The heart beat is caused by electrical impulses causing the muscle to contract and relax. This electrical signal begins in the Sinoatrial Node, also called the SA node or the sinus node. The SA node is positioned at the top of the heart's upper-right chamber (the right atrium). The SA node is sometimes called the heart's "normal pacemaker." When an electric impulse is released from the SA node, it reasons the heart's upper chambers to contract.
Sick sinus syndrome is a type of arrhythmia. This is a obvious sign that the sinoatrial node is not running optimally. The SA node by and large sends electric impulses at a particular rate, but if the SA node is not running properly, the heart may beat too quick, too slow, or both .
Sick sinus syndrome by and large develops gradually over many years, and the reasons are not always identified . Mature adults over the age of fifty have the highest rate of sick sinus syndrome but it is also identified to occur in kids who have had heart surgery.
The problems are not by and large evident. Or they do not think their problems are significant enough for them to see a medical professionsal . Some signs and problems of sick sinus syndrome are fainting, being dizzy, confusion that comes and goes, feeling the hear has skipped a beat (palpitations), chest pain, angina, weariness, shortness of breathe aching muscles.
The patient may not show many problems which makes sick sinus syndrome tremendously hard to diagnose. The medical doctor will take a health history, ask about problems, and listen to the heart with a stethoscope. With the stethoscope, the health care professional may be able to hear an abnormal heartbeat, which can be a sign of sick sinus syndrome.
Peripheral Vascular Disease
Peripheral artery disease (PAD) is a heart condition similar to that of coronary blood vessel disease and carotid artery disease. In PAD, the fatty deposits build up in the internal linings of the blood vessel walls . These blockages restrict the blood flow circulation, mainly in arteries leading to the kidneys, stomach, arms, legs and feet .
Many people experience cramps in their legs when working out. This generally goes away when the person stops what exercise they are doing. This is called "intermittent claudication." People with PAD often have fatty buildup in the arteries of the heart and brain. Because of this association, most people with PAD have a higher risk of death from heart attack and stroke.
There are two types of these circulation disorders:
Functional peripheral vascular diseases don't have an organic cause. They don't involve defects in blood vessels' structure. They're usually short-term effects related to "spasm" that may come and go . Raynaud's disease is an example. It can be triggered by cold temperatures, emotional stress, working with vibrating machinery or smoking .
Organic peripheral vascular diseases are brought about by structural changes in the blood vessels, such as swelling and tissue damage. Peripheral artery disease is an example. It's triggered by fatty buildups in arteries that block normal blood flow.
How is peripheral artery disease diagnosed and treated?
Techniques used to establish PAD include a health history, physical exam, ultrasound, X-ray angiography and magnetic resonance imaging angiography (MRA).
Most people with PAD can be treated with lifestyle changes, medications or both. Lifestyle transformations to lower your risk include stopping smoking, diabetes control and blood pressure. Become physically active; eat a low-saturated-fat, low-cholesterol diet.
PAD may require drug treatment, too. Drugs include medicines to help improve walking distance, antiplatelet agents and cholesterol-lowering agents (statins).
