The main symptom of coronary heart disease is angina which can be caused by insufficient oxygen reaching the heart muscle because of reduced blood flow; this can lead to mild, uncomfortable pain within the centre of your chest which can relate to that of indigestion, however no severe damage is caused by an angina attack. The pain from this type of attack can spread to other parts of the body including the arms, neck, jaws, back or stomach. Symptoms usually don’t last longer than 10 minutes and are triggered by physical activity or stress.

An arrhythmia is a problem with the rate or rhythm of the heartbeat. When you have an arrhythmia, you may notice that your heart is skipping beats or beating too fast. Arrhythmias can also be described as having heartbeat being unusually rapid and forceful heartbeat called palpitations. Some arrhythmias can cause your heart to suddenly stop beating. This condition is called (SCA). SCA usually causes death if it's not treated within minutes.
