Treatments for Atrial Fibrillation
Atrial Fibrillation can be treated with antibiotics, such as anticoagulants to prevent clotting and rhythm control medication. There can also be therapy to shock the heart back to its normal rhythm, known as cardioversion.In very rare cases, there may be surgery involved to remove tissue or correct structural abnormalities in the heart that causes AFib.
Cardiac Cycle Events
The cardiac cycle events describe what occurs in single heartbeat.Specifically, there are no defined p-waves and an irregular rhythm seen. Valve status: Valvular; the mitral valve is leaky and can cause the atria to enlarge in volume, worsening the condition. Blood flow: Inefficient pumping leads to a lack of blood flow, causing pooling which leads to strokes Pressure: Varying, but is usually low because of inconsistent, weaker pumps Volume: Enlargement of the left atria can specifically be the contributor to AFib because it directly pumps blood to the pulmonary system, affecting breathing
Electrical Events: Chaotic and erratic signals lead to unsynchronized pumping causes the atria to "quiver" instead of forcing one strong pump. Heart Sounds: Comes in bursts, the lub-dub is not rhythmic and can even sound like it skips a beat
Atrial Fibrillation in Physiology Terms
Atrial Fibrillation is where there is insufficient ventricular filling of blood (diastole) because the atria does not contract at a strong, consistent interval (atrial systole). This is a disruption of diastole, which causes less blood to flow into the atria, leading to a lack of exchange of oxygen, hence why there is shortness of breath. The atria contract much more irregularly because of rapid, erratic electrical signals that cause contraction at a faster, yet inconsistent rate.
What is Atrial Fibrillation?
Atrial Fibrillation (AFib) is a common heart rhythm disorder that is due to the upper heart chambers beating chaotically and irregularly. These beat out of sync with the lower chambers. This ultimately causes shortness of breath and light-headedness.Atrial Fibrillation can happen in episodes. It isn't a life-threatening disorder, but requires treatment to prevent strokes from occurring.
Kinesthetic and The Study Guide
The "K" in VARK known as Kinesthetic (strong) was my top learning method. This method includes a preference for application/ptractical examples, experiences, case studies (such as this one), and speaking with others whether the source is from my peers or the professor.
- An interactive poster is what I've decided to use for this case study
- The case study assignment in itself includes an applicable, real-life example that helps with learning about the heart
- Being able to also discuss topics online/in-person helps with retaining information
