Common medical conditions explained: high blood pressure

The condition High blood pressure is also called ‘hypertension’. Blood pressure is recorded in two numbers – the high number is called systolic and this is the pressure when the heart has just pumped. The low number is called diastolic and this is the pressure when the heart is at rest. The pressure is measured in ‘millimetres of mercury’ or mmHg. Ideal blood pressure is between 90/60mmHg and 120/80mmHg. High blood pressure is considered to be anything above 140/90mmHg.
