Systolic time interval fluctuations produced by acute myocardial infarction.
Studies were made of serial recordings of electrocardiogram, phonocardiogram, and carotid pulse in Ij5 patients admitted to a coronary care unit with recent definite uncomplicated acute myocardial infarction. None of the patients received digitalis preparations, diuretics, or other drugs thought to influence myocardial performance. There was abbreviation of the electromechanical (QS2) index and...
متن کاملApex cardiogram and systolic time intervals in acute myocardial infarction.
cent a systolic 'bulge'. The a-E interval and the time to the systolic peak of the apex cardiogram were significantly shortened. The systolic time intervals showed shortening of the pre-ejection period i, isovolumetric contraction time, electromechanical systole, and ejection time along with the E-J interval which represents the phase of maximum ventricular ejection. The changes observed were t...
متن کاملChanges in systolic time intervals in acute myocardial infarction.
After acute myocardial infarction there is a shortening of the QS2 interval and the ejection time. The pre-ejection time is either normal or prolonged. After the stage of maximum shortening of the QS2 interval and ejection time, there is a progressive improvement towards the normal. In this study there was no correlation between the shortened QS2 interval and ejection time, and the level of uri...
متن کاملRapid Diagnosis of Acute Myocardial Infarction
To improve the specificity of biochemical markers of myocardial infarction (MI) a method to measure cardiac troponin-I (CTn-I) was developed. CTn-I is a protein unique to cardiac muscle and is released after MI. Consecutive 150 patients admitted to the coronary care unit was studied. Value of CTn-I was determined in all samples. CTn-I concentration in the MI patients group was increased com...
متن کاملEmotional Triggers of Acute Myocardial Infarction
Introduction: Cardiovascular diseases are the leading causes of death around the world. Identification of triggers that lead to acute coronary events in ischemic heart diseases and their prevention can reduce the complications of myocardial infarction. Objective: The purpose of this study is to determine emotional triggers in patients with acute Myocardial Infarction (MI). Materials and Metho...
