What is the firillation instead of pumping strongly the heart muscle quivers ineffectively?
Fibrillation is an irregular and rapid heart rhythm that causes the heart muscle to quiver instead of pumping effectively. This can lead to inefficient blood flow and potential complications like blood clots or heart failure. Treatment may involve medications, electrical cardioversion, or other interventions to restore normal heart rhythm.
What is the reason for SCD?
Sudden cardiac death is usually caused by ventricular fibrillation (the lower chamber of the heart quivers instead of pumping in an organized rhythm).
Is tachycardia and fibrillation are the same?
No, tachycardia is merely a fast heart rate and depending on the age will determine this. Fibrillation is the left ventricle fibrillating or twitching and not really pumping at all and this is life threatening whereas, tachycardia is not.
Is atrial fibrillation worse that ventricular fibrillation?
No, ventricular fibrillation is worse than atrial fibrillation. This is because the ventricle is the chamber responsible for the main force pumping the blood out of the heart. If this contraction is not coordinated (like when fibrillation occurs), then the heart will not be able to function and consciousness will be lost within a few seconds. Ventricular fibrillation may result from electric shock, major myocardial infarct or some anaesthetic drugs. Resuscitation is usually possible by applying an electric shock (defibrillation) - which causes all cells to enter the refractory period and gives the sinoatrial node a chance to resume its normal pacemaker activity.
What is the cardiac output during fibrillation?
During fibrillation, the heart's rhythm becomes chaotic and ineffective at pumping blood. As a result, there is no coordinated contraction of the heart muscle, leading to a significant decrease in cardiac output. This can result in severe consequences if not promptly managed.
What are some of the negative health effects that atrial fibrillation can have on ones' body?
Some negative side or health effects that atrial fibrillation can have on ones body are stroke because your heart beats faster and irregularly Your heart stops pumping blood to your brain and thus causes a stroke.
How do they do a echo test?
An echocardiogram shows how well your heart is pumping. As a muscle, all parts of the heart must contract and relax in a sequence. With certain heart problems, part of the heart might contract ineffectively or not at all. The echocardiogram gives important diagnostic information.
Caused by irregular contractions of the atrial myocardium?
Atrial fibrillation is caused by rapid and irregular contractions of the atrial myocardium, leading to ineffective pumping of blood from the atria. This irregular heart rhythm can increase the risk of blood clots and other complications if left untreated. Treatment options may include medication, electrical cardioversion, or catheter ablation.
What is AED's?
It stands for Automated External Defibrillator. This is a medical device that monitors a person's heartbeat. If the heart is beating in the wrong way (fibrillation) it is not pumping blood. The AED detects that, and send an electrical shock through a wire connected to the patient to change the heartbeat.
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.
Does afib cause tiredness?
Yes - as during atrial fibrillation the heart is not pumping what it should, this results in a drop in o2 being delivered to the brain that can cause a feeling of being extremely tired. Some people, remarkably, live with this and adjust to it.
What does low voltage frontal leads mean in an EKG?
more than likely misplacement of the electrodes, but low voltage could also indicate a small heart or perhaps a heart that isn't pumping very strongly.
