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…

Myocardial Infarction
A myocardial infarction (MI), also known as a heart attack, is a serious medical condition that occurs when the blood flow to a part of the heart is blocked, causing damage or death of heart muscle cells. The most common cause of a heart attack is a blockage in one of the coronary arteries, which…

Ventricular Fibrillation (VF)
Ventricular fibrillation (VF) is a type of cardiac arrhythmia in which the ventricles of the heart contract in a rapid and disorganised manner, resulting in an ineffective pumping of blood. VF is a potentially life-threatening condition that requires immediate medical attention. VF is often the result of an underlying heart condition, such as coronary artery…

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…

Pneumonia
Pneumonia is an infection of the lungs that can be caused by a variety of microorganisms, including bacteria, viruses, and fungi. The infection causes inflammation in the air sacs of the lungs (alveoli), which can fill with fluid or pus, making it difficult to breathe and leading to coughing, chest pain and difficulty breathing. Symptoms…
