Some Useful Information about Blood Pressure

What is Blood Pressure?

Blood pressure is a measure of the force of blood flowing against the walls of the arteries. 
Arterial blood pressure is constantly changing during the course of the heart’s cycle. 
The highest pressure in the cycle is called the 

Systolic Blood Pressure

; the lowest is the 

Diastolic Blood Pressure

. Both pressures, the 

Systolic

 and 

Diastolic

, are necessary to enable 

a physician to evaluate the status of a patient’s blood pressure.

What is Arrhythmia?

Arrhythmia is a condition where the heartbeat rhythm is abnormal due to flaws in the bio-
electrical system that drives the heartbeat. Typical symptoms are skipped heartbeats, 
premature contraction, an abnormally rapid (tachycardia) or slow (bradycardia) pulse.

Why is it a Good Thing to measure Blood Pressure at Home?

Many factors such as physical activity, 
anxiety, or the time of day, can influence 
your blood pressure. A single 
measurement may not be sufficient for an 
accurate diagnosis. Thus it is best to try 
and measure your blood pressure at the 
same time each day, to get an accurate 
indication of any changes in blood 
pressure. Blood pressure is typically low in 
the morning and increases from afternoon 
to evening. It is lower in the summer and higher in the winter.
