Q.1 If you think someone is having a heart attack (usually a feeling of extreme pressure or pain in the chest, neck or arms associated with being generally unwell), the best way to get treatment to them rapidly is by calling a 999 ambulance right away. Calling the Doctors surgery will waste valuable minutes of time while you are put through and dealt with. Someone having a heart attack needs to be got into the nearest large hospital as rapidly as possible.
Q.2 The pulse at the wrist is called the Radial pulse. ( The pulse is caused by the flow of blood through the Radial artery.).
Q.3 All muscles in the body need to be supplied with oxygen in order to work. The oxygen is delivered to the muscles and other parts of the body by the blood. The muscle in the heart needs a supply of blood to work too, just like all the muscles everywhere else. The heart muscle gets its supply of blood through several little arteries that run across the surface of the heart called the coronary arteries. As we all get older, these arteries become clogged up with fatty deposits. This clogging happens much faster if you smoke or eat a lot of fat in your diet. When the fatty deposit gets so big it blocks off the artery completely, no blood can get through to the heart muscle. (Often a clot of blood forms on the fat that suddenly blocks the flow). The area of the heart muscle that the artery takes blood to stops working when no blood reaches it and the heart thus becomes weaker. When this happens it is called a heart attack. If the area affected is very large o affects the way electricity flows through the heart, it may stop beating, but this does not happen in every heart attack.
Q.4 A Tachycardia is the medical term for when the heart beats too fast
Q.5 The two parts of a blood pressure reading are called systolic and diastolic. The higher (systolic) reading is the pressure in the system when the heart is pushing the blood out, the lower reading is the pressure when the heart is relaxing and filling up with the next load of blood to push out.
Q.6 There are four chambers in the heart.Two, the Atria, recieve the blood from the body, the other two, the VEntricles, pump it out again.
