Heart rate vs Pulse rate
Heart rate represents the number of heartbeats per minute, pulse rate reflects the palpable pulsations of arteries. What is Heart Rate? Heart rate refers to the number of times the heart beats per minute. It serves as a measure of the heart’s pumping capacity and overall cardiac function. Factors such as age, fitness level and…

Cardiac Cycle
The cardiac cycle is the sequence of events that occur in the heart during one complete heartbeat, starting with the contraction (systole) of the ventricles, followed by the relaxation (diastole) of the ventricles. The cycle includes the filling of the ventricles with blood during diastole and the ejection of blood into the circulatory system during…

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…

Electrocardiogram (ECG)
A typical heart beat on an electrocardiogram (ECG) consists of several components, including the P wave, the QRS complex, and the T wave. The P wave represents the electrical activity of the atria, the upper chambers of the heart, as they contract and pump blood into the ventricles, the lower chambers of the heart. The…
