what is atrial fibrilliation?
irregular electrical impulses in the atrium.
how does atrial fibrillation happen?
when the electrical signals in the top chambers (atria) of your heart do not get sent out properly. They should be steady and regular, but instead they quiver or twitch (fibrillation). This causes your heart to beat randomly, which means it does not pump blood as well as it should.
what is a risk of having Atrial fibrilliation?
create blood clots in the heart that may cause a stroke.
what are symptoms of AF?
chest pain, tiredness, shortness of breath, dizziness, finding it hard to exercise, palpations
what medication can you use for atrial fibrillation?
medication such as beta blockers and anti-arrhythmic drugs
ablation
cardioversion
having a pacemaker fitted.
Anticoagulant drugs and DOACs
what is Abdominal aortic aneurysm?
Your abdominal aorta is usually about 2cm wide or about the width of a garden hose. If you have an aneurysm it can grow from 3cm to over 5.5cm wide.
what are symptoms of abdominal aortic aneurysm?
a pulsating feeling in your stomach
pain in your stomach
persistent back pain.
what is the Causes of abdominal aortic aneurysm
It’s not known exactly what causes abdominal aortic aneurysm although it’s linked to atherosclerosis and the build-up of fatty material in your arteries.
what is the treatment of abdominal aortic aneurysm?
no treatment is required if t is under 4.4cm
however if it is over:
endovascular repair (EVAR) is a type of keyhole surgery. This involves placing a stent-graft (a small metal tube covered with a mesh) inside the artery through a small cut in the groin
surgical repair involves replacing the affected part of your aorta with a plastic tube (graft).
what is angina?
t’s a pain or an uncomfortable feeling when blood flow to your heart is reduced. It’s not dangerous but it can be a sign of heart problem, like coronary heart disease.
what are symptoms of angina?
pressure, tightness or squeezing in your chest. This can feel painful or like a dull ache. You might also feel it in your shoulders, arms, neck, jaw, back or stomach.
what is Vasospastic angina
during the night when you’re resting, when a coronary artery supplying blood and oxygen to your heart goes into spasm and narrows or tightens, and lets less blood through.
what is Microvascular angina
usually happens when you’re under physical pressure, like when you’re exercising, or you’ve been stressed or anxious
what is angina caused by?
The most common cause is coronary heart disease. This is when the arteries that supply your heart muscle with blood and oxygen are narrowed by a fatty substance called plaque.
how is angina treated?
medications such as GTN spay or pills
coronary angioplasty where a special kind of balloon is gently inflated to open a narrowed artery.
Many people also have a type of mesh called a stent inserted to keep the artery open
what is Arrhythmia?
Arrhythmias are caused by a problem in this conduction system, which can make your heart beat too slowly, too quickly, or in an irregular way.
what are the different types of arrhythmias?
AF- irregular
Supraventricular
tachycardia (SVT)- very fast
atrial flutter- when the top chambers of the heart contract faster compared to lower
tachybrady- fast or slow
heartblocks-delay or blockage in the conduction system between the top and bottom chambers of the heart which can cause a slow heart rate.
what are the causes of arrhythmias?
a heart attack
heart failure
cardiomyopathy
coronary heart disease.
what is Atherosclerosis?
build-up of fatty material (atheroma) inside your arteries. It’s a potentially serious condition that causes most heart attacks and strokes but often goes unnoticed.
what is Atherosclerosis?
build-up of fatty material (atheroma) inside your arteries. It’s a potentially serious condition that causes most heart attacks and strokes but often goes unnoticed.
what are symptoms of atherosclerosis?
chest pain
confusion, as a result of blood not flowing to your brain
difficulty breathing
feeling very tired
pain in any of your limbs, where there may be a blocked artery
weak muscles
how is atherosclerosis treated?
lifestyle change, diet change, coronary bypass surgery or a coronary angioplasty, medicances to reduce high bp or the risk of blood clots
what is a cardiac arrest?
A cardiac arrest is when your heart suddenly stops pumping blood around your body.
what causes a cardiac arrest?
dangerous abnormal heart rhythm (arrhythmia), which happens when the electrical system in the heart isn’t working properly.
