The video “Pathophysiology” is part of the lecture “Heart Failure” of the online medical course “Cardiology: Advanced”. It provides an excellent insight on compensatory systems of the heart.
You will learn more about:
• Compensatory systems of the heart
• Starling’s law
• Stroke volume
• Cardiac output
• Heart failure because of depression of myocardial and hence ventricular contractility
• Four compensatory mechanisms:
• Sympathetic nervous system stimulation
• Myocardial hypertrophy
• Renin-angiotensin system activation
• Increased heart rate
• Ventricular remodeling: Left ventricular hypertrophy and left ventricular dilatation
