Cardiovascular hemodynamic functions in complete heart block and the effect of isopropylnorepinephrine.

Effect of Heart Rate, Exercise, and Nitroglycerin on the Cardiac Dynamics in Complete Heart Block.

THE PRESENCE of complete heart block offers a good opportunity to study cardiovascular functions, since one of the major variables of cardiac activity, i.e., heart rate, is maintained constant.113 In addition, if a cardiac pacemaker is implanted in a heart for treatment of complete heart block,14-20 total control of the cardiac rate is achieved, thereby providing an excellent opportunity for st...

The effect of eight weeks of cardiac rehabilitation on hemodynamic parameters and blood lipid profile in male patients 55-70 years old CABG coronary artery bypass graft surgery

Extended Abstract 1.Introduction According to the World Health Organization (2010), cardiovascular disease (CHD) is the most common cause of death worldwide (1). Sadeghpour et al. (2010) have shown that one of the most common problems after coronary artery bypass grafting is extensive hemodynamic changes. Incomplete drainage of blood and blood fluid from the pericardium and pleura reduces hea...

A Lumped Parameter Method to Calculate the Effect of Internal Carotid Artery Occlusion on Anterior Cerebral Artery Pressure Waveform

Background and Objective: Numerical modeling of biological structures would be very helpful tool to analyze hundreds of human body phenomena and also diseases diagnosis. One physiologic phenomenon is blood circulatory system and heart hemodynamic performance that can be simulated by utilizing lumped method. In this study, we can predict hemodynamic behavior of one artery of circulatory system (...

Effects of Postconditioning, Preconditioning and Perfusion of L-carnitine During Whole Period of Ischemia/ Reperfusion on Cardiac Hemodynamic Functions and Myocardial Infarction Size in Isolated Rat Heart

Effects of remifentanil and alfentanil on cardiovascular responses to tracheal intubation

Introduction: Laryngoscopy and tracheal intubation necessitate to start a surgery and induction of general anesthesia as well as the maintenance of the air way and to provide ventilation. However, Laryngoscopy and tracheal intubation may lead to hemodynamic response that appear with the symptoms of hypertension tachycardia, arrhythmia and myocardial ischemia and results in myocardial infarction...
