   Blood flows through your heart, lungs and body in a series of steps. After delivering oxygen and nutrients to all your organs and tissues, your blood enters your heart and flows to your lungs to gain oxygen and get rid of waste. It then flows back to your heart, which pumps the refreshed blood out through your aorta to nourish your body again.

   • Arrhythmia (irregular heartbeat) symptoms. It is normal for a person to have heart palpitations or a fast or slow heart rate according to their activity and stress levels at the time, but speak to your doctor if the symptoms are ongoing or if you are concerned.
   • Atherosclerosis. Atherosclerosis usually does not cause symptoms until it is at an advanced stage, when the narrowing of arteries becomes so severe that blood flow to the organs and tissues is interrupted or blocked, and CVD has developed.
   • Atrial fibrillation. Atrial fibrillation (AF) may not cause any symptoms, or the symptoms may only occur some of the time. AF can remain undetected for long periods of time, which is why it is so important to screen for AF.
   • Cardiac arrest. Cardiac arrest usually happens suddenly and without warning. The risk of cardiac arrest increases with age, and men are at higher risk than women.

   How does a heart problem affect blood flow?

   • It also describes problems that can affect blood flow when different parts of the circulatory system malfunction. The heart has two upper chambers, called the left and right atria, and two lower chambers, called the left and right ventricles. With each heartbeat, blood moves from one chamber to the next through a series of heart valves.

   How does heart failure affect the body?

   • Heart failure, also known as congestive heart failure, is when the heart does not function as well as it should in pumping blood and oxygen around the body. This can damage the organs and cause extra fluid to build up in the body. Heart failure occurs when the heart muscle becomes too weak to effectively pump blood around the body.

   What causes irregular heartbeats?

   • Narrowed arteries in the heart or high blood pressure can slowly make the heart weak or stiff. This can make it harder for the heart to pump blood. Irregular heart rhythms, called arrhythmias. If the heart doesn't get enough blood, changes in heart signaling can happen. This can cause irregular heartbeats.
