Transcript of Atrial Fibrillation

Atrial Fibrillation By: Lawrence Gomes But what is Atrial Fibrillation? Atrial Fibrillation is the most common form of cardiac arrhythmia (irregular heart beat). It occurs when electrical impulses created by the sinoatrial node get overwhelmed by chaotic electrical impulses in the roots of the pulmonary veins. This amounts to the formation of an irregular heart beat in the ventricles. How do I know if I have A-Fib? Other than having an irregular heartbeat, there really are no other symptoms for A-Fib. However... Atrial Fibrillation is often associated with: palpitations, fainting, chest pains, or congestive heart failure. Diagnosis How does A-Fib affect the heart? The average human heart rate is 60-100 times per minute, but the heart rate of someone with A-Fib can range from 300-600 beats per minute. With each heart beat the heart pumps blood throughtout the body. A-Fib makes it difficult for the heart to pump blood to the rest of the body. When the atria experiences the chaotic electrical impulses, it causes the ventricles to beat too quickly. This prevents the ventricles from becoming full of blood, before it pumps to the body. Which can lead to an insufficient blood supply in major parts of the body. To be diagnost with A-Fib you must get your heart
rate checked. This can be done by checking your pulse, but the most effective diagnosis is an electrocardiogram(ECG). "Schematic diagram of normal sinus rhythm for a human heart as seen on ECG. In atrial fibrillation, however, the P waves, which represent depolarization of the atria, are absent." Can A-Fib be treated? Medications Electrical Cardioversion Surgery Lifestyle Changes Treatments Conveniently there are many options to treat Atrial Fibrillation, such as:
Electrical cardioversion
Lifestyle changes Most medications prescribed to those with A-Fib are either rhythm control or rate control drugs. Rhythm control helps return the heart to its normal sinus rhythm. Examples of rhythm control drugs are Pronestyl, Norpace, and Tambocor. Rate control helps regulate and slow down heart rate during atrial fibrillation. Examples of rate control drugs are Lanoxin, Calan, and Cardizem. Rhythm control Rate Control Electrical Cardioversion is a method used to reset the heart's normal rhythm. Typically the maze procedure, where a series of intricate incisions are made in order to define the paths of electrical impulses Lifestyle changes that could reduce atrial fibrillation are:
Quitting smoking
Reduce alcohol use
Reduce caffeine intake In Conclusion... Atrial Fibrillation is the most common form of irregular heartbeat that is a result of uncontrollable electrical impulses. There are no specified symptoms, but it is associated with palpitations, fainting, chest pain, or congestive heart failure. The most effecient way to be diagnosed with A-Fib is by electrocardiogram and the treatments include: medication, lifestyle changes, electrical cardioversion and surgery.
