  • What is a Vasovagal Syncope response?

    Vasovagal syncope, also known as neurocardiogenic syncope or reflex syncope, is the most common cause of fainting, accounting for approximately 50% of all syncopal episodes. It occurs when there is a sudden drop in blood pressure and heart rate, causing a temporary loss of consciousness. This condition is typically benign and not associated with any…

  • 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…

  • APGAR Score – Newborn assessment

    The APGAR tool is a quick assessment used to evaluate the physical condition of a newborn baby immediately after birth. The tool was developed by Dr. Virginia Apgar in 1952 and has since become a standard practice in obstetrics. APGAR is an acronym that stands for Appearance, Pulse, Grimace, Activity and Respiration. The tool involves…

  • Cardiac Output – CO = SV x HR

    Cardiac Output = Stroke Volume x Heart RateCO = SV x HR Cardiac Output is a measure of the amount of blood pumped by the heart in one minute. It is calculated by multiplying the stroke volume (the amount of blood pumped out of the heart with each beat) by the heart rate (the number…

  • Ventricular Tachycardia (VT)

    Ventricular tachycardia (VT) is a type of irregular heartbeat that originates from the lower chambers of the heart (the ventricles). It is characterised by a rapid heart rate, typically greater than 100 beats per minute, and can be a potentially life-threatening condition. VT can occur in people of all ages, but it is more common…

  • Mean Arterial Pressure (MAP)

    MAP = diastolic pressure + (systolic pressure – diastolic pressure) / 3 Mean arterial pressure (MAP) is a measure of the average blood pressure in a patients arteries over the course of a cardiac cycle, which is one complete heartbeat. It is calculated by taking into account both the systolic and diastolic blood pressures. 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…
