A stroke is an acute medical emergency that is life-threatening and occurs when part of the brain is starved of oxygen due to either a blood clot or a bleed (hemorrhage).

Atrial Fibrillation (AF) is the term used when your heart beats in an irregular pattern and is often beating too fast. This may first be noticed as palpitations and can be diagnosed on an ECG. Some blood pressure meters can also help detect irregular heartbeats.

Acute coronary syndromes (ACS) refers to a group of conditions linked to chest pain, including unstable angina and myocardial infarction (heart attack).
