TLDR
It would appear that transient increases in heart rate induced after AMI reduce myocardial performance in the subsequent period.About:

The Use of Artificial Pacemakers in Acute Myocardial Infarction
TL;DR: The earliest hopeful specific reports on the use of transvenous endocardial pacing in acute myocardial infarction date from 1963 and a decade later, during which period hundreds of cases have been reported, it appears hopeful but still uncertain of its overall value.

Diagnosis of cardiac rhythm with transmitral flow.
TL;DR: Whether or not the ECG tracing is unreliable, an accurate diagnosis may be made with Doppler interrogation of the TMF, and a specific treatment may be indicated, such as cardioversion or transvenous, epicardial, or transcutaneous pacing for enhancement of left ventricular preload or even increased contractility.

Factors Influencing Infarct Size Following Experimental Coronary Artery Occlusions
Peter R. Maroko,John K. Kjekshus,Burton E. Sobel,Tan Watanabe,James W. Covell,John Ross,Eugene Braunwald +6 more
TL;DR: It is concluded that the hemodynamic status and neurohumoral background at the time of occlusion and for up to 3 hr thereafter can alter the extent and severity of myocardial ischemic injury andMyocardial necrosis.

Hemodynamic determinants of oxygen consumption of the heart with special reference to the tension-time index.
TL;DR: The hemodynamic determinants of myocardial oxygen utilization were ascertained in the isolated, metabolically supported, nonfailing canine heart and the primary determinant was found to be the total oxygen requirement.

Systolic Time Intervals in Heart Failure in Man
TL;DR: It is postulated that a defect in the mechanical performance of the heart is responsible for the abnormal systolic time intervals in human heart failure.
Journal ArticleDOI
The Relationship of Alterations in Systolic Time Intervals to Ejection Fraction in Patients with Cardiac Disease
TL;DR: The relationships between the systolic time intervals determined from simultaneous recordings of the electrocardiograms, the phonocardiogram, the carotid arterial pulse tracing, and direct measures of left ventricular performance as assessed angiographically by measurement of left Ventricular stroke volume and ejection fraction were studied.

Electrical Stability of Acutely Ischemic Myocardium Influences of Heart Rate and Vagal Stimulation
TL;DR: It is concluded that increasing HR within a physiologic range by diminishing vagal tone during myocardial ischemia decreases electrical stability of the ventricle by increasing ischemIA consequent to the rate-induced increase in myocardian oxygen requirements, and a direct electrophysiologic action of the vagus on the ventricular myocardium.
