Cardiac arrest is due to electrical dysfunction of heart.... Tia is something related to the decreased oxygen supply to myocardial muscles
Isn't Tia related to decreased blood supply to brain?? How do you help someone who has a tia suddenly??
Not a doctor.. a TIA is a Transient Ischemic Attack. i.e., a mini stroke. Ultrasound, CT, and CTA of the head are used to diagnose. Treatment consists of blood thinners or thrombolytics.
