Jenny Butler works in acute General Medicine at Christchurch Hospital.
She was always interested in syncope, with people admitted for investigation of collapse being a daily occurrence in General Medicine.
She became more interested in autonomic medicine whilst doing an advanced training project on sympathetic nerve function (under the supervision of Dr Jardine) in 2008. Dr Butler has subsequently continued to work in the ‘funny turns clinic’ one afternoon per week.
Particular areas of interest include tilt testing, diagnosis of ‘funny turns’ (is it a heart problem? low blood pressure? seizure? functional? something else?), management of postural hypotension and vasovagal syncope, autonomic neuropathy, and POTS (postural tachycardia syndrome).
She is also interested in quality, teaching, and communication in healthcare. She works 0.7FTE at the DHB
