Sick Sinus Syndrome in Heart Disease
Any irregularity in your heart’s natural rhythm is called an arrhythmia. Almost everyone’s heart skips a beat now and again, and these mild palpitations are usually harmless.
Electrical impulses from the heart muscle (the myocardium) cause the heart to beat (contract). This electrical signal begins in the Sinoatrial Node, also called the SA node or the sinus node. The SA node is located at the top of the heart’s upper-right chamber (the right atrium). The SA node is sometimes called the heart’s “natural pacemaker.” When an electrical impulse is released from the SA node, it causes the heart’s upper chambers to contract.

Myocarditis
The myocardium is the muscular wall of the heart, or the heart muscle. It contracts to pump blood out of the heart, and then relaxes as the heart refills with returning blood. The myocardium’s smooth outer membrane is called the epicardium. Its inner lining is called the endocardium.

What is peripheral vascular disease?
Peripheral artery disease (PAD) is a heart condition similar to that of coronary artery disease and carotid artery disease. In PAD, the fatty deposits build up in the inner linings of the artery walls. These blockages restrict the blood flow circulation, mainly in arteries leading to the kidneys, stomach, arms, legs and feet.
