What Happens When the Electrical Activity of Your Heart Changes?

What Happens When the Electrical Activity of Your Heart Changes?

The heart's electrical conduction system plays a very important role in cardiovascular functioning. Also known as the atrioventricular (AV) conduction system, it regulates and controls the timing of the heartbeat.

How does the heart's electrical conduction system work?

There is a collection of electrical cells in the upper right atrium of the heart known as the sinoatrial (SA) node which acts as a natural pacemaker and generates electrical signals. These signals travel through specialized electrical pathways and stimulate the muscular walls of the heart to contract in a rhythmic manner. This gives rise to the heartbeat that pulses at a specific frequency every minute.

What is the effect of fluctuations in electrical activity on the heart?

The standard heart rate in human being ranges from 60 to 100 beats per minute. It slows down when a person sleeps and speeds up when one experiences physical or emotional heightening. These fluctuations are triggered by the brain or other systems of the body and signal the SA node to generate charges more rapidly or slowly. This leads to spikes and drops in the heart rate, depending on the nature of the situation.

What happens when there is dysfunction in the heart's electrical activity?

When the heart's electrical conduction system does not function properly, it leads to the occurrence of a condition known as arrhythmia or abnormal heart rhythm. This happens when electrical impulses are generated in an irregular manner and causes tachycardia (rapid heartbeats) or bradycardia (slow heartbeats) which takes place in jarring infrequent tempos.

What causes fluctuations in the heart's electrical activity?

There are various kinds of triggers that cause the heart rate to fluctuate. The exact nature of fluctuation also depends on the type of trigger. A few everyday examples of these causes are as follows:
- Exercise and strenuous physical activity increases electrical activity as the heart is required to beat faster so as to increase the supply of blood and oxygen to the muscles.
- Sleep and rest reduce heart rate as the body is not needed to exert itself.
- Release of adrenaline into the bloodstream causes the heart rate to spike up.

My dad has a heart pain prob and he feels giddy.what should he do?
Examples of heart-related causes of chest pain include: Heart attack. A heart attack is a result of a blood clot that's blocking blood flow to your heart muscle. Angina. Thick plaques can gradually build up on the inner walls of the arteries that carry blood to your heart. These plaques narrow the arteries and restrict the heart's blood supply, particularly during exertion. Aortic dissection. This life-threatening condition involves the main artery leading from your heart — your aorta. If the inner layers of this blood vessel separate, blood will be forced between the layers and can cause the aorta to rupture. Pericarditis. This condition, an inflammation of the sac surrounding your heart, usually causes sharp pain that gets worse when you breathe in or when you lay down. Digestive causes Chest pain can be caused by disorders of the digestive system, including: Heartburn. This painful, burning sensation behind your breastbone occurs when stomach acid washes up from your stomach into the esophagus — the tube that connects your throat to your stomach. Swallowing disorders. Disorders of the esophagus can make swallowing difficult and even painful. Gallbladder or pancreas problems. Gallstones or inflammation of your gallbladder or pancreas can cause abdominal pain that radiates to your chest. Muscle and bone causes Some types of chest pain are associated with injuries and other problems affecting the structures that make up the chest wall. Examples include: Costochondritis. In this condition, the cartilage of your rib cage, particularly the cartilage that joins your ribs to your breastbone, becomes inflamed and painful. Sore muscles. Chronic pain syndromes, such as fibromyalgia, can produce persistent muscle-related chest pain. Injured ribs. A bruised or broken rib can cause chest pain. Lung-related causes Many lung disorders can cause chest pain, including: Pulmonary embolism. This cause of chest pain occurs when a blood clot becomes lodged in a lung (pulmonary) artery, blocking blood flow to lung tissue. Pleurisy. If the membrane that covers your lungs becomes inflamed, it can cause chest pain that's made worse when you inhale or cough. Collapsed lung. The chest pain associated with a collapsed lung typically begins suddenly and can last for hours. A collapsed lung occurs when air leaks into the space between the lung and the ribs. Pulmonary hypertension. High blood pressure in the arteries carrying blood to the lungs (pulmonary hypertension) also can produce chest pain. Other causes Chest pain can also be caused by: Panic attack. If you have periods of intense fear accompanied by chest pain, rapid heartbeat, rapid breathing, profuse sweating, shortness of breath, nausea, dizziness and a fear of dying, you may be experiencing a panic attack. Shingles. Caused by a reactivation of the chickenpox virus, shingles can produce pain and a band of blisters from your back around to your chest wall. So for heart related cause there are many effective medicines to prevent that pain like arjunarishta....hridyarnava ras....akeek pishti....if breathlessness then shwas kutha ras....shwas chintamani ras....etc....avoid oily food...spicy food...junk food....etc

Your blood pressure is upper limit of the normal. Follow life style modification like salt restricted diet, walking, weight reduction. Other than dizziness, if you have any complaints, or if dizziness is persistent or increasing, it needs to be investigated.

you can take..tab.vit.D..OD. AND CAP.ZEVIT FOR MORNING TIREDNESS . Symptoms and Health Risks of Vitamin D Deficiency Symptoms of bone pain and muscle weakness can mean you have a vitamin D deficiency. However, for many people, the symptoms are subtle. Yet, even without symptoms, too little vitamin D can pose health risks. Low blood levels of the vitamin have been associated with the following: Increased risk of death from cardiovascular disease Cognitive impairment in older adults Severe asthma in children Cancer Research suggests that vitamin D could play a role in the prevention and treatment of a number of different conditions, including type1 and type 2 diabetes, hypertension, glucose intolerance, and multiple sclerosis. Causes of Vitamin D Deficiency Vitamin D deficiency can occur for a number of reasons: You don't consume the recommended levels of the vitamin over time. This is likely if you follow a strict vegan diet, because most of the natural sources are animal-based, including fish and fish oils, egg yolks, cheese, fortified milk, and beef liver. Your exposure to sunlight is limited. Because the body makes vitamin D when your skin is exposed to sunlight, you may be at risk of deficiency if you are homebound, live in northern latitudes, wear long robes or head coverings for religious reasons, or have an occupation that prevents sun exposure. You have dark skin. The pigment melanin reduces the skin's ability to make vitamin D in response to sunlight exposure. Some studies show that older adults with darker skin are at high risk of vitamin D deficiency.
