Draw the pressure vume loop in symptoms of Left heart failure and Right heart failure

Here are the pressure-volume loops for left heart failure and right heart failure.

Left Heart Failure:

In left heart failure, the left ventricle's ability to pump blood is impaired. This leads to a reduced stroke volume and increased end-systolic volume. The loop will be shifted downwards and to the left.

• Reduced Stroke Volume: The difference between end-diastolic volume and end-systolic volume is smaller.
• Increased End-Systolic Volume: The ventricle doesn't empty as effectively.
• Increased End-Diastolic Pressure: Due to blood backing up into the left atrium and pulmonary circulation.

Right Heart Failure:

In right heart failure, the right ventricle's pumping function is compromised. This results in a reduced stroke volume and increased end-systolic volume in the right ventricle. The loop will also be shifted downwards and to the left, similar to left heart failure, but affecting the right side.

• Reduced Stroke Volume: Similar to left heart failure, the ejection fraction is lower.
• Increased End-Systolic Volume: The right ventricle retains more blood after contraction.
• Increased End-Diastolic Pressure: Blood backs up into the right atrium and systemic circulation, leading to peripheral edema.
