The heart works by a regulated series of events that cause this muscular organ to contract (squeeze to push blood) and then relax (refill with blood). One heartbeat is a single cycle in which your heart contracts and relaxes to pump blood. At rest, the normal heart beats approximately 60 to 100 times every minute, and it increases when you exercise.

Aerobic exercise is where you’re moving your body’s largest muscles, such as the ones in your arms and legs, in a way that makes you warm and slightly out of breath. Aerobic exercise examples include walking, cycling, and swimming but also everyday activities such as doing housework, gardening, or playing with your children or grandchildren. Benefits of aerobic exercise? In arrhythmogenic cardiomyopathy (ACM), the proteins that usually hold the heart muscle cells together are abnormal. Muscle cells can die and the dead muscle tissue is replaced with fatty and fibrous scar tissue.Your doctor will ask about your medical history, symptoms and examine you. You may then be sent for tests such as:

The leaflets of the mitral and tricuspid valves are also supported by tough, fibrous strings called chordae tendineae. Your heart is divided into four chambers. You have two chambers on the top (atrium, plural atria) and two on the bottom (ventricles), one on each side of the heart. Left atrium: After the lungs fill blood with oxygen, the pulmonary veins carry the blood to the left atrium. This upper chamber pumps the blood to your left ventricle. Living a healthier lifestyle can be hard at first, but it’s important for your overall quality of life.

These impulses move down cells toward the AV node ( atrioventricular node), another cluster of cells located near the center of the heart between the bottom of the right atria and the top of the ventricles. If you can’t walk or find it difficult to balance, you can still do aerobic exercise by moving your arms and top half of your body, for example you could try out these seated exercises. On the other hand, spending time with people we like, and who like and respect us, has all sorts of health benefits, from boosting our immune system and perceptions of stress, to reducing our risk of anxiety, depression and physical illness.” The human heart is about the size of a human fist and is divided into four chambers, namely two ventricles and two atria. The ventricles are the chambers that pump blood and the atrium are the chambers that receive blood. Among these both the right atrium and ventricle make up the “right heart,” and the left atrium and ventricle make up the “left heart.” The structure of the heart also houses the biggest artery in the body – the aorta. Helen Alexander, a physiotherapist who specialises in cardiac rehabilitation at Nuffield Health at St Bartholomew's Hospital, has the lowdown on the best types of exercise – and how you might need to adapt it, depending on your condition: Aerobic exercise
