 60bpm.
