  • Atrial Flutter – Pathophysiology and symptoms

    Atrial flutter is a type of heart rhythm disorder that occurs when the electrical impulses in the atria of the heart beat rapidly and regularly in a circular pattern. This rapid and regular electrical activity causes the atria to contract rapidly and irregularly, which can lead to symptoms such as palpitations, shortness of breath and…

  • Thrombus

    A thrombus is a blood clot that forms within a blood vessel. It is also sometimes referred to as a “clot.” A thrombus can form in any part of the circulatory system, including the heart, veins, and arteries. Thrombi can form in response to injury, trauma or inflammation of the blood vessels. They can also…

  • Stroke

    A stroke is a medical emergency that occurs when the blood supply to the brain is interrupted, resulting in damage to brain cells. There are two main types of stroke: ischemic stroke, which is caused by a blocked blood vessel, and hemorrhagic stroke, which is caused by bleeding in the brain. The symptoms of a…

  • Transient Ischemic Attack (TIA)

    A Transient Ischemic Attack (TIA), is also known as a “mini-stroke.” It occurs when the blood supply to a part of the brain is briefly interrupted, usually by a blood clot. TIAs are caused by temporary blockages in the blood vessels that supply blood to the brain. Symptoms of a TIA are similar to those…

  • Ischemia, Infarction and Necrosis

    Ischemia, a lack of blood flow and oxygen to the body’s tissues, is often a precursor to infarction, which is the death of tissue due to a lack of blood flow and oxygen. Prolonged ischemia can lead to cell death and the formation of a necrotic area, which is characterised by the death of cells…

  • Atrial Fibrillation (AF)

    Atrial fibrillation (AF or AFib) is a type of heart rhythm disorder that affects the upper chambers of the heart (atria). It is characterised by rapid and irregular electrical impulses in the atria that cause the heart to beat in a fast and irregular manner. In AF, the normal electrical signals that coordinate the contraction…
