Diastolic dysfunction and tachycardia
WebIt is due to an increased resistance to ventricular filling and results in an inappropriate upward shift of the diastolic P-V relationship, especially during exercise. This leads to exercise intolerance with symptoms of congestion. The causes are known, ie, impaired systolic relaxation, decreased diastolic compliance, and inappropriate tachycardia. WebApr 23, 2024 · Cardiac causes include arrhythmias (tachycardia or bradycardia), structural heart disease, and myocardial dysfunction (systolic or diastolic). Noncardiac causes of congestive heart failure include processes that increase the preload (volume overload), increase the afterload (hypertension), reduce the oxygen-carrying capacity of the blood ...
