High-output heart failure is a heart condition that occurs when the cardiac output is higher than normal because of increased peripheral demand. There is a circulatory overload which may lead to pulmonary edema secondary to an elevated diastolic pressure in the left ventricle .
High-output heart failure can occur when there is increased cardiac demand that results in increased left ventricular diastolic pressure which can develop into pulmonary congestion (pulmonary edema). [46] Several terms are closely related to heart failure and may be the cause of heart failure, but should not be confused with it.
The term diastolic dysfunction is sometimes erroneously applied in this circumstance, when increased fluid volume retention causes the heart to be over-filled (high output cardiac failure). [ 29 ] Although the term diastolic heart failure is often used when there are signs and symptoms of heart failure with normal left ventricular systolic ...
In effort to compensate the heart will increase cardiac output and heart rate, which accounts for the increased pulse pressure and sinus tachycardia. [1] The condition sometimes accompanies septic shock, preeclampsia, and other physiological and psychiatric conditions. [citation needed]
Sinus tachycardia is a sinus rhythm of the heart, with an increased rate of electrical discharge from the sinoatrial node, resulting in a tachycardia, a heart rate that is higher than the upper limit of normal (90-100 beats per minute for adult humans). [1] The normal resting heart rate is 60–90 bpm in an average adult. [2]
This may start a vicious circle, in which cardiac output is reduced as oxygen requirements are increased. [ 3 ] Afterload can also be described as the pressure that the chambers of the heart must generate to eject blood from the heart, and this is a consequence of aortic pressure (for the left ventricle) and pulmonic pressure or pulmonary ...
