Intracoronary electrocardiogram.
SEE PAGE 988 A nimal studies on the intracoronary electrocardiogram (IC ECG) preceded coronary angioplasty, today referred to as percutaneous coronary intervention (PCI), by 1 year, almost 40 years ago (1). Even the balloon was there, but it was used for temporary coronary occlusion producing ischemia rather than for treating coronary stenoses. In 1983, pacemaker electrodes were used to derive ...
متن کاملMethods of Teaching Electrocardiogram: Which One Is the Best?
Introduction: There are many methods for teaching ECG interpretation, but deciding on the best method is yet to be discussed. The purpose of this research was to examine teaching methods for ECG interpretation and introduce the most effective ones. Methods: This systematic review was conducted by searching through scientific databases of PUBMED, Science Direct, SID and IranMedex. Papers publish...
متن کاملValue of the intracoronary electrocardiogram to monitor myocardial ischemia during percutaneous transluminal coronary angioplasty.
To enhance detection of ischemia during percutaneous transluminal coronary angioplasty (PTCA), unipolar intracoronary electrocardiograms (ECGs) were recorded during PTCA in 25 patients from the tips of guidewires positioned distal to stenoses being dilated. Surface electrocardiographic leads chosen to reflect likely areas of reversible ischemia during PTCA were recorded simultaneously. In 21 of...

متن کاملIntracoronary electrocardiogram ST segment shift evaluation during intravenous adenosine infusion: a comparison with fractional flow reserve.
BACKGROUND By measuring the pressure decline caused by coronary narrowing, fractional flow reserve (FFR) is an index of the physiological significance of a vessel stenosis. Intracoronary electrocardiogram (IC-ECG) recording from an angioplasty guidewire is more sensitive than standard ECG in detecting regional myocardial ischemia. The aim of the study was to assess if unipolar IC-ECG ST segment...
