Journal ArticleDOI
Electrocardiographic “pacemaker pseudospikes” and radio frequency interference
Mark J. Cleland,Edward T. Crosby +1 more
TL;DR: In the case described, the monitor was presented with RFI signals and interpreted them as pacemaker spikes, generating a tracing suggestive of pacemaker malfunction, and Troubleshooting strategies and minimizing the potential impacts of RFI on patient monitors are discussed.
Journal ArticleDOI
Effect of myocardial revascularization and vein graft blood flow on pacing function.
TL;DR: The results of this study suggest that pacing function measurements are sensitive to changes in vein graft blood flow and may provide useful information about the condition of the myocardium, especially immediately prior to weaning from CPB.

Effects of Changing Heart Rate in Man by Electrical Stimulation of the Right Atrium Studies at Rest, during Exercise, and with Isoproterenol
TL;DR: These studies indicate that in the absence of augmented metabolic requirements, homeostatic mechanisms maintain cardiac output relatively constant despite large induced changes in the heart rate, however, when metabolic demands are increased by muscular exercise, or the circulation is stimulated by catecholamines, cardiac output can rise through an increase in stroke volume, even when alterations in theheart rate are prevented.

The clinical significance of bundle branch block complicating acute myocardial infarction. 1. Clinical characteristics, hospital mortality, and one-year follow-up.

TL;DR: In many patients MI with bundle branch block is associated with severe heart failure, however, this was not true for a majority of the patients, in whom therapy aimed at preventing morbidity and mortality due to the bradyarrhythmia of advanced AV block might be beneficial.

Value of the H-Q interval in patients with bundle branch block and the role of prophylactic permanent pacing

TL;DR: In this population, H-Q greater than or equal to 70 ms was an independent risk factor for progression to HDB, prophylactic pacemakers relieved neurologic symptoms but did not prolong life, and a subgroup at particularly high risk was identified.

The clinical significance of bundle branch block complicating acute myocardial infarction. 2. Indications for temporary and permanent pacemaker insertion.

TL;DR: Patients who survive high degree block with MI should receive temporary and then permanent pacing, and patients without high degree AV block during MI who nervertheless have a high risk of sudden death may benefit from permanent pacing.

Hemodynamic benefits of atrioventricular sequential pacing after cardiac surgery
TL;DR: In selected patients after cardiac surgery, temporary A-V sequential pacing is a workable and valuable adjunctive form of hemodynamic support and is preferable to ventricular or atrial pacing.
