Michael experiences a heart murmur, so he consults with his GP, Dr Kee. Dr Kee tells Michael not to worry and decides not to send Michael for further tests. Shortly thereafter, Michael suffers a cardiac arrest and as a result is brain damaged. Michael now intends to claim damages for negligence, arguing that Dr Kee should have taken a possible cardiac problem into account when the heart murmur was detected and arranged an ECG and referral to a cardiologist. Advise Michael whether Dr Kee breached duty of care.
