Chambers of the Heart

The heart is a muscular organ near the size of a fist, located just behind and slightly left of the breastbone. The center pumps blood through the network of arteries and veins called the cardiovascular system.

The middle has four chambers:

• The right atrium receives blood from the veins and pumps it to the right ventricle.
• The right ventricle receives blood from the correct atrium and pumps information technology to the lungs, where it is loaded with oxygen.
• The left atrium receives oxygenated claret from the lungs and pumps it to the left ventricle.
• The left ventricle (the strongest chamber) pumps oxygen-rich blood to the residual of the body. The left ventricle's vigorous contractions create our blood pressure.

The coronary arteries run along the surface of the eye and provide oxygen-rich blood to the centre muscle. A web of nervus tissue also runs through the heart, conducting the circuitous signals that govern contraction and relaxation. Surrounding the heart is a sac chosen the pericardium.

Heart Conditions

• Coronary artery disease: Over the years, cholesterol plaques tin narrow the arteries supplying blood to the heart. The narrowed arteries are at higher take chances for  consummate blockage from a sudden claret clot (this blockage is chosen a heart assail).
• Stable angina pectoris: Narrowed coronary arteries crusade predictable chest pain or discomfort with exertion. The blockages forestall the heart from receiving the actress oxygen needed for strenuous activity. Symptoms typically go better with rest.
• Unstable angina pectoris: Chest pain or discomfort that is new, worsening, or occurs at residue. This is an emergency situation as it can precede a heart attack, serious abnormal centre rhythm, or cardiac arrest.
• Myocardial infarction (center assault): A coronary artery is suddenly blocked. Starved of oxygen, part of the heart muscle dies.
• Arrhythmia (dysrhythmia): An abnormal heart rhythm due to changes in the conduction of electric impulses through the middle. Some arrhythmias are benign, but others are life-threatening.
• Congestive heart failure: The heart is either too weak or too stiff to effectively pump blood through the trunk. Shortness of breath and leg swelling are common symptoms.
• Cardiomyopathy: A disease of heart muscle in which the heart is abnormally enlarged, thickened, and/or stiffened. As a event, the heart's power to pump blood is weakened.
• Myocarditis: Inflammation of the center muscle, nigh often due to a viral infection.
• Pericarditis: Inflammation of the lining of the heart (pericardium). Viral infections, kidney failure, and autoimmune conditions are mutual causes.
• Pericardial effusion: Fluid between the lining of the center (pericardium) and the center itself. Oft, this is due to pericarditis.
• Atrial fibrillation: Abnormal electric impulses in the atria cause an irregular heartbeat. Atrial fibrillation is one of the most mutual arrhythmias.
• Pulmonary embolism: Typically a blood clot  travels through the heart to the lungs.
• Heart valve illness: There are four heart valves, and each tin develop problems. If severe, valve disease can cause congestive heart failure.
• Center murmur: An aberrant audio heard when listening to the heart with a stethoscope. Some center murmurs are benign; others advise eye illness.
• Endocarditis: Inflammation of the inner lining or heart valves of the eye. Normally, endocarditis is due to a serious infection of the heart valves.
• Mitral valve prolapse: The mitral valve is forced astern slightly after blood has passed through the valve.
• Sudden cardiac death: Death caused past a sudden loss of middle function (cardiac arrest).
• Cardiac arrest: Sudden loss of middle function.

Heart Tests

• Electrocardiogram (ECG or EKG): A tracing of the heart'due south electrical activity. Electrocardiograms can assistance diagnose many heart weather.
• Echocardiogram: An ultrasound of the heart. An echocardiogram provides direct viewing of whatsoever problems with the heart musculus'southward pumping power and centre valves.
• Cardiac stress examination: By using a treadmill or medicines, the centre is stimulated to pump to near-maximum capacity. This may identify people with coronary artery affliction.
• Cardiac catheterization: A catheter is inserted into the femoral artery in the groin and threaded into the coronary arteries. A doc can and then view X-ray images of the coronary arteries or any blockages and perform stenting or other procedures.
• Holter monitor: If a md suspects an arrhythmia, a portable center monitor tin be worn. Called a Holter monitor, it records the centre's rhythm continuously for a 24 hour period.
• Result monitor: If a physician suspects an infrequent arrhythmia, a portable center monitor called an event monitor can be worn. When you develop symptoms, you can push a button to record the heart's electrical rhythm.

Heart Treatments

• Exercise: Regular do is important for center health and virtually heart conditions. Talk to your medico before starting an practice plan if you accept heart problems.
• Angioplasty: During cardiac catheterization, a doctor inflates a balloon within a narrowed or blocked coronary artery to widen the artery. A stent is often then placed to keep the avenue open up.
• Percutaneous coronary intervention (PCI): Angioplasty is sometimes called a PCI or PTCA (percutaneous transluminal coronary angioplasty) past doctors.
• Coronary artery stenting: During cardiac catheterization, a doctor expands a wire metal stent within a narrowed or blocked coronary avenue to open up the area. This lets blood flow improve and tin abort a heart attack or relieve angina (chest pain).
• Thrombolysis: "Clot-busting" drugs injected into the veins can dissolve a blood jell causing a middle attack. Thrombolysis is generally just washed if stenting is not possible.
• Lipid-lowering agents: Statins and other cholesterol (lipid) lowering drugs reduce the risk for heart attack in loftier-gamble people.
• Diuretics: Commonly called water pills, diuretics increase urination and fluid loss. This reduces claret volume, improving symptoms of heart failure.
• Beta-blockers: These medicines reduce strain on the eye and lower centre charge per unit. Beta-blockers are prescribed for many center conditions, including middle failure and arrhythmias.
• Angiotensin-converting enzyme inhibitors (ACE inhibitors): These blood pressure medicines likewise help the eye afterward some eye attacks or in congestive heart failure.
• Aspirin: This powerful medicine helps prevent blood clots (the crusade of heart attacks). Most people who have had heart attacks should have aspirin.
• Clopidogrel (Plavix): A clot-preventing medicine that prevents platelets from sticking together to class clots. Clopidogrel is especially important for many people who take had stents placed.
• Antiarrhythmic medications: Numerous medicines help control the eye's rate and electrical rhythm. These assistance foreclose or control arrhythmias.
• AED (automated external defibrillator): If someone has sudden cardiac abort, an AED can be used to assess the heart rhythm and send an electrical shock to the eye if necessary.
• ICD (Implantable cardioverter defibrillator): If a doctor suspects you are at risk for a life-threatening arrhythmia, an implantable cardioverter defibrillator may be surgically implanted to monitor your centre rhythm and send an electrical shock to the center if necessary.
• Pacemaker: To maintain a stable heart rate, a pacemaker can be implanted. A pacemaker sends electrical signals to the heart when necessary to help information technology beat out properly.
