Hemodynamic Effects of Tachycardia in Patients with Relaxation Abnormality: Abnormal Stroke Volume Response as an Overlooked Mechanism of Dyspnea Associated with Tachycardia in Diastolic Heart Failure

Results of our study suggest that an inadequate SV response to tachycardia may play an important role in the production of dyspnea associated with tachycardia in these patients.
