Secondary Hypertension: When and How to Investigate

…referred to a specialized centre because the work up may require expertise and technologies unavailable in primary care. Before investigating secondary causes, pseudo resistance must…

P-wave, PR interval, PR segment: physiology, criteria & ECG findings

…the right atrium is commonly a consequence of increased resistance to empty blood into the right ventricle. This may be due to pulmonary valve stenosis…

Circulatory and haemodynamic parameters

…resistance and oxygen transport Formulas Mean arterial pressure (MAP) = diastolic + (systolic − diastolic)/3 Cardiac output = stroke volume × heart rate SVR = 80 × (MAP…

Hypertrophic Cardiomyopathy (HCM) & Hypertrophic Obstructive Cardiomyopathy (HOCM)

…systemic resistance makes it more difficult for the ventricle to eject blood into the aorta during systole. In aortic stenosis, there is increased resistance in…

🟠 Hydralazine

…counteracted with simultaneous administration of beta blockers). Effects Induces arteriolar vasodilation without effects on venous circulation. The reduction in systemic vascular resistance (SVR) is rapid…

Aortic stenosis

…As the valve area becomes smaller, the transvalvular resistance increases, making it more difficult to eject blood into the aorta. In the early stages of…

Pulmonary Embolism (PE)

…Pathophysiology of pulmonary embolism (PE). Hemodynamic effects Pulmonary embolism leads to increased resistance in the main pulmonary artery, and thereby increased afterload on the right…
