Which form of cardiac arrhythmia is fatal unless reversed?
Ventricular Fibrillation
What is the prognosis for patients with atrial fibrillation and flutter?
these arrhythmias can cause a blood clot to form in the heart. This can lead to a stroke or a blockage carried by the blood flow (an embolism ) anywhere in the body's arteries. Atrial fibrillation is responsible for about 15% of strokes
What is the medical term meaning a period of contraction within the heart?
Fibrillation is random inffectual contractions of the heart wall. It is called atrial fibrillation when it's in the upper chambers, and ventricular fibrillation when in the lower chambers of the heart.
How many people have irregular heartbeats?
The prevalence of irregular heartbeats, also known as arrhythmias, varies depending on the specific type of arrhythmia and the population being studied. In general, it is estimated that millions of people worldwide have some form of arrhythmia. Common types include atrial fibrillation, which affects around 33.5 million people globally, and ventricular arrhythmias, which can occur in individuals with heart conditions such as coronary artery disease or heart failure. Diagnosing and managing arrhythmias is critical to prevent complications such as stroke or sudden cardiac arrest.
Can Q fever cause atrial fibrillation?
Yes, it could. It would be seen in the chronic form of Q fever.
Are sotalol af and sotalol HCl the same drug?
Yes, sotalol AF (atrial fibrillation) and sotalol HCl (hydrochloride) are the same drug. Sotalol is used to treat certain heart rhythm disorders like atrial fibrillation, and the HCl represents the hydrochloride salt form of sotalol.
Which is more dangerous atrial fibrillation or ventricular fibrillation?
Ventricular fibrillation. Basically the patient is dead. Atrial fibrillation causes an irregular heartbeat because the ventricles are receiving disorganized impulses from the SA node. Ventricular fibrillation is where the SA node and the AV node are not firing and the Purkinje fibers are supplying the electrical impulses to the heart. However, the Purkinje fibers are not able to supply enough electricity to contract the ventricles so the heart is twitching but not beating. A heart that is not beating is not circulating blood which means the patient is dead.
How long does it take a blood clot to form after the onset of Atrial Fibrillation?
A blood clot can begin to form within hours after the onset of atrial fibrillation (AFib). The risk is particularly high within the first 48 hours, as the turbulent blood flow in the heart's atria can lead to clot formation. However, it may take days to weeks for a significant clot to develop, depending on individual risk factors and the duration of AFib. Prompt medical evaluation and treatment are crucial to reduce the risk of stroke associated with AFib.
Pharmaceutical And Surgical Treatment For Atrial Fibrillation?
Atrial fibrillation is the term used for an irregular heartbeat. The condition can be permanent, chronic, or temporary. The cause of most cases of atrial fibrillation is the generation of random electrical signals in the sinus node of the heart that causes irregular beating of the atria as it travels across the atrioventricular node. The actual condition does not, in and of itself, pose a large health risk. Over time, and in patients that have other medical conditions, atrial fibrillation can lead to a host of problems including stroke and heart attack. The basic treatment for atrial fibrillation involves a regiment of medications, usually accompanied by suggested dietary and lifestyle changes. The medications that are given can either attempt to better regulate the heart rate, slow down the heart rate, or speed it up. Often, there are situations where more than one type of medication is prescribed so that they work in tandem to stabilize an irregular heartbeat. For chronic, life threatening, or more severe cases, the treatment for atrial fibrillation can involve surgery or an equally complex procedure. Electro cardioversion is a procedure that applies electrical impulse to the chest over the atria in an attempt to reset the beating pattern of the heart. The procedure, however, is not always successful and sometimes provides only temporary relief. Ablation therapy is a treatment for atrial fibrillation that involves inserting wires or catheters into the heart valves. In this procedure, portions of the atrioventricular node are identified as being the source of any stray electrical pulses to the heart. These areas are then cauterized, after which scar tissue will form in time, blocking any stray signals from passing into other nodes of the heart, eliminating the irregular heartbeat. If all other options fail, however, it is possible that a pacemaker might need to be permanently implanted to regulate the heart. With almost all forms of treatment for atrial fibrillation, one of the common factors is placing the patient on anticoagulant medications that thin the blood and prevent clots from forming that could cause strokes. Additionally, most patients who have to undergo treatment for atrial fibrillation usually have to make lifestyle changes such as quitting smoking, avoiding caffeine and alcohol, and restricting intake of medications that might contain stimulants.
What is adjective form for atria?
atrial
What is the most common type of atrial septal defect?
occurs in the middle of the atrial septum and accounts for about 70% of all atrial septal defects. Abnormal openings can form in the upper and lower parts of the atrial septum as well.
Which organ do Cardiac muscles control?
Cardiac muscles form the heart.
